Vehicle listed above is a Limited model. While driving on a dirt road my climate control lost power. The control panel lights went out and the blower stopped. I looked at the fuses but I’m unsure which fuse(s) is for the climate control.

I did remove the control panel from the dash to inspect the plugs and look for a shorted wire. Everything looks good. Just unsure how to proceed. I don’t like throwing parts at a problem until I know what the root cause is.

Any information will be greatly appreciated!

We need to start by checking the fuse # 1, 10 and 21 in the under-hood fuse panel, and fuse # 7, 20 and 21 in the interior fuse panel. here is a guide to help and the fuse locations in the diagrams below. Also, I have included the A/C and HVAC wiring diagrams so you can see how the system works.

Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.
