SmashedGlass Posted July 26, 2014 Share Posted July 26, 2014 Okay, system was fully done and retrofitted to R-134A by a professional shop, and works great------if the compressor has voltage applied direct. Cycles on/off, blows cold, car idles up, everything. I have bypassed the belt protection system, I have checked the a/c and fan relays (good), pressure switch works (see cycle on/off) even jumpered the micro-switch under the drivers side dash, all to no avail. I'm at a loss as to why it isn't working normally. Ideas? Quote Link to comment Share on other sites More sharing options...
Loyale 2.7 Turbo Posted July 26, 2014 Share Posted July 26, 2014 (edited) Assuming that your car is an EA82, (There is not enough background info) Yes, look for a Worn "Main" A/C Relay, under the Dashboard, up above the internal Fusebox Area. More info & Photos, here: ~► http://www.ultimatesubaru.org/forum/topic/87523-how-to-swap-the-old-roundie-relays-with-standard-bosch-relays/ That relay sends the Power signal to the Two relays outside, on the engine's bay, for the Fan and the A/C Clutch. Kind Regards. Edited July 26, 2014 by Loyale 2.7 Turbo Quote Link to comment Share on other sites More sharing options...
SmashedGlass Posted July 27, 2014 Author Share Posted July 27, 2014 Thanks Jeszek, I was thinking about that relay too, just dreading trying to get to it. For now I have a toggle switch wired in to the blue and blue/yellow wires on the main a/c relay so I can have air. 1 Quote Link to comment Share on other sites More sharing options...
