How to repair your F-Body BCM ( Body Control Module )

Please consider Subscribing to the channel, it would really help out a lot to help be able to get some go fast parts! Thanks for watching 🇺🇲🦅💪

[@AnthonyC82]

So thankful for this video! I couldn't find anyone else who showed the process of actually removing the silly thing, which was the hardest part. I never would have figured out that you just have to bend the plastic that far to get it loose. I was able to fix my intermittent radio and windows for free which was super satisfying.

[@437MotorsportsandOutdoors]

Glad it was helpful. That's one reason I made it so detailed and long, to show everything you have to do and go through to fix it. Thanks again for watching....

[@rogerd4559]

a repair like this cost thousands of dollars and this guy if this video halps me repair it I will be forever greatful This damn Voyager has been one electrical headache after another

[@rogerd4559]

yes that is awsome. I hope to have that luck with mine. the only thing that works on my van is the engine. everything else is dead. I think it is easier to rmove my engine then to take this god awful BCM out! Chrysler sure went to alot of trouble to prevent owners from repairing their own cars. I hope those engineers rot in hell! I think i will have to buy a remote snake camera to find all the damn bolts holding this damn silly thing in! How did you ever expose the unit like that? I removed the knee block metal plate and anything else I could remove, and still cant see the top of it. but my van is a 98 voyager so maybe that is why?

[@mrkattm]

Soldering not being one of your strong suits was an understatement. I know it is an old video but for those looking for info the proper way to solder is to flood the joint with flux, apply heat to the joint with the proper soldering iron ( not a torch, not a gun but but rather a 40 or 60 watt pencil) then apply the solder to the joint once it is molten. Never carry solder to the joint with the iron.

[@coywilhelmy1626]

Just did this tonight. Took longer to pull the damn thing out then it did to figure out my soldering iron was shot, drive to the store, get a new soldering iron and solder, do the job, clean up, and retape the box. Seriously though, great video and info.

[@chrismay2298]

Nice work. Only thing I would suggest is using a solder sucker and removing their original lead-free solder before adding quality leaded. Stuff is terrible for heavier, unsupported components like those relays... 👍

[@quantumenergy3334]

As a former electrical/mechanical technician in the electronics industry and former Master Trainer that certified companies employees to IPC standards for soldering and cable harness building, you are 100% correct! Lead Free is more brittle and prone to tin whiskers. A couple of the downside to lead free. Only class 3 medical, aerospace and military applications allow the use of leaded solder. But when using lead free there are mitigations that can be used to protect lead free joints but most class 2 & class 1 products don’t often use them.

[@rogerd4559]

that makes sense. those solder joints are holding heavy componants high stress on solder joints

[@rogerd4559]

It is common sense to bolt heavy hardware down. Look at any board manufactured for the government. you will see that all havy componants with stress on them are bolted down... conectors, large capacitors, transformers etc

[@TimHaunFishing]

My only recommendation on top of this information is to always disconnect your battery before doing any electrical work in your car, especially if removing components such as radio, ECU and BCM.

[@437MotorsportsandOutdoors]

Yeah that would be my guess! When mine was acting up, it would do it in all the switch positions. The radio and the windows would not work. If yours only does it while the switch is back then it could be your switch it's self.

[@murdergang8038]

437 Motorsports no my switch is good just that my body control module is Burnt

[@437MotorsportsandOutdoors]

@@murdergang8038 Ok, then this I believe should fix it.

[@biezulbub669]

My 99 z28 just encountered this problem today of my windows and radio and power convertible top stopped working. I got the driver window to go down but now it won't go up. And the radio will try to come on so when it does I try to put the window up and the radio shuts off immediately and nothing is working :(

[@437MotorsportsandOutdoors]

This could possibly fix the problem, but no guarantee

[@rogerd4559]

I would wait 6 months (if thats your car) to put the BCM back perminantly and thouroghly test it before a perminant installation. I had to do this 5 times to my instrument cluster on my 98 Plymouth Voyager

I'm not 100% sure if you can just swap the BCM's. Beings I believe it works with the security system so a different one mite have to be programmed to work with your car security system! I would do more research on it. I only looked at how I could fix it myself to save myself money.

I have a 2002 Camaro SS and the driver window works but the passenger side doesn’t work at all. The radio cuts in and out sometimes too. Also, the power locks don’t work at all... Could all that be the BCM?

[@437MotorsportsandOutdoors]

It's kinda odd that the drive side works but I believe that the BCM could have something to do with it. Only I know to check is to pull the panel down under glove box and wiggle and move the wires go in to the BCM that tell is that is the cause. I could wiggle mine and everything would work until it lost connection again. Hope this helps and thanks for checking out the video.

[@panzerwaffen2873]

Yes sir

[@rogerd4559]

dont dab solder on it is not glue. try remelting the solder joints and use a good flux then thouroughly flush the residue off with alcohol or a flux remover as that residue will collect dirt in a year and cause all kinds of shorting problems

Just bought a 1999 v6 not running. Its been at the dealership for a month now they said that the bcm is shot. Going to send it in to get repaired at $300. Paid $1,600 for the car. $500 for repairs and $300 for the bcm repair.

That's still not a bad investment if it's up and running. But it's definitely cheaper to do it yourself, if you're able to.

I wish I knew bud, this isn't something I've ran into personally. I'd check all my fuses and pull the BCM back out and look it over for any other cracked solder joints. Other than that I'm not sure.

Same problem but....my windows still work, radio doesn't...radio fuse is not blown. Still BCM?

Not 100% sure on that. I would check voltage at different points though out the radio circuit. Check fuse panel under hood if you haven't already. Radio might have just died . Those are the things I would look at before pulling the BCM. Hope this helps

The funny thing is.sometimes after a repair They don’t stop working again until u install it back and button up the panels and go for a drive😂😂😂😜 I’ve had a few that the harness is so stiff and crammed that it rebreaks the soldier joints from the weight of the harness and the vibrations of rough roads

437 Motorsports yea my 98 firebirds bcm is doing good so far as well been over a year since the repair but thanks for posting the video! Have a great day😁

[@rogerd4559]

yes Ive had that too with my instrument cluster. It is because of poor design and expecting a solder joint to support heavy loads and with all the pulling pushing on a connector on a board like that, it cracks the solder joint over again. a properly made board will have screws to mount that connector and the solder joints just make a complete electrical path to the circuit not support the connector

[@brettbrannon4775]

jim halcom 100% correct and yes they should have had the harness screwed to the circuit board. Or hadn’t mini harness coming off the bcm to connect to the harness to lessen the load or stress in the soldier joints.

My issue is that my car won't turn off. Also, the cluster lights are all on even when I plug the battery. The power locks, windows, ac and so on do not work. Once I turn the key to turn off the car, the car stays on and the cluster lights also stay on. The only way to turn off the car is to remove the Main relay and remove the ground battery or else it will drain it. I can't find anybody to help me. I've replaced the ignition coil and it didn't help. I don't know what else to do. I'm hoping is the BCM .
