Is there anything electrical that could cause the AC compressor to not engage?
AC worked fine all summer. Has worked fine for 3-4 summers. It worked fine today. Drove somewhere, parked...shut the car off then remembered I didn't turn off the AC so I switched the knob to the off position with the car off. I don't like starting the car with the AC on. Went in to the BBQ, came out tonight and started the car and turned on the AC and nothing. The compressor doesn't come on.
I had a problem last year with the fan relay's popping due to old/worn out fans. I replaced the fans and the relay(s) and haven't had a problem since. I don't remember exactly but I'm pretty sure the AC did work even with a burned out fan relay. Just the car would overheat very fast in traffic.
So, it's gonna be in the 90's again this week and my mechanic is closed for vacation so I'm hoping it could be a fuse or relay or something I can fix easily by myself. I've had a catastrophic failure of the compressor before and the instant discharge of refrigerant was quite dramatic. That definitely did not happen. Though I'm afraid the headers might have finally burned a pinhole in the ac lines and the system just slowly discharged while parked today. AC lines are bent away from the headers for clearance and wrapped in that heat wrap material. But still that seems the most obvious problem.
