At least that's what I think they're called anyway, I have two AC units on the suburban, and one nobody seems to be able to find the leak and number two, I need to replace a blender, I am pretty sure I know which one it is, but what I'd like to know is how many blenders are in the suburban when you have two AC units.
Also, the AC unit in the back doesn't seem to blow for some reason, it doesn't matter if we use the controls in the front or in the rear. I have not tried to see if the heat work or not, I suppose I should.

Your assistance is greatly appreciated.

Hello,

The blend door actuators do control the vents that the air goes to. I have included in the diagrams down below a complete description of your vehicle's Heating Ventilation and Air Conditioning system (HVAC) system. I have also included a link below for you to go to on the blend door actuators.
