Description

This air door actuator directly replaces the original actuator on specific vehicle years, makes, models, configurations and positions to restore proper HVAC operation. Please note that many vehicles have several different air door actuators, which are designed for specific positions and functions in the vehicle. To ensure you have what you need, carefully review the application notes for this part to verify it matches the position and function of the actuator you need to replace.

  • Fits a 2002 Blazer with manual temp control
Ordered for a 2002 Chevy Blazer as the original had stopped working. Replaced with this actuator. This fits perfectly and works as it should. Good product for a very reasonable price compared to OEM.

  • Blend Door Fixed
Install is easy as long as you have the right tools / small enough hands. Set the blend door by hand to align with this, reset the RDO fuse, and voila, you’ve got air again. Part is easier to rebuild if needed compared to OEM (latches together but still strong, dense plastic). No noise during operation like my old one. This was 20$ cheaper than the auto stores around me. Overall, great part and deal. ... show more

  • Does not work with 2004 Escalade
Even though this actuator looks like it is a direct replacement, the connector pins do not match up with the ones that came off of my 2004 Escalade. I checked Dorman's actual website prior to purchasing and they stated it would work. I was attempting to replace the rear temperature actuator. No luck. There were two in the back. I replaced the known good (working) one with this one and could not get it to power up or do anything. Returning to Amazon and will have to go for a genuine replacement part. ... show more
