AC cold on passenger side, warmer on driver side. Where is the driver side blend door actuator located? A picture would help and how to get to it.

The driver side blend door actuator is on the left side of the HVAC plenum above the gas pedal; you will need to remove the knee bolster and the instrument cluster. There will be two of them close together, you want the one that hangs down further than the other. Check out the images (below). Let us know if you need anything else.
