2006 F250 electronic climate control unit not working

NEED: wiring diagram (pin out) of the 2 plugs going to the climate control unit. Thanks!

The unit is not working at all. Nothing lights up. I've searched & found others with this problem who were able to reset the unit by tuning the head light switch from (off to auto & then to the on position) while the truck is running which seems to help them.

I've also checked the 20 amp fuse under the steering wheel which isn't blown.

I'm now to the point of checking to see if there is any power going to the unit with a light tester and if there is power, then it must be the unit itself.

I have a 2006 F250 Lariat with about 25,000 miles. Mainly used for towing the race car.

Any input is appreciated. Thanks everyone!

Mine has randomly done this. Start the truck it wont turn on. Shut the truck off and restart and it works. No clue but it is annoying.

Wow I can see how that can be annoying. Thanks for the input. hmmmm wonder if there's some sort of loose connection or possibly a faulty relay?

Mine did this. Starting and stopping the truck didnt help. Flipping the headlights on and off helped. Dealer says nothing wrong either. Only did it twice though

Mine has done it a couple times as well. Shutting the truck off and restarting fixed it dealer also could not find the problem

Tried the head light switching on & off along with restarting the truck.

Looked at fuses: 23 & 24. Both are still good.

Giggled the wiring behind the unit and pushed in the plugs, but no luck.

Still up for any suggestions. The dealer is the last resort.

Would anyone have or can direct me to a wiring diagram (pin out) of the 2 plugs going to the climate control unit?

I want to make sure there's power going to the plugs.

Thanks guys!

Just FYI guys, pulled the 2 plugs out of the climate control unit, checked them for power with a light tester (found two wires supplying power), & plugged them back into the unit.

Now it's working! Go figure....but happy it's ok. Thanks for the help everyone!

L250, I also have the same issue as you with the same year model truck. Can you please describe where that plug is that you finally found or provide a photo. Thanks
