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 Volkswagen Jetta uses an ECM instead of a stand alone fan relay. The ECM has to be changes as a single unit.

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.
