A/C or Electric problem

[JMVH2]

Last Friday I took the family for a 300+ miles trip Up north; when we were like 50 miles into the trip we stop for lunch, when I got back on the truck and we went back on the road, my A/C was just blowing hot air (out side temp was 97 F) so on the next rest area I stopped and checked what I could with no luck, we decided to go ahead with out the A/C suddenly when I re-started the truck the driver seat moved forward all the way, my mirrors adjusting moved and my TNR did not recognize my CD changer well we arrived to our destination; next morning I tried it and the same thing happened, so I decided to pull all the fuses and relays and re-install them one by one. then I tried starting it up, my seat went back to the normal (programmed) position as well as the mirrors, my TNR recognized my CD changer and most important my A/C compressor was working and it has been since 528 Miles later any idea any one??? BTW I have a new battery (optima) put on 2 1/2 month ago!

Sorry, not anything common. Couldn't tell you more without seeing your truck.

Sounds like something is interfering with the class 2 data bus. A loose connection might cause this.

I'd check all of your connections to the NAV and CD Changer. Beware that sometimes a pin can be "pushed back" inside the connector making a bad or intermittent connection.

Thanks Klaus and Hummertech, I will try that! and if it happens again I will let you know....

I just put mine in the shop for a similar problem. Mine would for no reason just blow out hot air only on the drivers side. If I shut the air off, in time, it would start blowing cold again for a short time. It seemed to do it on both fresh and recirculate.
