2008 chrysler aspen heater contols does not switch modes. It is stuck on vent setting, won't switch to defrost, floor, etc.
I've had this problem almost since I bought my Aspen hemi limited at 114k. I tried fuses, key turns, battery resets..ONE THING almost always (95% of the time) works...
start at HIGH in climate control, press both zones at same time to go to LOW. Once you hear it engage the cold side, press both zones at same time but this way go back up to HIGH. The system will then engage heat, and you should be nice and toasty. I swear this works. 221k on my hemi limited. Heat is cranking with the climate control problem, and vice versa to engage ac/cold side. Hope this finally helps everyone I know what a pain freezing in your truck at 5 am is. Namaste!
