Any JL experts out there.

I have a 2018 JL and the climate control system quit working. It only blows hot air out of the defrost vents. What should be looking for?

A jeep full of hot air?

Might be the driver.

Most likely a vacuum issue, when there is a loss of vacuum, the system will default to the windshield as a safety measure to keep the glass clear.

I pulled the fuse, let it sit overnight and now it seems to be working.
