This video covers the process of repairing, and replacing, the electronic blend door actuator on a 1998 Chevy Blazer. The process covered in this video will be the same on many other Oldsmobile, Chevy, GMC, and Pontiac vehicles. When the blend door actuator fails you may notice constant heat air, constant cold air or hot and cold air may toggle back and forth if the computer is trying to learn where the blend door is. This video also provides a close up view of the blend door actuator in correct synchronization. The blend door replacement and repair process is the same whether working on a manual heat control or the automatic temperature control (computerized climate control) in General Motors vehicles. I used JB Weld to repair the cracked blend door actuator gear in this video.How to set the timing on a GMC blend door actuator.
