my AC comes on, it cools well when car in on the highway . so then I checked and the condenser coil fan does not work. the fan that is behind the engines radiator and the AC coil (condenser) . I connected straight from battery and the fan works. can some one send me the AC wiring diagram to trace the wires back to the AC relay thank you so much in advance.

Thanks for visiting 2CarPros.

I'll post the diagram below. This is a two speed fan so there is a high and low speed relay. The fan should kick in when the high pressure side is at around 300-350 psi. if the wiring and relays check out it's most likely an issue with the pressure switch.
