I have a 1997 Honda Accord LE, 4 cyl engine. The A/C is not working. I have checked the A/C charge and it is good, and I have checked that the compressor clutch can engage and it does. There seems to be a problem with the compressor relay. There is power going to two terminals and two terminals that are not powered. One of the non-powered terminals goes to the clutch (I assume that when the relay closes, then the clutch receives power). The other non-powered terminal is a red/blue wire that, according to my wiring diagram, goes to the engine/power train control module. Does this module control the A/C as well as the other things it is named for? When I ground this particular terminal, then the relay will close and I get power to the clutch. I hope this doesn't mean I have a bad computer module. Could a bad relay act this way?
