Hi Sherilyn, This is for 2003-2009 GMC Envoy. To check the fitment please use our Vehicle Selector — which can be found towards the top of the homepage as well as all categories, search results, and product pages — can help verify if a part will fit your specific application. To enter your application, simply select your vehicle’s year, make, model, sub-model, and engine type and click “Go.” Once your application is selected, you’ll see a “Guaranteed to Fit” badge if the part will fit, and we recommend that you also double-check Your Vehicle Fit Details as well as the Vehicle Fitment Information table on the product page.

The plastic piece is the actual temp adjustment - it's what moves when you slide the temp gauge in the center console - definitely need it! If the piece is still attached inside your vehicle, then you can slide this piece on to it, however, you'll need to know where the actuator is set to and match the inside temp gauge before installing - I found I needed the inside set to max heat for this to slide on and work correctly

There is two of them under the driver side steering wheel one that comes with the white piece and one without. I'm guessing you took apart the one with out the white piece. But the other should fit perfectly and you can't take off the white part because you'll break it. I believe the one with the white thing is to control the vents for the a/c and the one with out is to control the speed on the a/c.

There are 3 different blender doors. Not interchangeable. Get the EXACT one that you already have - same holes, etc.

My 2009 called for this, it's wrong for the passenger side with manual control

Hi Adam, thank you for reaching out. We highly suggest that a certified mechanic diagnose your vehicle to pinpoint the part that needs replacement. Have a nice day.

This part does help if the problem is Switching between top vents and floor.

I have a 2006 envoy. I ended up having to replace all 3.

Hi Earl, thank you for reaching out. No, it should not. Kindly call our parts team at 1-866-529-0412 and provide the complete vehicle information. We'll be more than glad to help you look for the correct part. Have a nice day.

My 06 Envoy needed this gear. So if your old one doesn't have it I would think you can remove it. I reached under with my phone and took a picture of the old one. It's not easy to get to. Butch

My advice would be to take it to a repair shop that can run the test on the HVAC system with a high-quality scanner so they can run through each scanner in that system. You wouldn't have to let them fix it, but you would know which actuator it is that is failing.

This looks like the one I purchased. Mine fit in the upper center of my 06 Envoy. Access to it was from the Driver's side under the dash.
