2002 chevy trailblazer_ls
I went to gmpartsdirect searched for the part number you listed. I have a 2002 TB LS 2.4L but it states its the wrong part. The diagram for the 2008 shows It as the middle actuator under driver dash. So it's the same part I need to replace. But It only lists it as a actuator GM no specific details. So I searched again but there's no same part coming up for my 2002 model. I then went to auto zone just to see what it gives me. They lists it as a Heat AC blend actuator. There's three for my base model for the main vents. One is this "Main Air distribution mode Actuator Only." This ones $138 so I assume its the wrong one. It has two others in the $40-50 range one is listed as the "Main. Air distribution mode. Cam and Actuator Assembly." The second is listed for the "Main. Air distribution mode. Actuator Only." The actuator only looks like the part you have pictured but doesn't show clearly the white gear coming out the side. I want to order the correct part online to get the best price but not to confident I can find the right one. I'm a novice a repairs so this will be a more advanced repair. So any help is greatly appreciated.
