2006 Chrysler 300 blows cold air from the drivers side and hot air from the passenger side whats up

Check the fuses, some dodges have power supplied to the body control module,that run the hvac doors, also some body control modules need programmed if the battery dies,or is removed. Programming will be indicated by flashing lights on controls a/c button and recurculation. Small light usually orange or yellow, when key is on w fan running the controls switch simultaneously on their own indicates blown fuse,this car is equipped w dual fuse boxes,under hood and dash

I wish I knew the answer, mine does the same thing. Those o6 300 must have been built by a bunch of drunks.

Chrysler are know to break blend air doors and that what causes your problem. Had this happen on my Chrysler product, very expensive to fix as the whole dash has to come out to get to the heater box. Nasty job.
