try pulling S19, 30 amp fuse. if nothing, try Fuse S4. if nothing, follow wire from fan to temp sensor and pull plug there. could be caused by shorted wiring. Also, there is a relay directly under the coolant expansion tank and if it's getting coolant spilled on it, that could be your "short".

How to test cooling fan control module vw jetta 2001

The cooling fan module is located below the radiator over flow tank. The discharge from the overflow tank discharges hot collant directly onto the module. Every time mine stops working we take the two wiring harness plugs off and find coolant inside the plugs...(we had to use a set of brake spring plyers to get the large plug to snap back into place) I'm gonna move the cooling module and associated wires n plugs out from under the overflow tank - dry everything off (for the third time) and see if this solves the problem.

I have a 2001 jetta ac clutch not engaging freon pressure levels read good by pass compressor its cools good.

Check to see if the wires on the fan module are corroded. The fan module is under the battery. Easier to see from under vehicle. Also check the fuses first.

Cooling fan not working

check if the fans work by putting a jumper wires to it, unplug the fans and get two thin wires attach one to a ground then to the other one to a power source touch the terminal be very careful the fans will come on if they work. If they do work then you have to unplug your temp sensor if the fans click on that's your problem. The car has to be warm up first then turn it off but leave the ignition on. If that doesn't work its your fan relay or a bad wire

Cooling fan on 1.8 turbo VW Jetta 20001 did not shut off all night after car was turned off

Locate your rad fan relay, and next time it does it, give it a quick rap with handle of screwdriver or similar weapon. If it stops, replace relay.

Cooling fans, radiator fans do not work anymore

Yes, there should be a fan motor. There should be a wiring harness in the middle of the fan assembly. This is the power for the fan motor.

2005 vw jetta radiator cooling fan wont shut off

Check for a switch at lower part of rad. Should see a wire harness & plug on a sensor at bottom of rad. This sensor/switch also operates fan on/off according to coolant temperature. You may need to disconnect battery to get at it safely.
