AC Nothing At Switch ???
The AC system in my 1993 GMC 1500 V6 is all new.
Was working just fine two days ago but last night I hit the blue AC button and I get NOTHING. Switch? Relay? Which one? Thanks |

If its a relay, the one for the fuel pump should be the same. You can swap them to test.

Jump out the high pressure switch. You could have lost pressure and system won't come on.

OK
Just for the heck of it I just went out and randomly pushed buttons on the heat/AC/fan control panel and, guess what, the AC kicked on. Strong and cold as ever... Ideas? |

Bad solder joint somewhere? Loose connector? Pull out the control panel and check for loose wires, bad ground, etc.
