This is your temperature actuator. When its on fully cold as you can see in this picture it should be all the way to one side, and the other when hot.
Sometimes over time this will not be the case. There is apparently a service notice about this out there, however GM has not had a recall on this.This project, if I had to do it again, probably would only take 30 minutes to complete. I pulled my replacement actuator from a junkyard for 5 bucks. I like to use junkyard parts not only for the price but I also get to see how to remove the part on another vehicle without the risk of ruining my own!
Flashlight (preferably one that is small as I found it easiest to stick it in my mouth to use two hands at once
To start with, remove the drivers side end panel. This is held on with clips and should just pull off.
Then remove the trim underneath. This is also just held on with clips. I believe that there might be a bolt that connects this to the other side, however I think I broke that piece off another time.
Finally remove the trim above the pedals. This is held on with those dumb black plastic Christmas trees. Pull downward at the trees to remove. Make sure to disconnect the light bulb as it will hang and burn your forehead!
I found the best way to see/get at the actuator is to move your seat all the way back and tilt your wheel all the way up. Then put your legs over the back of your front seat, and have your shoulders down on the floorboards looking up. You will look ridiculous and might get a rush to your head, but this is the easiest way to work as you can use both hands and be able to see. When you look up and to the passenger (if you"re laying like I was it will be your left) side you should see this
This is your actuator. My driver is pointing at the first screw. I"ll show you this screw better in a later picture. First thing you"ll want to do is remove the electrical connector. It was red on both mine and the junker so I can only assume yours will be too. Ignore my driver in this picture I was attempting to point at the 2nd screw. The connector is to the upper right of the white sticker in this picture.

After removing the connector remove the first screw/bolt, seen here. Ignore the tiny phillips screws, they hold the actuator together and do not need to be removed. This screw is located at the bottom left of the white sticker in this picture.
