I've got a 1990 Spider Graduate (S3 body, S4 mechanicals). Lately I've noticed that both of the electric radiator cooling fans run nonstop while the car is running, from the time I start it to the time I turn it off.
I did some troubleshooting, with the following findings:
- I unplugged the wire to the passenger-side fan. Both fans still run.
- I unplugged the wire to the driver's side fan (goes into the frame). Driver's side fan stops. Passenger side still runs.
- I removed the relay on the fuse panel and both fans don't run. Engine predictably runs hot.
The car has an A/C switch and temp rheostat on the console but I never use it and I suspect the compressor won't even start given the car's age.
Is the relay stuck closed? What am I missing?
Thanks for any help.
