Hi I have an 86 Rx7 n/a. Did a turbo swap with an 88 turbo II, car runs great. last week my a.c compressor clutch quit engaging. I had the system recharged and put a new compressor, clutch, a.c relay, pressure switch and checked all connections but it still wont engage . The a.c relay will not turn on, I tested it and its not bad whatever turns it on isnt working. I have been spending a few of my weekends messing with it but have gotten knowere. Any input would be greatly appreciated.

 

Did you test and hvac control inside the car ?

 

Did you post in the 2nd Gen (FC) section of the forums about this?

 

Ya i accidently posted in the wrong gen forum.

 

could be the AC switch inside the car.

 

I tested all the a.c electrical. It all seems good except for the a.c relay it has 4 pins and 3 of them are getting power, the other is going to the a.c clutch.
