My 2008 Chevy Uplander has no REAR heat but the rear ac works fine. The front also as great heat and does NOT have the usual "no heat at idle" problem. Does the rear ac/heat system use an actuator for a blend door like the front does? If yes were is it located? If no what controls the blend on the rear? Rear fan is working.

Yes, it has an electric blend door actuator that is controlled by the Control head in the front.

The Auxiliary unit is in the left rear cargo area and the blend door actuator is #6 in the picture.
