Climate Control Question
Need some A/C advice. I'm leaking freon somewhere. Had the system recharged with dye. Shop I took it too thought it was leaking from schraeder valve so they replaced both valves, put it on a vacuum for 30 minutes and it held pressure.
About a month later and it's low again. Can't see leaks anywhere using UV light. Could the compressor be leaking internally in a way that you can't see the dye? I guess the other option would be the evaporator but I don't smell anything in the cabin. That and the fact it held vacuum makes me think it's leaking only when compressor is running.
Any ideas? Am I missing something obvious?
