Hey all,
I have a 91 Civic DX, and I recently went to a local shop to get the AC system charged since there's a slow leak somewhere (charged it two years ago at a different place and I had no cold air the year after). They asked me if I wanted to convert it to r134a since r12 is "about $200 per pound" and the conversion plus charge was under $300. I figured it would be worth it since I heard about the whole "oh no r12 is ruining the ozone," so I had them do all that, and when I got it back the blower was pushing hot air even with it turned all the way to cold. Figuring the heater switch was stuck on, I bypassed it completely by moving a hose and now it's just blowing air-temperature air. No chill yet.
I checked to see if the compressor was engaging at all and it wasn't. I noticed that a bypass wire I installed about two years ago came loose as soon as it was touched, so I reconnected that and tested again. Still nothing. I checked the wire and it was getting current. I even bypassed that by hooking the compressor straight to the battery and it *worked, but it wasn't really blowing any cold air. I'm thinking that a relay went bad somewhere, but I can't find the darn thing. I looked in and around both the fuse boxes and I can't see anything that looks like a relay. Does anyone have a picture or can describe where this would be, or is it something different? Maybe the guys at the shop screwed something up with the refrigerant for all I know. Thanks in advance.
Edit: changed wording at asterisk because I was very vague before.
Another edit: It turns out the gaskets that were changed were put on loosely so all the coolant blew out almost right away, which prevented the compressor from spinning. I had them changed again, but it seems that the coolant blew out AGAIN. I'm wondering if the leak is bigger than I originally thought.
