Dual control acting up?


Recommended Posts

Looks like the dual control is acting up on my 2012. With the A/C running get cold air out the driver side vents, but hot air out the pass vents. I checked all the controls, dual is off, temp set to LOW, etc etc...but hot air coming out the passenger vents.

 

Any thoughts before heading to my mechanic?

 

Thanks,

could be lots of things, but my 2011 Limited started acting odd on just the drivers side. I would have to put the temperature all the way to high and then bring it back down for it to react. Took it to the dealer 2 weeks ago. Their diagnosis on my invoice says " HVAC Control Module reprogrammed with latest calibration per TSB 11-8-7"

 

Seems to have fixed mine. Not sure if will apply to 2012
