1999 Honda Civic. The compressor is a used one I installed a few years ago. The A/C has been working fine but after a drive, parking, and shopping it was blowing hot air. The compressor clutch was not spinning. Later, at home, after cooling down a while, the clutch did engage and the system blew cold air. The state of charge was OK, according to the gauge on an empty recharge canister I had kept.
I think the compressor thermal protector circuit was open until the car sat at home and cooled down a bit.
Is that thermal protector malfunctioning (how can it be tested, what is its open/closed temperature spec)?
Is the compressor actually overheating (why does that happen)?
What harm if I bypass that thermal protector (I’ll need another compressor anyway, if this one is overheating.) If it siezes up I’ll have to remove or cut the belt. On this car that belt is only for the compressor.
