2004 Infiniti QX56 Question: A/C High Prssure switch



overdalimit, Baton Rouge, LA, August 04, 2009, 17:17

My A/C has not been coming on intermittently. When I unplug the high pressure switch and plug it back in the compressor starts. It cools great and then the compressor will cut out agian. Any ideas?

    Sounds like an issue with the high pressure sensor or the A/C pressure is too high. Better put some gauges on your system and make sure your A/C is not running to high. If the pressures are OK, then replace the switch. Good Luck!
