    Fuses look good, light comes on when A/C button is pressed, when I unhook pressure switch, I get a climate control maintenance fault so I assume that switch is working and I have proper pressure.
    Any thoughts?
    Thanks.

    If you have good pressure and everything else checks out good big common problem with these things changed tons..... change the low pressure switch should be just above the air filter above under the hood cowling along the firewall on the fatter low pressure line the sensors only 90 bucks start there
