So, my A/C hasn't been blowing cold air for quite some time now. I realized that the compressor clutch isn't engaging at all, and that the compressor clutch fuse is blown. I've already traced the harness coming from the compressor all the way to the back of the engine bay and didn't notice any chafed wires or anything else unusual. Where should I begin looking for a short? I don't plan to take it to a shop because I can live without A/C and I'm cheap lol.
Thanks

if your out of refrigerant the a/c clutch wont turn on, best bet is to go to shop and have it tested out there, unless you have a a/c vac and gauges for a/c.
or you could do what most of the time costs more, and buy a can of the leak detector refrigerant, fill the system and look for the leak via the dye, and fix what ever is leaking.
on a side note letting used refrigerant into the air is BAD, and you dont want to do that, the shop can vac out the old stuff and reuse its so its like paying the same because you keep having to buy new refrigerant when you let it go in the air, or pay the shop, either way it will wind up being close to the same price.

I forgot to mention that I already bought dye and found no leaks in the system. Even if my refrigerant is low, that doesn't explain why the fuse keeps blowing, does it?

i have the same problem i replaced the orifice tube and accumulator last night and had it vaccumed and recharged today but the compressor would kick on. i cheched the fuse and it was blone. i put a new one in and it blew right when i turnd it on. it might be that the cluch is fried and you have to replace the whole compressor.
a way to check and see if its blowing before it even gets to the compressor is grab a jump box and hook up wires the the pos and neg clips. unplug the wires to the compressor and put the wires from your jump box to the two posts on the compressor. if the cluch is engaging. if it is you know it electical. if it doesnt than its the compessor. not the safest way but its a way to find out what side the problem is on. i will be doing it soon to see what the problem is with mine.
keep me posted i would like to know whats up with mine too

Okay, that makes sense, but I'm not sure that I'm comfortable using a jump box on my compressor. Can anyone else chime in and give me some re-assurance?
Thanks

i did it to it before and didnt have any problems. the low pressure switch wouldnt let it kick on. so before i did any work to it i wanted to make sure the compressor was still good and i jumped it. the thing kicked right on and worked so shut off the jump box its all 12volt so it cant hurt it
