Air Conditionig Repair--where to start?
Ok,i have a 78 GMC,and it has Air on it,but its not working right now. Where do i start and what do i look for as far as figuring out what works and what my problems are? I know one of the a/c hoses has duct tape on it,so im almost positive it has a hole in it and needs to be replaced. Since there is only 3 a/c lines that i see,i thought of just replaceing those to start with. I have a 350 with auto. tranny. Any help is appreciatted.

Yes, replace hoses and condenser, have it evacuated, charged, and see if it holds charge. Condenser needs replacing due to excess moisture from leaks. I spent around 200.00 on hoses, condenser, charging, etc. My compressor is working fine.

If you are staying with R-12, then do as Joe said above. You will probably need a new compressor. If you are going to switch to R-134a then you will need all of the above plus a new orifice tube, high pressure cutoff, a really good flush. Don't forget to get new o-rings!

I chose not to convert due to having a supply of R12 available. Once I run out, I'll be forced to, or check classified ads. As far as servicing? I've never had a problem... One thing I've received from LMC that was good quality/price was their replacement hoses. When my compressor goes, I'll switch. apstguy makes good point, probably right time for you to switch over $ permitting.
