Climate Controls Gone

[jonylost]

Got in the Ex yesterday, cranked it up (starts and runs great) and reached down to adjust the temp and turn on the AC and ......... blank. Pushed every button on it and no dice.

No circulating fan, no AC up front. Nothing else in the vehicle seems to be affected

I looked at the fuse box and there is nothing reading AC or climate control or something like that.............what do you all think? Any ideas?

Push the ext temp button. If that doesnt work check the connection in the back of the unit

cycle the head light switch from auto to on back to auto with the truck running. my x and 05 have done that a few times and it kicks it right back on.

Mine did that on the weekend, I just shut it off then re-started it and it worked like there was nothing ever wrong (I may have pressed the ext temp switch in there somewhere).

My 2005 just did the same thing. Turned the truck on and off and it came right back.

Turn the headlights on and back off, works everytime.

No doubt, but it works. I thought oh no! Another $1000 repair, but my wife looked it up on her phone while I was driving and sure enough, I flipped it from "auto" to "off" and the darn air started flowing!

Weird? I wish someone will tell us the permenant fix, but it seems to be software related...

I have had the same problem. It seems to happen during the hottest days. I found that if when starting the engine turn the ignition switch to run piston and wait for door locks to lock then hit start. It seems to keep the software glitch from happening. If your system decides to not work then I found that you need to re-boot the whole system by shutting down and getting out of vehicle close door and lock it. Then reenter and start whole sequence over again but wait till door locks lock then hit start. This has worked every time for me.

Count me in too. Good to know the headlight trick. I always have to stop and turn he key off and on a few times to get it to come back on.
