I have a 1988 Convertible RX7 and the A/C clutch isn't engaging. I replaced the A/C control module in the dash. I even put a jumper wire on the clutch to give it 12 volts and it worked. So I know that it's ok. Is there a fuse anywhere or a relay I can check?

 

Get an FSM and follow the wiring diagram.

 

Do you have refrigerant in your car?

 

also might want to replace the pressure sensor, or check to see if it's working/connected/there...

 

You can check the fuse panel-https://www.rx7club.com/attachment.p...hmentid=219918 Room fuse blown will keep it from working.

You should try jumping across the switch on/near the drier-it has a low pressure cut-out function. Pull the plug and jump between the terminals on that plug. If you jump across plug and the compressor runs, you are low on refrigerant.

There is a main relay up in front just behind the bumper-look in the FSM for the location but it should be the closest relay to the hood release latch on the driver side.

+1, probably low/no charge. Get a set of A/C gauges and hook them up, usually ~20psi is the limit for the low pressure switch.

 

I thought it was the cigar fuse?
