Blend door actuator identification is still confusing to me after reading and watching your video. I’m not sure which one to replace. Can you help? My vehicle is a 2004 Avalanche and has dual climate controls. AC is fine on drivers side, AC blows hot on passenger side.

No problem we are here to help.

Here is a guide that will help you see what's going on. The blend door actuator you want is on the bottom like the one in the video.

Also you might want to try to recalibrate the system by removing the HVAC fuse for 5 minutes.

Please let us know what happens.

Cheers, Ken
