Question about 2002 Volkswagen Jetta TDI
My AC on my 2002 jetta does not work. The compressor does not come on. I tried to add refrigerant and compressor still did not come on. I am guessing it is and electrical problem of some sort. I have also replaced the AC pressure switch. My coolant fan also runs after car is cut off for about 30 min. even if engine is cold. Both of these conditions started about the same time. I noticed the fan running after car was turned off in winter and that next summer AC was inop. Thanks for any information.

fans and modules are kind easy to do but you will have to find someone in your area to do them... you might state what town and state yopu are in so people know.

Yes it is that easy. It should be a 4 pin connector located on the transmission side of the engine head in a plastic flange. Best is to wait for the engine to be cold. Unscew the radiator cap to relieve pressure but screw it right back on. On the 2.0L engines when you unclip the coolant sensor little or not coolant loss will happen if you do this. Just unplug it, pull out the clip, pull out the sensor, and the seal which sometimes stays stuck. Install the new sensor with a new seal lubricated with some coolant, make sure it's well seated and reinstall the clip. The sensor is well seated if the clip fits right over the top, just make sure both sides clipped into position. Replug it fill the coolant with VW original coolant mixed 50-50 with water if needed and done. If you have a fault you might need a scanner to erase the check engine or fault in the cluster.
What's the reason for changing it? Eratic temperature readings?

TO CHECK OR ADD TRANSMISSION FLUID TO JETTA IT HAS TO BE BROUGHT IN TO A VOLKSWAGON DEALEALER THERE IS NO DIP STICK EVERYTHING IS SEALED SO ONLY THE MECHANIC CAN CHECK IT.
