The guy at Autozone scanned my codes and one of them was P1641. He looked in his little book and it came up as - Manufacturer Control Auxillary Inputs Auxillary Outputs.
Thats a new one for me, What does that mean?

P1641 Fan Control (FC) relay 1 control circuit
Time to check out teh fan system. do you have a manual switch or done anything with the fans? you can test for 2 power siganls at teh fan relay one. if your lacking 1 or both you need to check the fuse and fuse link. you can try swaping the relay out. the other thig woud be the ground signal from the computer to close the relay. if your ac is working start the car and turn it on. the fans should be signaled on and you cna then test for the ground at the relay on the dark green wire
