I have searched and searched but can not find any info on a similar situation to mine.
AC has not been working since I bought the car about 2 years ago.
Yesterday I replaced my AC o rings and recharged the system. The O rings were not perfect size but matched close. After adding two cans of r134a to the system (Blindly, no gauges) it blew cold and the compressor engaged fine, but shortly one of the o rings leaked.
Today I replaced with factory size o rings, vacuumed the system, it held vacuum fine, and recharged with one and a half 12 oz cans of r134a which took the pressure gauges right to where they should be from my research (25-30 psi low side and 230-240 psi high side)
Perfect pressure values but no cold air today, even though the compressor was working yesterday. I have checked the fuse and relay both and found no issues. The compressor clutch tries to engage every 5-10 seconds but simply catches and immediately releases.
Could it be the expansion valve stuck closed or a pressure sensor issue with my current symptoms? How can I test?
Can anyone recommend next steps for troubleshooting?
