This one is a real head scratcher. The other day it finally cooled down to the point where I'd need to use the heat in my Intrigue for the first time since bought it back in July. I have the auto dual-zone climate control system, so I set it up and waited for the warm air to come. It never did. After fidgeting around at every light and switching the vents it would come out of I finally realized the hot air was coming out fine in all modes on the passenger side, but the driver s side is geting the frigid outside air. There's no weird or louder noises to immediately indicate any sort of problems, anyone here have any ideas?
