c4 Air Conditioner KaPutt

Hate to interrupt the forum with a comfort question, but has anyone replaced or upgraded their air conditioning and how much did it cost. In my 88 C4 the air has not been used for quite a while and now it is dead. The compressor doesn't even turn and I think it was leaking for some time. Had to keep adding R12 (!@#$%^&*) to the system. Any help or advice will be appreciated.

All systems leak - good ones less than a 1/2 ounce annually, but they still leak. Vettes & GM in particular usually leak at the shaft seal (you'll see compressor oil above the compressor on the hood), or at the evaporator (frost on the windshield is a dead giveaway). You could also have a hole in the condensor, but thats usually a pretty fast leak. Pull the shroud and check between the radiator & the condensor for oil streaks. Refigerent is a matter of choice. The referenced link appears to have been written by a dealer, which seemingly boast the socalled "dropins" the most. For full particulars, go to http://www.epa.gov Most a/c shops will turn down your business if you use anything other than R12 or R134 as they don't have the required equipment to recover anything other than these two refigerents.

I found last year, when I had the same problem, that it was actually cheaper to convert than it was to refill with old gas. They wanted a little over $200 for a full charge of freon, but charged $175 to change it over. Don't regret it at all!

Thanks for the information. I think I 'm gonna check a local AC place and go for the oonversion. R12 is gold in most places and with the 134, I can home wrench if needed.
Thanks again.

I don't know where you live but McJack's Corvette in Santa Ana, CA gets $75 to recharge R12. Did mine.

I'm in Florabama. Was that a complete evacuate and refill? I'd just had a compressor lock up and needed a full refill. Figured $175 for a flush, canister, vacuum, and fill was a good deal anyway. And it will continue to save me money for years to come.
