New too the forum. Hello everyone! I am having a problem with my rear air/heat. It switches from floor to ceiling and back fine. The temp is the problem. When I got it last fall it was stuck on cold air. I messed with it and put on a new control module. I did the reset and it went to heat. Now I can't get it to cold. I swapped the actuators and they both seem to work fine changing floor to ceiling. I even tried moving to cold using a wrench to turn it. Still no luck. The air gets cooler but still not cold enough for air. At this point I'm wondering if I got a bad control module, if something is wrong inside the door, or does the temp door take more power and neither actuators has enough power. If anyone has a n idea I'm all ears. Thanks in advance. Mike

 

Perhaps the blend door is broken inside.
