Recently I have been having some issues with my climate control. Every once in a while, after the car has been running for a while, the passenger side vents will start blowing out hot air. The driver's side always stays very cool, and I always have the controls set at automatic w/ the temp the same on both sides. It seems to be happening more and more often. Sometimes simply turning the system off then back on will reset the problem, but other times, it takes turning the car completely off. If anyone has some advice or experience w/ this problem, let me know. Thanks.
