My wife was putting the car into the garage this evening. I had installed a jump cable on the dryer temp switch to make the aux fan run continuously, so the car was sitting in the driveway.
She pulled the car about 1/2 way into the garage and realized the AC was off. She turned it on and the AC compressor belt squealed and the engine quit. Told her to try starting it and it really did not want to. Turned off the AC and it fired up. Pulled it into the garage and then I started it with the AC off. Reved it up to 2000 RPM and turned on the AC, she didn't like that.
The compressor is toast. I still have the compressor I took off almost 2 years ago. It had not failed. I'll open the system and see if the compressor seized or spit trash into the system. I'll have to flush the high pressure hose and see what comes out. If it is clean ( I hope I hope) then I'll install the other compressor and flush the lines, install a new dryer and see whats up.
Just one of those summer days in Texas. Really start putting a load on the AC and that is when its going to quit on you.

It is a little upsetting that I went through the entire rebuild and the compressor craps out after 1.5 years. it was not a rebuilt It was brand new. But I wonder if the oil lube hole theory applied to this compressor.

Discusses the the oil port issue. I will look at both units and let you know what I find. The new unit (1.5 years old and not a rebuilt) was purchased from ACKITS.com. The old unit was installed at the dealer in 1995 and was a "Mercedes" unit.
