I have a 1996 Jetta. If you have the older body style then it is directly beneath the round coolant expansion tank, attached to the strut tower. It is a black rectangular box with fuses under a clear plastic cover. You'll need to unscrew the coolant expansion tank to get at the fan control module. It is susceptible to being doused with coolant which might cause the fan control module to short.
There is a magnetic (solenoid) clutch inside the air con. conpressor, there is also a fan control switching unit that turns on the cooling fans and the air con. clutch according to a bunch of other sensors that it (fan control switching unit) is conected to. Attached under the battery box. This is how it is on a Bora with Climatronic air con, may be the same on a jetta, but simplified on a non Climatronic system.
The fan fuses are located besides cooling reservoir
The Volkswagen Jetta uses an ECM instead of a stand alone fan relay. The ECM has to be changes as a single unit.
2002 vw jetta-temperature light goes to red in 30 seconds. any opinion will be appreciated.
The fan control module is inside the main (larger/left) fan motor. It requires replacement of the entire fan. Your secondary fan may still work. Bench test it to confirm.
it does not have a relay for the fans. they are controlled by the fan control module located underneath the driver side frame rail.
Under the coolant bin, on the right top side of the hood.
Idk. I replaced the thermal sensor on mine I also have a 98 jetta didn't work. So it's either the fan switch or the control module fan relay.
no switch,fan control is determined by the engine control unit with input from the coolant sensor
If you mean the radiator fan make sure the airconditioning is off. If the fan keeps running it could be a bad fanswitch (located on radiator tank. Or a failed control relay (if fitted) If still no luck check for a failed AC fan control relay.
yes , this is controling the fans and ac fans
Check your Fan Control Module!!! Check your Fan Control Module!!!
