Help me diagnose my AC problems
Air comes out of the vents, but it's warm air. What should I do to find out what the problem is/how to fix it? Are there any websites that can help me with this? I am using the old r12 freon.
thanks

Re: Help me diagnose my AC problems (marthpodi)
The first thing to do is see is the clutch on the compressor kicks in, which it probably isn't. This probably due to being low on freon charge, the low pressure control has probably taken it out of the circut, low charge is the most common problem due to leaks in the system. You probably have an R-12 system, you can tell if it been converted by a sticker (usally blue) in the engine compartment stating so. Another way you can tell is by looking at your accumulator, it will have quick-connecting fittings if it is R-134 or have the schrader fittings if it is R-12. It costs some bucks to get it converted, I belive they sell do it yourself kits though. :chevy

Somewhere your AC system is leaking freon. You need to get the system recharged and have them add dye to it. Then run the AC for a few weeks and take it back to the garage that recharged it. They can then use a black light under the hood to tell you where your leak is.
