I believe I have a bad connection in the FCM harness of my 2001 TDI Golf. I have the Bentley "Golf Jetta 95-2005" official shop manual.. Where in the section Electrical section.. I cannot find any reference to the FCM (Fan Control Module) or Thermo Switch.. Please send a reference page # if I'm halucinating.

I actually had to rig a switch on my dash to bypass the Thermo Swx to get my fans to run. I swapped out the Thermo Swx in my vehicle into my son's vehicle. Which the same make and year with no problem. Hence, my belief I have a bad connection.

I actually used my milling machine to surgically expose the internal FCM pins. There I can get my compressor to turn on if I jumper out the correct pins. Again a bad connection appears to be the problem.

My problem is finding a good wiring diagram. Can anyone suggest where I can find one? Or a page reference in the Bentley manual in case I've missed something?

Thanks
JQ

I found the Wiring Diagram in the Bentley manual. Will post what I find. I put in a new compressor and had it working. When the fans died. After I replaced the Radiator cooling fans, my Thermo Swx connection went way South.. Will post what I find.
