3 times now my climate control has failed to work when I go out to the truck in the morning. All 3 times it has been below freezing. I am unable to use any of the functions. No changing the temp, turning on the defrost, etc. The air comes on, but you just can't adjust anything. After the truck warms up it begins to function. Anyone else had this issue?

 

Yep, it's annoying as hell. I've been tempted to take it in but I know unless it does it while I'm there, I'm screwed. Also, when I turn on my defrost, I can't turn it off. I have to wait a few minutes and hit every damn button on the climate control panel until I hit the lucky button that will turn it off.

 

If I'm not mistaken, the system is designed to work on one setting at full heat until the interior reaches a certain temp. Once it does then it'll allow you to adjust it to your liking. Might want to consult the owners manual on that one though.
