2009 Traverse Heat Selector Switch Not Working

Hi,

I have a 2009 Traverse LS with manual heat controls. The heat selector switch is stuck on vent. No matter what position I place the switch in, defrost, floor, floor + defrost, vent, etc, the air only blows out of the vents.

Can anyone give me some advice on where I can start looking to try and fix this?

Thank you.

Re: 2009 Traverse Heat Selector Switch Not Working

could be the head unit (where the selector is)...

or

with engine off--- radio off-- and quiet in the car---

listen carefully-- and move the selector to the different positions--- you should be able to hear the mode door move..
Or attempt to move.

Its possible one of the doors is stuck and not able to move.

There has been a few cases reported of a warped door that gets stuck-- or warped case.. which requires replacement.(I think for this the dash has to be taken apart)

I have a 2009 LT, and I had the door inside the dash replaced last week because of the exact same problem.

Re: 2009 Traverse Heat Selector Switch Not Working

I've moved the selector to the different positions and you can briefly hear it try to divert. I think the selector switch is fine.

I went ahead and partially disassembled the dash. Looks like most everything is located on the passenger side behind the glove box. Can anyone confirm that there only 3 actuator doors?

Also I'm looking for some logic on this. If the vent is the only one that works no matter the setting, does that mean that both the floor and the defroster door are stuck and can't open or does it mean that the vent one is stuck open and can't close? Is there a way to test them individually?

Thanks

@EasyTZ, Iím happy to read you were able to get this resolved under warranty. Please, keep in mind if the dealership used genuine GM parts there should be a 12 month or 12,000 mile warranty on the parts and labor. This warranty will expire either on time or mileage, whichever happens first.

Re: 2009 Traverse Heat Selector Switch Not Working

Did you check to see if the heater core valve actuator is working?

We just had one go out at 58000 miles on 2009 Traverse.
It would get stuck in the hot position with the valve open that controls hot engine coolant entering the front air box (air handler box like in a home AC). When I pulled the passenger side glove box and lower panel I could see the motor trying to work and could help it out by pushing directly on the valve to get it where it needed to be.

Thus, if the "Hot <-> Cold" selector dial was turned to "Cold", the valve would likely still be part way open and the hot coolant entering the heat exchanger in the air box would be fighting any cooling efforts from the evaporator. Result: AC would appear poorly functioning.

Anyone know if there are separate valves for both front and rear air boxes? This might cause some discrepancy between front and rear cooling capability as well.

Bought from Josh Lee
Service Manager: Kevin
Parts: Charlie
All been real professional in my experience.

Quoted 78.78 + tax and they keep several in stock to the advantage of customers that might have this issue as it is not uncommon. This is money on the shelf so recognition goes to GM and the dealer for having these available. Thanks.

Re: 2009 Traverse Heat Selector Switch Not Working

I have a 2009 LT with the same problem. Heat blows out the vent only. The dealer inspected this and says the actuator doors are stuck for some reason unknown to them. They claim the cost to repair would be very expensive and I think they mentioned $2,000+. I was very surprised and decided not to do anything, but with the cold weather of winter this is really not a great way to enjoy driving with cold feet and foggy windshield. Does anyone have a suggestion for me? I'm likely not going to attempt to fix this myself. Should I take it to a different dealership? Does anyone have an idea what this repair should cost?

Re: 2009 Traverse Heat Selector Switch Not Working

I have read thread on warped casings-- where the blend doors cant move/get stuck.
They did have to tear apart the dash to fix.
is this your issue? possibly.
or an actuator has died....

look at this thread so you know what actuators are..

http://www.traverseforum.com/index.php?topic=3042.0


but What I would personnaly do-- if I didnt want to pay $2000.

Is Id find the actuator that controls the door to provide heat to you area. Id check to see that the actuators actually work.
Id try to get in there and either by replacing the actuator-- or somehow moving the blend door-- Id move it- and leave the plug to the actuator unplugged... so it wont move....
