Need help figuring out this problem with my air conditioning and I’m trying not to break the bank. My car stopped blowing cold air, I found the compressor was not engaging pressures were high and so I ended up replacing the compressor recharging correctly and it worked for a day then the same thing. Repeated the same exact process two more times with new compressors with the same results. Replaced the expansion valve, and condenser and still no luck. The system holds vacuum (I let sit for 2 days and no change in pressure). I cannot figure out what the issue is! Please help!
