So, for the past few years my A/C has not worked, and I have just dealt with it as I figured a compressor was a lot of time and $$. Due to a renewed interest in getting the ol' girl back up to snuff, I started digging around and checking things.
Symptoms: No a/c, no small fan running. Engine idles up when a/c is on, but no results.
Checked the freon levels and found them to be satisfactory. Checked the fuses and see no issue there. That got me to wanting to check the solenoid, but due to the angle of the plug, it is a pita to get to test it. I was doing some searching and found that the a/c pressure switch could be at fault. This component being bad would explain why neither the fan, nor the compressor work. As opposed to both of those parts being bad. So after the long winded explanation, does anyone know if removing this part while the a/c system is still pressurized will cause a total pressurization loss, or does it need to be vacuumed first before it is removed? It looks as if it simply screws off of a schrader valve, but I would rather be sure than release a crap ton of freon into the air on accident. Thanks!
