AC stopped, then worked....WFT
Anyone else with an F250 have their AC just stop working? Then start the truck again and it comes back on?
I did a search for the problem but didn't see anything similar.
The situation: I went to a buddy's to drop something off, AC worked fine. Left his house and went to the store for a can of cope. When I came out, fired up the PDS, no AC. Screen blank, buttons didn't work...nothing. I called Ford to ask if the AC had a separate fuse...he said if my radio was working it was something in the unit itself and to bring it in. I setup an apt for Monday Morning. So.......
I get home no AC still and pull in the garage. Get out my ol SCT and put the truck back in to stock. Guess what? AC turns on while loading stock tune.
After the load, I tuned on the truck and went around the block, AC worked fine.
Is this strange or what?

Going to go reload it and see what happens.

EDIT : Loaded the tune back in and it worked. Hope it was just a fluke.

RollingRock,
It's a "feature".
The 2nd time mine did it I figured out how to fix it accidentally. It's done it 3-4 times total in over 3 years.
Next time it does it, turn the headlight switch on, then off. You have the Auto-lamps (it's the ones that do it) so turn them on and off manually. Climate Control come right back on. Turning the headlights on and off triggers, or kicks a lazy relay somehow.
It has something to do with a lazy general electrical relay, or something along those lines. There's supposed to be a TSB out now but I don't know if they have fixed the relay or whatever it is.
