Anyone has a write-up or would be able to tell me how to replace a bad ac compressor? I believe mine is dead since whenever I turn on the ac the compressor doesn’t engage and spin. I also tried to add Freon but the system kept overfilling. How hard of a job am I looking at in swapping the ac compressor out with another one? Also is a used one alright to purchase or should I get a whole new piece? Thanks in advance.
