Hello, everyone! I'm a new user here and was hoping I could get some help with an A/C issue I'm having. I've got a 2001 Xterra that will only blow cold on occasion. The lights for the A/C on the panel come on and the blower seems to be working, but most of the time it's warm air. I went out and bought one of the recharge kits and when I used the gauge to check the pressure, it was at 150psi...three times what the can recommended. What would cause such high pressure on this port? I'd consider myself to be pretty handy with cars, but I've never tackled anything dealing with the A/C. Any suggestions or comments? Thanks for taking the time to read this and I would appreciate any feedback given!
