BCM Replacement Dodge Caravan 1996-2000

[@mattmgarza]

As some folks have said, no need to take the junction box thing out but the OP had his reasons for doing so. But to just take the BCM, take off those two big-ass plugs at the bottom, just squeeze the tabs, no nut or bolt. Then, the 3 screws that are facing you that require a 10mm socket, remove those. Then, as he shows in the video, the 2 screws with the 8mm head, and then the one on the other side at the top. You'll need some extensions for that one and a flashlight but keep looking for it, it's there. Thank you OP for a great video, couldn't have done it without you.

[@TheOldbikerider]

Thanks for the helpful video. I just completed this task on a 1998 Dodge Grand Caravan. I bought used BCM on Ebay but kept the fuse/relay panel. I made the mistake of disconnecing the face plugs. As noted in the previous comments, this is unnecessary. Anyway, a tip for getting them back on: install them and the plugs on the bottom before installing the assembly.

[@brianwinter1453]

you dont have to take fuse box all the way down. take the 3 8 mm bolts out of it an slide down disconnect the two plugs on bottom. it will slide right out

AFTER PULLING OUT MY CONTROL PANEL AND CHECKING ALL THE SOLDER POINTS (AND POSSIBLY KILLING MY ODOMETER) I HAVE DECIDED THAT WHAT I THOUGHT WAS MY PROBLEM (ACCORDING TO THE MAJORITY OF INTERNET OPINIONS) IS NOT ACTUALLY MY PROBLEM. THIS SEEMS LIKE A REASONABLE NEXT STEP. I DO NOT HAVE ANY WORKING GUAGES AND SO I GET HOW AWESOME IT MUST FEEL TO ACTUALLY HAVE THEM WORKING. I JUST NEED TO GET MINE WORKING NOW

I think I may have a BCM faulty unit also as I have two problems one is minor in nature the other is CRITICAL. - - -THE MINOR PROBLEM - - - The minor problem deals with the overhead trip computer display. In one of the selections you will see dual display of MPGs. - - - Under normal conditions the left display shows AVG MPG, the right display shows INSTANTANEOUS MPGs, the next step shows INSTANTANEOUS MPGs by itself. - - - Now the problem, in the dual display step, the AVG MPGs display is blank but, has moved the display to the right into the INSTANTANEOUS MPGs position. Further, the next step displays INSTANTANEOUS MPGs is correctly displayed by itself. I changed out the display module to no avail the problem continues. - - - THE CRITICAL PROBLEM - - - The critical problem deals with "Daytime Running Lights (DRL) / Hazard - Turn Signals" integrated module, about $100 for this bit of technology. - - - Under normal conditions when the Light selector on the dash is set to the "Automatic" position, the DRLs work when the vehicle is in motion the head lights are on and if at night the head lights and other outside lights switch on. The Hazard - Turn Signals work by pressing the "HAZARD" button all turn signal light flash together. The turn signal works by moving the signal lever up for right turn and down for left turn. - - - Now the problem, intermittently the Hazard / Turn sSignals do not work. Checking fuses under the hood at the power distribution block indicate all fuses good. Some video postings suggest removing the DRL/Flasher module opening it up and re-soldering the solder joints to correct for possible cold solder joints during production. Based on this video and others I suspect a defective BCM. I'll keep you posted.

[@rogerd4559]

there are videos on how to repair a defective BCM the same way by resoldering the solder joints. I had to resolder my dashboard instrument cluster because of cracked solder joints and it solved an intermittant instrument cluster. At least give the soldering fix a try before buying a new one

[@mars188]

wished you shown how to get the emergency break out from the plastic cover it is hooked too- i thought it snapped out so far no scared i might break something the darn thing is in the way. doing this job now. have the same part coming from ebay just like this one. hope i can do the job get my old van back on the road

Thanks a bunch... I have a 98 Dodge GC, same issue been driving it a long time without gauges--already changed some stuff I thought was wrong...the BCM is the last piece.

I got tired of getting stuck cause I ran out of gas and had a tow truck charge me for ten gallons of gas when he only added 5! (he hid the capacity on the gas can from me)

[@mars188]

did the same this week haa- spent 300 bucks so far this is the last part- if this dont work i am lost with it nothing else to change out haaa

[@rogerd4559]

It was totally unessesary to remove the whole juntcion block, fuse block and relays and risk disaster of reconnecting all those connectors wrong. and 10 times the extra work. all you had to do is unbolt the junction block from the dash panel/firewall, lift it disconnect two cponnectors from the BCM, loosen the 4 screws holding the BCM to the junction block then slide it out. I can understand why you did that though. you wernt able to buy a BCM seperate from the Junction block so you went with replacing the whole unit combination.

I've got a '98 Town and Country with locks that cycle on and off very quickly, the instrument panel dies for a split second at a time when driving, battery light is on, and battery is always draining. Sometimes the locks will also just cycle on and off in a normal speed, but, that's also undesirable, lol. Hopefully changing this out will help.

I remember riding in someones van back in the late 90s that the locks were going crazy like that! Not sure the root cause on that one but it sure is crazy

[@henryssurfshowcase]

I have a 1999 dodge caravan 3.3, my speedometer goes out sometimes. Engine light comes on says BCM. Are these hard to find?

[@CarsandCoding]

Not hard to find. Check eBay, or your local auto salvage yard. These vans were made by the hundreds of thousands. Still plenty of them in junkyards. Buy two or three bcms and one will work for sure. You don’t need the whole fuse block like I did, but it doesn’t cost any additional if you pull it yourself at the junkyard.

[@n8chz]

At 0:48, the 4 nuts holding down the electrical connectors, I'm finding the 11mm too large and the 10mm to small. Is this a 10.5mm (or dog forbid a 13/32 inch)? I've reached an impasse. It seems I will have to special order a very rare tool. Am I missing something?

[@CarsandCoding]

I didn’t use any special tools. If 11 mm is too big stick a gum wrapper in the socket or a piece of tape or paper or aluminum foil

[@LokiX76]

Great video. Thank you. I am likely going to have to do this for my nieces 1998 grand caravan. do you know of any "learn" routine the BCM has to do to sync up with the ECU or any sort of re-programming that needs to be done? Also, is the vehicles mileage stored in the BCM or the ECU? All my past experience is with ECU. But never had a car with a stupid BCM to go bad. Just wondering if the mileage on the odometer is going to read differently. Thanks again.

[@rogerd4559]

this guy claims you can reprogram the BCM by this method... but it could be risky to the rest of the circuits as it involves plugging and unplugging computer modules without disconnecting the battery... also a risk of setting off the airbags and having them break your nose... kzbin.info/www/bejne/pmrVXmxnaa9pmKs How TO PROGRAM A BCM ...

they say on here you have to get the BCM reprogrammed. Some sellers on EBAY will reprogram the BCM they sell you with the VIN number you supply them

[@ballhawk387]

I attempted the easy fixes and solder connections with no luck, and also had wonky wiper behavior, so it looks like this is the issue. A question before I plunk down for the BCM: did the gauges go on and off intermittently before they went totally dead? Mine were going on and off for a few trips, then went out.

[@CarsandCoding]

Yes the gauges would work once in a while and when they did it was like I hit the lottery

[@DazedNConfuzed58]

I just replaced my Gauge cluster with another one from a Pick a Part. I originally had the dead gauge syndrome & banging my dash brought it back to life until one time it went dead permanently. I did try the soldering repair thing on the main connector to the circuit board, but that didn't last too long. All is good now except for one thing... since I bought the van 3 or so years ago, the gauge lights have always been out. I've checked wires for continuity, bulbs and fuses. All are good. Could it be the BCM is afu & needs to be replaced?

[@CarsandCoding]

Since you replaced the cluster, you know the problem is elsewhere. Post your question to forum.chryslerminivan.net/forumdisplay.php/30-3rd-Generation-Chrysler-Minivans-1996-2000

[@rogerd4559]

I saved myself alot of money by repairing the cracked solder joints I followed the advice on a video here on You Tube the solder joints on the ground pin of the instrument cluster breaks from vibration. by repairing the gauge you dont have to go through recalibrating the instrument panel with another one

[@JisINSANE3]

i have a 98 dodge caravan. And i have every intention on setting it on fire when i get a new car. New starter, Alternator, Power steering pump pulley since its made of plastic and sheered off without warning, TOWED New brake lines that where rotted and started leaking with no brakes to stop, TOWED. Drivers side window does not go down, Passenger side only works somtimes. Heater blower motor needs kicked to work somtimes, Fuel gauage goes to empty then back to what its actually at and beeps low fuel ligt 35 times a minute. Oil light flashes at idle, Burns oil, Leaks oil, Water pump leaks slowly, Muffler rotted and replaced, Wipers only work on low or high no delay, heat and ac only work on high, Body is rotting, Paint is worse then a 1991 chevy, Vacum hoses are cracking and breaking, Exhaust leak at the manifold, headliner sunk, Power door locks on front doors shot.Transmission slips when super cold, Belt drive engineered with smooth idler and tensioner pulleys so everytime it rains the belt simply falls off and in some cases ruins the belt. TOWED. Tow bill $100 a pop. 191k Miles. Nuff said.

[@CarsandCoding]

JisINSANE3 Post your question on this message forum, I'm sure someone will answer you. I think it could be the BCM, but could be something else. forum.chryslerminivan.net/forum.php#/forums/30

pretty sure its not the BCM, But since you said it im sure that will go out next and ill have another $100 tow bill and it needs to have 49.9 pounds of tannerite put in it and exploded.

[@CarsandCoding]

A lot of the things you mentioned are basic maintenance. Hoses don't last 20 years. Neither do starters, alternators, brake lines, water pump. The belt you can replace with a upgraded tensioner. I fixed all the things you mentioned on my 1997 Dodge Caravan in the first year I had it (I paid $1200 for it initially), and once I got everything fixed in the first year, I drove it 40,000 miles in 3 years. The final straw for me was water leaking through the roof in the back and a colony of ants that made its home in the HVAC that I couldn't get rid of. So I sold it for $800 and bought a new Golf Sportwagen. The dodge caravan was a cheap ride that could haul a ton of stuff. No regrets.

[@JisINSANE3]

Glad you had luck. I just put the doorman pulley shields on it and a new belt 5 days ago. I refuse to drop any real money into it. But so far so good in rain. Its just a worn out Piece of *hit. And a mechanics nightmare on how they designed it.

my god why did you keep it so long? My 98 Voyager (almost the same had these same problems) but it was free they say if you want a car to last, you garage it the raodsalt is the major devil that rots out all your brake lines and yes the paint on chrysler has always been an issue as I think back about my neighbors duster that looked like it had a bad sunburn

[@ginginthing]

Great video and very informative on how to do this job. I wish u went into more details on why u R&Red this BCM. Since it's a huge job, I need a little more than just the instrument cluster being out. My instrument cluster went out on my 98 dodge caravan 3.3l went out and the problem was the instrument cluster. Bad solder joints. Resoldered and back on line. If I would have replaced the BCM, the instrument cluster would still be bad.

[@CarsandCoding]

Instrument cluster was out, odometer did not show any numbers, speedometer didn’t work, gauges would randomly work, interior lights such as doors and dome light would randomly work, windshield wipers would wiggle randomly. Like the wipers didn’t come on randomly, they would jiggle in place, like move a quarter inch. Random stuff. But I replaced the gauge cluster and that didn’t fix the issue so then I went to the BCM next.

[@CarsandCoding]

braden cunnington remove the instrument cluster and re solder all the connections on the back first. Heat them up with a soldering iron so they melt. Then reinstall. it could be a bad solder connection on the circuit board. there are you tube videos for that also. try that first!

[@rogerd4559]

I had just the gauges not work a year ago and it turned out to be broken connections on the circuit board by the connector ground. there was a youtube video on gauges malfunction that saved me hundreds of dollars.

[@rogerd4559]

Chryslers are plaged by broken solder connections on the instrument cluster. I suggest you carefully remove the gauges unscrew the back cover and inspect the solder joints for cracks around the main connector this will not only save you money but then will not be nessesary to recalibrate the gauges and you will keep your mileage setting

My 1998 Grand Caravan Remote door looks wont work. They do lock with the remote but then they keep wanting to lock about every other minute. Then it runs the battery down. I took out the black relay box out of the fuse box now I have to use the keys to enter the car. My question is could this be the Body Control Module? Also do you know the part # for this? And what size wrenches do you need to remove the fuse box and the wire connectors? Thanks

[@CarsandCoding]

Dennis Fucci not sure. Is the problem only when you use the remote? To replace the bcm you need to get one from the same year van with same options. Especially if you have theft system. No special tools to remove/install, just what you see in the video. Unfortunately you can't read the part number until you remove it, so you roll the dice if you get one from ebay or junkyard without the number.

Do not have a theft system. Have tried everything and took it to 2 garages and they think the BCM is my problem. Another question when you install a new one to they program there self or do you need a special tool for that. Thanks so much for your help.

[@CarsandCoding]

Dennis Fucci there is nothing to program but they keep the mileage of the junkyard car. So if you want the mileage programmed you need someone to do that for you. Might be worth it in your case since you have such low mileage. Bcm is about $40 at junkyard, but probably $150 to set the mileage. I did not program mine because I don't care about mileage. Get one and try it first before programming though in case you get a bad one.

[@rogerd4559]

These cars are incredibly difficult to work on cause they change back and fourth from ASA to metric, I think those 4 connectors I used a 7/16th short socket on a 9 inch extension I cut one end off the extension so it would fit in my cordless drill. I backed them out in 5 seconds. the two white BCM connectors on the bottom must be dosconnected first as the cables are so damn short that they wont release the juction block and BCM. after unfastening all 6 connectors the whole assembly will drop right out

Stephen Bannworth There are multiple things that could cause failure to start. Do a search for it in the forums on chryslerminivan.net funny as it sounds one of the common problems is a bad solder joint in the instrument cluster, which can be temporarily fixed by hitting the top of the dash. forum.chryslerminivan.net/forum.php

The clock. It controls your air bag timing and horn. Its in the steering column and its the first thing you see when you take off the steering wheel

[@CarsandCoding]

Marcus Butler Ok the clock spring. The clockspring is a common problem and is still covered under a lifetime warranty in the USA. I would say that the BCM could be your problem but the fact that your windshield wiper problem started when you replaced the clock spring, probably is related to the wiring in the column. I am not an expert though.

[@EdwardBaker94]

its a mystery. everything else works perfectly. Dealership wanted 500 for a new windshield wiper switch, when i already changed it with a new one from auto zone and a used one from a junk yard. Told the guy its not the switch but he insisted. I said if its not the switch he gives me back the $500. Get a call after i take it in...Mr. Butler, thats not the problem you can pick up your van along with the $500.

check the parking switch in the wiper assembly first in might be sticking or open If that sticks it may continue to operate your wipers

[@judyhenley6978]

I have one of the nuts stuck in the top left connector. Will look hard to remove!!!! Please help.

[@rogerd4559]

they are a terror to remove. is the nut disengaged from the stud? Maybe all those harness in the way are interfering? I did that top left connector last then was able to drop the whole BCM and Junction block down as one unit the manual states, you must disconnect the two lower connectors on the acual BCM on my van they are two white connectors push the tabs inward....careful they break off easy

I had some trouble with the face connectors. 3 of the 4 backed out as they should but the upper left would not come out on it's own even after the nut was completely loose. I had to carefully use a screwdriver to pry it slightly loose. Then it came out. Same troublr getting it back in. Took forever for the nut to engage the bolt. Those are all back in and now I have another problem. On my fuse panel the front connectors were all color coded so I didn't need to label them. However, the two bottom plugs looked as though they were only able to go one place each due to the length of their wiring. It took so long to get the new BCM that the wire hung loose and now seem to have enough length to fit on either side. Before they are plugged up I'd like to know which goes where. One comes from the floor and the other from overhead. Does anyone know which plugs where when looking at the BCM with it mounted in place?

[@alanross8313]

Looking towards the front of the van the overhead plug goes into the bottom right side of the BCM. If you have the junction block bolted to its mounting it is a tight squeeze to get the left hand plug inserted. Just pull the carpet out of the way and it will go in.

[@rogerd4559]

I believe the one from overhead goes on the left and the one from the floor is on the right not sure because I had the common sense to mark all my connectors before removing them

[@Vafamkulo74]

changing cmb which codes must match?

[@CarsandCoding]

Try to get same year and options.

[@Vafamkulo74]

i had p4748382, changed another. the wipers operate with the ignition off and the central locking system does not respond

[@CarsandCoding]

@@Vafamkulo74 do you still have your original? You may be able to repair it with the parts from the others. I am not an expert on these, I had to try another one before I found one that worked also.

[@clevengermeister]

i own a 2000 dodge caravan. 3.3leter motor. when i hook up the battery my lights come on,windshield wipers,and my horn come on also. can you help.

[@rogerd4559]

I watched a video where this mechanic traced all these problems to a bad ground. a bad ground can sometimes make the BCM go crazy like that

[@luiscarlosolmedoxi]

How did you take out the connectors from the fuse box? Ive been trying but they seem to be stuck, please Help

[@CarsandCoding]

Luis Carlos Olmedo you have to turn out the bolt in the center of each connector, then they come off.

[@luiscarlosolmedoxi]

So that bolts come out completely? Ive been trying to take them out with a wrench but in a certain step the bolt doesnt come out, It look like It is stripped because i continúe on turning with the wrench and never end. This happens with all the 4 connectors. Dont know if you can show a rear view of the connectors please too.

[@CarsandCoding]

Luis Carlos Olmedo No they don't come all the way out, loosen all the way, then pull on the connector. If I remember correctly, I thought when I loosened the bolts it made the connector come off as I loosened them.

[@luiscarlosolmedoxi]

thank you man, i'll try out

[@rogerd4559]

My van may be different its a plymouth Voyager but you must remove the nuts first in the center of the connectors, then wiggle them out. but you dont have to remove the junction connectors if you are only after the BCM. Just lift the junction block up after disconnecting from the firewall, pop the connectors off the BCM remove the 4 screws to the bracket and slide out the bcm

[@carslover3509]

is the gas gauge was not work before the new bcm ?

[@CarsandCoding]

I can't remember, if it is only the gas guage that is bad then that is probably your fuel pump that has a problem. I had many problems, the speedometer did not work, none of the guages worked. Sometimes they would work but most times did not at all.

[@carslover3509]

thanks friend great information

[@amelecio550]

bad b cm would make transmission not to go more than 30 rpm?

[@CarsandCoding]

no, that is the transmission control module. Go to chryslerminivan.net the minivan fanclub forums to learn all about it

[@rogerd4559]

it can be any combination of malfuntions depending on what is not working in the BCM when a solder joint cracks in the unit, it may just take out the dash lights or horn or wipers, window motors maybe the transmission. as they said in the army, the best test for anything is substitution. if you can afford it lol

[@lamborghinicentenario5203]

did you also had problem with the windshield wiper?

[@CarsandCoding]

Julian Jauregui yes the windshield wiper would come on by itself and would only work on low and high. Not intermittent setting.

[@ballhawk387]

I noticed the same thing, with occasionally wonky windshield wipers. That clues me in it's the BCM. Odd about the mileage changing, but I suppose that's where it's recorded. I can also see the scam potential if that change the milage with a lower mileage BCM. Hmmm...

[@bons562]

Could this also be why the alarm won't disable Im having trouble with ours it won't start we just replaced the computer. An it still won't start

[@bons562]

I was told also the cluster might be fried it works turns on fine but before all this happened the rpm Gage wouldn't work I'd have to slap the top of the dash for it to work when it was running. Any help I would appreciate. 👍

[@CarsandCoding]

Yes, some vans had a theft system. You have to make sure the bcm is not from a theft system alarm van.

[@youtubecommentpolice2043]

cuda2000 what! Make sure the BCM is not from a theft system? WTF are you talking about

[@CarsandCoding]

youtube university some vans had a factory alarm which disabled the ignition

[@youtubecommentpolice2043]

cuda2000 yea I know. But how ever you were explaining it, ...... didn't make complete sense. All good. Good luck

[@bradfordknight9196]

Does the BCM on these vehicles need to be programmed by a dealership or someone with a programmer?

[@CarsandCoding]

They dont have to be reprogrammed unless you want the mileage displayed to match what it was. The mileage will read whatever the donor car had on it.

[@barbarawilliams7018]

+cuda2000 If you want to reprogram the mileage is it something that has to be done by a dealer?

Dónde conseguiste la bcm

[@CarsandCoding]

EBay o la chatarrería

[@amandahinojosa344]

I have a 2013 dodge ram 1500 my truck has no crank no start I have absolutely no power I'm it no radio power locks don't work, windows weren't working either..headlight can turn on we have checked battery and that was fine. my vehicle has been at the dealership for a week now they are still trying to figure it out they have ordered a part called BCM could this cause my truck to have no power and no start?

[@CarsandCoding]

could be bcm, pcm, or wiring. Cars are computers these days!

[@rogerd4559]

I suspect so! The body control module or BCM controls all those accessories and is a notorious failure on Dodge and Crysler, plymouth products due to crappy soldering proceedures on the BCM board, instrument panel ( lets hope not the ECM) that crack over time. its a built in failure to force you to buy another vehicle. all they had to do is go the extra mile and bolt the heavy componants down to the board, rather then rely on solder to hold them in place! If it were a Military componant board in an aircraft.. you damn well bet it would be done properly to keep their helicoptors from dropping out of the sky

[@jacintohernandez3619]

Excelente video

[@gmcjimmyandblazer]

Why did you have to replace the bcm?

[@CarsandCoding]

The problems the bcm fixed for me were: instrument gauges didn't work, speedometer, tach, odometer, fuel guage, temp, windshield wipers didnt work on intermittent and key in ignition bell door open bell didn't work. Abs light was on. Replaced the bcm and everything works.

[@Eeropolvasti]

+cuda2000 Isn't that a typical instrument cluster solder joint problem, sure sounds like it?? Are you sure, that was not a problem??/ Just wondering, after seeing so , so many guys just resoldering those couple solder joints, and everything works after !!=)And, by the way, it seems, 90 % of times, always beeing just behind main plug, left one on a bottom =)

[@CarsandCoding]

+Eero Laukkanen Yes, sometimes the instrument cluster issue is a bad solder joint. I tried that, and replaced the cluster, and it didn't help. Replacing the bcm fixed all my problems and 15,000 Miles later no issues! Try the solder fix first.

[@Eeropolvasti]

OK, thanks! How much is that part? Any soldering involved changing it?? How long did it take you to change it? Must be very rare problem?? Thanks , youtheman

[@CarsandCoding]

+Eero Laukkanen The bcm can be bought used on ebay or from a auto salvage yard. $50-$100. You can't buy it new. you have to get one from the same year van, with the same options that yours has. It is a common problem. I explain most of this in the video.

[@murcielagoblack4824]

Es necesario cambiar el bcm completo en falla de tablero

[@rogerd4559]

Es cierto si se trata de un fallo del tablero. Si tiene una unión de soldadura agrietada, sería una tontería gastar cientos de dólares en lugar de arreglarlo. Muchos espectadores aquí han descubierto que con estos módulos han tenido éxito al repararlos.

[@rogerd4559]

The removal of this BCM is tough. If theywere going to put it in such an inacessable spot they could have at least built it to be reliable

[@CarsandCoding]

If you think this is tough, wait until you work on something 20 years newer! You absolutely need a computer to fix the computer, and you cant just swap parts between cars. Everything has the vin encoded. Appreciate the simplicity of the 1990s in comparison!

[@rogerd4559]
