Car came back from a shop to change the windshield. I was driving in the dark and noticed that the climate control lights weren’t working. The module works perfectly fine, I have A/C, heat, can change temperature, but none of the lights on that module works.

Headlights are on.
Max brightness.
Center console lights and dash lights work.

Thanks in advance.

There is a ground wire (g10) on the left side of the dash that must have been left off or is not working. If these are the only lights not working, if more illumination lights are not working, I would check the panel fuse 7.5 amp in the fuse panel in the left side of the passenger's compartment. This guide will help you I have included the fuse location well:

Check out the images (below). Please let us know what happens.

Look around under the left side of the dash with a flashlight, it should be obvious. How was the fuse? You can call the shop that did the windshield to see if they remember disconnecting it.
