Well, from my short ownership of a 79, L-82, I am finding that vettes have certain "known" issues. Well, good that those of you out there know some of these and I hope you can tell me what to look for. I dont need, but I want my Air Cond fixed. I decided to take a class at local J. College. Figured it was just as cheap, get to do it myself and learn something in the mean time. So. Who knows any specific issues with the Air Cond that I need to address or check out while I am getting this thing fixed? Or is the AC just like any other and need to just do the job right the first time. All the parts are there. It appears that there is no freon in it. Dont know what else is wrong. Maybe it is just a leak. I am thinking about putting in R-134. Ok, let me have it!!!
