I have a 2000 tt. Fans run after ignition is off until battery is dead.

I pulled the connection from the temperature switch on the radiator and the fans keep running.

I can't find any information on the location of the fan relay so I was wondering if the fan relay is the fan control module that is located under the battery.

Thanks in advance.

 

actual they call it auxiliary fan controller and yes it is under the battery a 16 pin 4 pin hunk of junk that goes out on every vw & audi years 2000-2003 if not more. replace coolant temp. sensor with the new(old now) green one. but the one fan generally runs after turning the ignition as a cool down it will be the smaller one on the passenger side but if it keeps running and taking the battery out that is wrong check fuse # 16

also check your battery at top here is a pic.....


this might help as well trying to organize DIY http://whanab.com/

 

Thanks ND.

Both of the fans ran until battery died, and at high speed. I pulled the control module last night and banged on it to see if I could get the relay to open and it did not.

New module on the way.

Appreciate the input.

 

No problem each fan connect at the bottom of the fan shroud by bottom hose of radiator just above that make sure their tightly secure as well.

L8R......

 

I need further help.

I replaced the fan control module. Drove car and it the temp gauge went way beyond the mid point once warmed up. I opened the hood and neither fan was working.

Every fuse on the panel was checked as were the 3 fuses in the box above the battery.

I then replaced the fan switch on the radiator, ran the car until the temp gauge once again went well past the mid point and still no fans.

I then opened up the old fan control module to inspect the relays and found a badly burned set of relay points. Cleaned the points and re-installed the module without the cover so I could manually work the points. When I closed the set of burned points both fans operated at the higher speed.

I need to understand what is missing in the circuit that provides power to the fan control module other than the fan switch on the radiator. Something is keeping the fan circuit in the module from getting power.

Any help on this would be greatly appreciated.

 

I could really use a little help on this. Surely someone else has had this problem.

Maybe someone has a wiring diagram for the fan circuit??

Thanks in advance.
