No power going to the compressor. The fan runs and the air conditioner switch lights. Checked freon and it is ok.

I have the exact same problem with the wifes car, same year and all. Everything else works ( fan light on button, and all the fuses are fine), except there is no power going to the compressor. I can run a jumper wire from the battery to the compressor and the ac works great but I cannot leave it that way because it will not cycle and I do not want to over pressure the system.

I figured it out, the problem is the relay under the hood in the fuse/relay box on the driver side fender. The MG/coolant relay is bad. Go to Advanced Auto and they have the relay for $14 it will be under A/C components in their computer, they will have to order it, but it will fix your problem.

Hope that helps you

Just to add, there is a service bulletin, About that relay. It says to only use part# 90987-02028. Relays with other part #, are not to be used for this application. You may have to get that part# from dealership. I'm only repeating what the service bulletin had to say, if you used another relay and it worked great, that is fine with me. Have a good day.
