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.
