It's an 04 CE with manual trans, and about 100 K miles. It has stopped blowing cold air, just blows ambient. The compressor would run initially for a minute or two before, but now is not cycling at all. I do see a jump from 800 to 1000 RPM when I push in the AC button, which will then drop back to a little higher level, 900 RPM, as long as the button is left in. This must be the computer control, as The compressor is NOT turning. I put my R-134 gauge set on it, and it shows 60 psi on high side, and abt 55 on low side. I guess this is just gauge error, and both sides are equal, I looked at the data stickers on the car, but did not find one showing the service charge. My Haynes manual also does not give any charging specs. I tried to add a little Arctic Freeze with oil and leak sealer to the low side, but although the valves are open, none would go in. I guess that is what would happen when you still have this much system pressure? If this is what system pressures you would expect when the compressor not running, then I need to look at the compressor electrical controls, I guess?
