Now I see that the reason it did, was I cycled the headlights. WTH? That's really strange. Found this topic through a google search!

It is weird. My '04 V10 had climate control with no issues. It happened to my a month ago on my 6.0. It was working, but no display. I thought it fixed itself, but I may have cycled the headlights. I thought it had something to do with the rear defrost which I was using for the first time, but I've used it since with no issues.

I believe it's a symptom of a sticking relay that's part of the "power saver" circuit/module - it automatically turns off your interior lights if you keep the door open (for example).
I think it's built in to the back of the dashboard/instrument cluster and not replaceable separately - hence the cycle the headlight trick to force more power through the relay to wake it up.

Yep, it's magic.

This happened twice to me, 05 6.0.
The first time last week I cycled the key and it then worked.
Then just now, key cycling did nothing.
Both times everything did not work, not just the display.
I Googled it, came here and cycled the headlight switch and that worked.....
Voodoo is right!
Thanks guys,
Joe

Mine will not work in the winter when it is cold. Neither will the adjustable pedals. Cycling the headlights will not work, however taking a hairdryer and warming up the climate control face/buttons seems to do it for me.
I leave it on defrost/floor all winter, only have to use the hairdryer trick when someone turns it off. The steering wheel controls allow me to adjust the heat and fan speed regardless of how cold it is. Once the truck warms up everything works fine.
Texas truck can't take the -20 to -30 F temps I guess.

I've had my 05 powerstroke since March, this has happened to me three times. I start the truck and it's dead.... If I shut it off, go into a store and come back it's fine. The only common thing I've seen happen so far is that it only happens if the truck was started and then shut off quickly, like the car wash, or if I stop to top off the fuel tank. It's never happened while driving. Next time it happens I will try the headlight trick. I run with the AC on almost all the time. It happened today but this time while I was driving with it "dead" I experienced a stumbling almost stalling when I accelerated from a light. I was unable to recreate this and it only happened once. Scared the crap out of me, aside from this the truck runs like a raped ape, bone stock. If the headlight trick works I'll add my findings to the thread.
