It's hot. I've actually got two questions.
First my 95 has been sitting a while. I noticed that when I go to use the air conditioning- it doesn't engage. I can turn the compressor clutch and when I hooked up a gauge to the low side service port, it looked like it was a low charge like 20-25psi.
Think I should hit it up with a fresh 8oz charge of 134a and see if the A/C starts working again? Any special precautions? What should I look for?
Second on my other "SC" (Saturn) I converted it from R12 to R134a. I did that at the end of last summer and I added about 18oz of 134a and 4oz of Ester/stop leak stuff. It seemed to work fine for a week but then I stopped using the A/C (cause the weather cooled off).
Today in the scorching heat, I went to use the A/C and it kicks the compressor in but there is no cooling. Hmmm. I hooked the guage up to the low side port and it indicated that the system was way overcharged, something like 75psi.
decided to vent some out and brought it back down to about 40psi but the A/C never got cold at all. Compressor was still turning, so I thought I should let off more and brought it down to 25 psi and now the compressor stopped turning (probably too little pressure). I'm stumped? Maybe I added too much oil? Any ideas?
