Trouble with my A/C
I have a 2005 ZX4, and the A/C was working but not very well. I put my gauge on the low pressure side with the car off, and it read 120 psi. I know you're not supposed to do this, but I vented that off to the atmosphere till it was nearly zero. Then I started the car and added R134a until the pressure was around 35 psi. The compressor will not run, but I'm not comfortable adding more refrigerant until I find out for sure what the pressures are supposed to be. I'm thinking I'll cut my losses and take it to a professional, but if there's an easy fix that's jumping out at you, I'd sure love to hear it. Thanks!
