Maybe I missed it. I read it as it was locked up after sitting. I'm not clear on that, either. OP, did the compressor seize after you ran it a while and after the six-month hiatus or was it locked up immediately on starting the engine? I noticed in one view that the pictured compressor has a 1/4&qu...

All was working fine on the A/C and then I ended up letting the vehicle sit for 6 months. I then got the vehicle running again. I then attempted to run the A/C but ...

From what I understand, there has to be enough charge for oil to circulate through the system. If that is true, what keeps a pump lubricated when the system is being re-charged? When I was re-charging the system after replacing the condenser, the compressor was sucking in the freon slower than molas...

After removing the compressor that locked up, is there a way to tell whether or not it sent debris throughout the system? I had just installed a new condenser and I'm hoping I don't have to replace it again.

I installed a new A/C compressor in my truck about a year ago. Unfortunately, the cooling performance was much reduced compared to the original compressor. Today, I installed a new parallel flow condenser hoping that I could get better cooling performance. As I was charging up the system and cold ai...
