AC Dial Stuck
This is wierd...has any one experienced turning the ac dial (on the driver side for me) only to find that when you turn it to go warmer the red light stays lit on the temp that is was already set to?
This happened several times today. Sometimes when I would turn it clockwise of off 72 degrees to the right the red light would stay put and not move (temp would not adjust either) or it would jump to the left
and get colder, even though I was turning it to go warmer. Strange.

Most likely a bad or defective HVAC module (dash unit) Not a big deal to change out and it should be under warranty.
