2006 Ford Crown Vic Cooling Fan Fuses & Relays

[@surgeeclipse6323]

My Electric fan stopped working on my 2006 Lincoln Town-car and caused an overheat. This video was helpful in me fixing it. It was the relay that he points out around the 1:30 mark of the video, I know many people are saying to replace the whole electric fan assembly , but this was much easier for me and the part was less than 25 to buy and was plug and play.

Great vid, thanks!

If the cylinder head temperature sensor is bad is it goin to trigger the cbeck engine light?

[@hunterlindsey9175]

A real one for giving us the proper resistance values🙌🏻🙌🏻

[@lucky-rowe2623]

So are you saying there is not a larger relay in this system? Only a fuse and a control module + sending unit behind alternator? Thanks for the help. I'm mostly a Chevy guy and they have large relay in the system.

[@kiramatullah4688]

you are a very good master

[@yavarhamishehmomen6964]

Hi. I have 2011 Lincoln Town car the radiator fan dose not turn on when the gage get half way up, but when I turn the A/C on the fan turn on. i don't know the problem is the radiator fan or temperature sensor? By the way no check engine light. Thank you.

[@kevinspeight4664]

Ok mine is reading 3.95 at 190-200 is that too much resistance

[@jericodelosreyes6023]

crown Vic 2008 if engine newly start radiator fan works but engine is hot fan working high and suddenly low and then off and then Aircon off and on and high temperature what is the problem sir

[@jonnyvargas9394]

Why my fan turns on when I turn the car on

[@kayjglasjones2244]

My transmission temp is a little to high for my liking. I install a additional transmission cooler but also want to add the auxiliary fan on the front of the cooler. Can I splice the fan into the radiator fans so they cut on at the same time or just run it from its own source??

[@midas617]

I would run it from its own source with its own relays and its own switch so you can turn it on or off at your own disposal.

[@captainamericaamerica8090]

DON'T

[@hasanalzaabi]

Hi i have a 2007 grand marquis... I tried to connect with a jumper starter directly to the fan it did not spin until I just move it by my hand, I tried the same thing on the module result was same. , fuse looks fine the module was replaced with a new one OEM a year ago. Heat sensor reads normally. Only on a cold start the fan spins when switching AC on after reaching operating heat every time I stop AC is not cooling. should i replace the fan motor? Or there is something I am missing?

[@captainamericaamerica8090]

Replace the whole unit. Dorman makes a great one

[@NightRider-16]

So I have a 2006 crown victoria and my fans are constantly running only when AC is on. When I turn AC off they stop. What could Cause them to run constantly?

[@hasanalzaabi]

I guess my grand marquis problem is that Engine cylinder head temperature sensor, i replaced bouth fan & module still not workin.

[@benjiarambula2133]

Great help thank you

[@encinobalboa]

Good video. Fan module and fan motor can be replaced without replacing the complete assembly. Cylinder head temp sensor explanation is very good. Note the condition of the connector wire, the flex tubing has disintegrated exposing wire to more engine heat. Heat increases wire resistance which could cause PCM to read higher sensor temp than actual. Heat causes PCM to retard ignition so the result is lost engine power. Replace the flex tubing.

[@captainamericaamerica8090]

Too Much time and work to replace module plus fan motor adds up to small savings. Best to replace the whole fan assemble. Cheaper in the long run. We love Dorman! Great price and quality. All the components are there.

[@NightRider-16]

That makes sense.. So if my fans constantly run when AC is turned on, could that be due to this wire being bad or what u think?

[@encinobalboa]

@@NightRider-16 Fan is supposed to run constantly when a/c compressor is engaged.

[@ericarnold8990]

Great video! I have a 2001 Mercury Grand Marquis and the cooling fan doesn't come on unless I have on the a/c. It starts spinning fast and then slow. The fan won't come on unless the a/c is running but still runs hot. Any ideas? Thanks in advance!

[@TheQuirkyPicker_Chad]

I have the same issue on my 2002 Mercury Grand Marquis. Whenever I start it I just make sure the defrost is on and then the fan runs. After it started I could shut the AC off and the fan will still run but if I shut the vehicle off and then turn it back on without the AC on the fan will not kick on no matter how warm the temperature is

[@NightRider-16]

I have no check engine code or anything wrong but my cooling fans constantly run when AC is on. What could this be?

[@pgexpress3378]

In my 2008 crown vic police interceptor the fan module was damaged, I did a voltage test and it only raises 4 volts. I bought a new module and when I installed it it didn't give me a single volt, so I went back to the store and talked to the supervisor and told him what was happening, he gave me a different module but it doesn't work... I put the module back in original and it gives me a reading of 4 volts. I do not know what it could be

[@darwincoloncolon3432]

Hello friend, I have a situation with a crown vic 2011, previously another mechanic had already worked on the car and did not find the problem and put the fan directly on the battery, I tell the customer to buy a new module, thermostat and the temperature sensor to be sure that everything is new and to turn on the fan, everything new is installed but even so the fan does not turn on as it should, there is voltage for the fan to turn on but apparently there is no ground, so I do a ground alternated, well the fan starts but does not turn off, it remained active even with the car off, what can you suggest to me regarding this .. I will wait for your answer and thank you

[@kscrm_6883]

[@berniceperry8898]

Relay could be stuck on....

[@kevinspeight4664]

Hey Love the helpful videos. But my 08 crown Vic has been a tank up until last week only running hot when idling. Fan doesn’t seem to be working but all fuses relays and it getting voltage, the Only thing that’s sus is the ohms reading on the last plug u showed us in the video. It’s reading 3.95 w engine at 190 maybe 200 degrees. My ohm reader is old I think it only works on (20k) setting, would that be a factor. I’ve spent so much on parts in two days while driving the 2500hd to work (GAS SUCKR) so there’s that. And NOW only to find that the fans is not kicking on. Please tell me it the Drivetrain Temp Sensor and not Fan Motor. Jk either is cool lol… 🤦‍♂️🤷‍♂️ Thanks man your Videos are sooooo helpful.!!!💯🙏😎

[@kendricdavis7130]

I'm having a similar problem with my 07. On hot days at idle my fan will stop working and run hot sometimes vs when driving with ac it runs.

[@gregmeeks2753]

my fan does not spin freely ...could that mean the fan is bad ?

[@keepit100stayprayedup2]

I have a 08 grand marquis everytime I turn on ac its kicks in and out change fan module still doing it causing it to run hot only if ac is on only code it saying is the sunload sensor that's on top of the dash is that it or the climate control and also changed thermostat

2005 police crown vic ---- BRO I NEED HELP! been having overheating issues & replaced everything in the system. NOT overheating anymore but the radiator fan goes to high after only 5 mins of running. stays on high fan until shut off. replaced the radiator, water pump, CT sensor, HT sensor, thermostat (160), fresh coolant after 3 flushes. used a laser temp tool & highest reading on cyl or anywhere, is only 160 degrees. fan will be on HIGH with that LOW temp. CANT FIGURE IT OUT & NEED TO SELL!.

[@hasanalzaabi]

Just to let u know guys problem solved... The problem in my car was in module i placed the module that came with the assembly (fan-frame-module) from the junk yard... I installed the one i used b4 and the fan worked.

[@tombrinkert3720]

Good vid,I find if you disconnect the cyl temp sender the pcm will command the fan to high cause it thinks sender has failed ,something that may help in troubleshooting any issue

[@denzeltucker2920]

Hey man I did exactly that and my fan engaged on my 07 after I replaced almost everything besides the fan itself but I cannot find the exact cause because it will only engage with temp sensor disconnected

[@tombrinkert3720]

@@denzeltucker2920 Hello Denzel My grandsons ex 2011 cop car was over heating in traffic so I had to study up on the cooling fan operation.If you can dissconnect cyl head temp sensor and the fan runs on high consistently then in my opinion things are ok from the pcm out.I would still inspect your connector at the input side of the module and the connector on the output side of the module ,they both melt ,quite common,I also used a headlight and jumper wires to double check the current at the input side of the fan module to load it and make sure the current there is up to snuff .That being said if everything passes inspection you may have to roll the dice and try a pcm Regards

My 2008, only blowing hot air any tips?

[@caroleatkins6012]

If the fan is turning then recharge your A/C for about $20-30 bucks. If fan is not turning then replace the Fan Control Module for about $30 bucks. If that doesn't work replace the entire Cooling Fan Assembly for about $200. If the A/C works while the car is moving and gets warm at idle it's usually the Fan Control Module or entire Cooling Fan Assembly. Hope that helps.

Same here? Only when AC is on though. Find a fix?

[@JustinLaFleur1990]

I got a 1999 CVPI and it does pretty much the same thing. The car overheats when the AC is on, replaced the compressor, condenser, accumulator, orifice plug, and radiator cooling fan. Also replaced the relays and fuses and radiator. And after all of that the damned thing still overheats when the AC is on, the compressor clutch kicks on and off and the brand new radiator fan doesn't come on I'm at my wits end, got the replacement cable for both the fan and the compressor and gonna use my guages to check refigerant levels.

"2006 Ford Crown Vic Cooling Fan Fuses & Relays" no mention of relays in your video though..

[@chachavessel]

I was told to check the relay, is there a relay on an 08?

[@nickcarter9373]

Have the same question did you find it?

[@chachavessel]

@@nickcarter9373 there is no mechanical relay. the speed controller mounted on the side of the shroud is both a Solid Sate relay and speed controller. This is replaceable and can be purchase separately. I got it on amazon and solved my problem of not turning on. These usually go bad and could possibly cause a slight load on the battery causing your battery to slowly drain and go dead if the motor does not turn on at all. usually if you don't drive it a lot or the battery is at its end of life. This happens when the MOSFET inside are slightly leaking instead of a full dead short which would cause the fan NOT to turn off. Note: A shorted speed controller would cause the fan to run continuously, if the MOSFET's inside are slightly leaking (source to drain), it would not turn on the fans, but MIGHT cause some current drain and might slowly drain your battery. If they are completely OPEN, they will not run at all. *Please keep in mind that this is from an electronics point of view and not from a Ford mechanic.

[@REVNUMANEWBERN]

@@chachavessel Big help thanks, Can a hot wire be run from the fan plug itself to positive battery terminal for emergency to get it to shop? If yes what gage wire and to WHICH terminal of the fan plug should I attach it??

[@chachavessel]

@@REVNUMANEWBERN Yes, you can. That was going to be my plan b option. Run a true 10AWG wire, with a fuse preferably to the positive terminal, 30Amp for extra measure. Another idea would be to use a mechanical relay 30amp, the coil would be energized when you turn the key, thus it will always run, but only when you turn the key. You could find a tap in the fuse box with a multi meter. You'll have to go back & fourth to find 12volts, unless you have another person to help you. Yet another option would be to add a thermal switch to activate the coil. In this manner it would turn on and off as needed. They sell them The same relay harness you would use when mounting extra lights. If you need further help, just leave a message here.

[@chachavessel]

here's a link I found while googling. (I'm not associated with this site) This was going to be another option, since Ive read that these controllers go bad quite often. shop.championcooling.com/articles/Relay-Wiring

if you replace the fan module replace the fan motor. 95 percent of the time its the fan frying the module. the ford fan motors have an issue with drawing to many amps when starting and running.
