Heater control ////hot or cold?????

Hey Guys, I have a 2009 Traverse LTZ. Just discovered that the heater control seems to be hot or cold. If I have set to 60 it's gets ice cold, if i want 68 lets say it goes to very hot although it's showing 68. Doesn't seem to be adjustable in-between 60-90? Any ideas to avoid going to the dealer Thanks

Re: Heater control ////hot or cold?????

sounds like one of the cabin sensors is not reading the correct temp for its area.

Does the outside temp read correctly?

Yes outside temp is correct and changes accordingly. The inside is either 60 or 90 no matter how you adjust it in-between the two. If on 60 it is cold and 60. But go to 61 0r 70 and it is coming out at 90.

I would also look at the blend door to see if it is binding or sticking or an actuator not responding correctly. At 60 it is all the way closed and allowing only the A/C cold air to enter. If you set it to 68 it may open all the way and allow only the heat to enter with no cooling air added.

May also consider the head unit being defective, although I haven't read about too many problems with them. More posts about the blend door and actuators. Any difference in heat/cooling on the driver's side versus the passenger side? I am guessing you have the auto temp controls with separate settings for each side?

If there is a difference between the two sides that would more than likely suggest an actuator. There are two on each side for a total of four.

If each side is the same hot/cold, I would look closer at the head unit or the blend door.

I actually didn't check the pass side independently I will tomorrow. But yes it is just hot or cold regardless of the mid adjustment. Thanks for the relies so far guys! I'll check back after I check pass side.

There are some IC chips behind this meter who controls temp and forward instructions and i think there is some problem with that IC chips so if you can repair itself then check you IC's otherwise you need to go to the dealer.

Hi again CGIM5804,

My internal resources want to verify that it is the front air actuator that you are seeking the part number for. Thanks!
