Alright, I think the compressor is on its way out, but i need to be sure. #1 cooling on this thing sucks azz.... if i drive it for longer than 40 minutes the AC start blowing "warm" air compared to its not so cool air. I figured the buzzing has something to do with it, i only hear it from inside the car which leads me to believe its some type of vibration caused by the possibly bad compressor. turn off ac and just use fan, no buzzing. I thought the blowing hot was due to low AC freon, but i checked the low side and it was at 90PSI which to my understanding is stupid high.

Anyways my plan is to rip out the old compressor and swap it out with a new one (or another model that works better and is a direct fit- Opinions?) and have the system recharged and hope for the best.

Any assistance would be greatly appreciated!

TIA

Buzzing inside the car is more likely to be a blower motor than an A/C compressor issue. 90 PSI on the low side typically means that the compressor isn't running and with it working for 40 minutes before stopping, I would lean towards an electrical or A/C clutch issue.

I thought the buzzing was blower motor, but if i turn off the compressor the buzzing stops, it also increases as the engine revs, and as for the compressor not running as im measuring the low side, i can see the compressor is in fact engaged not just the pully.

Now that is really strange. What is your high side pressure? If it is a compressure failure then you will have to do far more than just replace the compressor. All of the lines will have to be flushed, the condenser and evaporator will have to be either flushed or replaced, expansion valve and dryer will have to be replaced, and new refrigerant oil added before the system can even be refilled.

yeah, I found a compressor that will fit that is more efficient, and found all the components to replace it too, prefilled with the correct amount of oil and desiccant so should be good and a dryer all for about 300 from Rock auto, then some local mechanic (certified of course) will install and recharge for 600. not bad for a complete system replacement.
