My AC quit working at the end of summer. For a while, the compressor cycled on and off constantly -- 2 seconds on, 2 seconds off -- over and over and didn't cool well. Now, the compressor won't activate at all (it tries for a split second the first time after the car has been sitting, but it immediately cuts out )
I suspected a leak. When I started poking around, I noticed that the high and low pressure ports are the R134 style. The Sanden compressor appears to be original, and it clearly says "R12" on the label.
I have some service history from a prior owner -- there was a lot of AC work done around 2003 with some new hoses (can't tell which) and a new condenser. One of the invoices specifically says "Freeze 12" which, if correct, means it was still R12 at that point.
How do I have R134 ports with an R12 compressor, or is that a normal thing to end up with over the years? And is there any way to know for sure what refrigerant is in there?
Thanks for your help on my first-ever post!
