I have a 2004 Ford F150 Lariat V8 that the climate control unit just completely went out, no power, nothing. I checked fuse #13 (10A mini fuse for Climate Control Module Power) and it seems to be okay, fuse tester lighter is green. I really don't want to spend Thanksgivings eating money on a new part unit or expensive repairs. Any ideas on what this could be? It was cold this morning!

 

Check the power wire on the wiring harness in the back of the controller.

If it is good then try this link. It has helped many people and save many $$$$
