It's fine now??

I have the fan relay out and I can operate the fan with the A/C switch. The A/C fan doesn't come on anymore either.

I love this car :beats head

It looks like in the early models it was wired that way. It would allow the fan to run if the car was very hot when shut down.

I removed the A/C condenser and fan this past weekend. The problem is now gone. I believe it was due to the sensor on the condenser since with that unplugged, the problem stopped.
