I replaced the AC unit on my 01 TDI then the fans. However, I noticed that when I attempted to run the fans, they would spin momentarily. Then they would shut off. I followed the procedure in the Bentley Shop Manual. It pointed at the Thermo swx. Because I could jumper out the thermo swx and the fans / fans would run. But, my son has an 01 TDI too. The offending thermo swx in my vehicle worked fine in his. I also swapped out the FCM's to no avail.

I have a FCM that I cut access holes with my milling machine to expose the connections. I can jumper out pins in the FCM and get my AC / fans to run.

I've installed a manual swx and bypassed the thermo swx. To get the fans to operate.

Any suggestions?

Meter it and see where you are losing power. And perhaps spend more time on repairs than bastardizations . . .
