AC

May 03, 2004 4 Replies

The AC compressor wouldn't come on in my 97 Cherokee Sport. I added 2 cans of r134a with sealant. The compressor came on and the AC got very cold, but I could smell this smell like alcohol inside the car. The next day I tried the AC again, and the compressor wouldn't start. I pressed the low side Schrader valve, and not even a "pfft". I guess the system is empty again. I didn't see any evidence of that green sealant at any hose couplings, condensed, accumulator etc. I have heard that the evaporator cores are common to go bad and the fact that I smelled something in the car could point to that. Any thoughts?

More than likely.

Sure sounds like you nailed it. Before you disassemble the whole dash to get at that sucker, I would invest in having someone run a sniffer around with a little R134 in the system just to localize the real leak

- I've seen some sneaky freon leaks that even the floresent red dye didn't mark, especially around hose connections.

Or just put some air pressure on it (if it is leaking, it is 'probably' already contaminated) and listen for the leak.
