Traverse heat/defrost issues #4559940

'09 Traverse; have been having this problem intermittently. If I have the temp toward hot, it doesn't want to go back to cold, and vise versa. I have been getting it to change just by messing around with controls. Put blower on full blast, back and forth to hot/cold, etc. But this really should be fixed. From what I gather, it's a blend door actuator.

Now I'm having another issue: I can get heat out of the bottom vents, but not out the defrost vents. I believe this function is controlled by a different actuator.

Anyone else have this type of experience with one of these vehicles. Any tips on where to find these actuators? Going to try to look at it tonight.

Thanks

You may need a new climate control panel and the definitely a new blend door actuator

I did the HVAC resent and as of now everything is working properly. I pulled glove box, and saw both temp, and vent function actuators moving when they should be moving.

So hopefully they stay working...
