I have a 2000 venture van. What is the name of the motor the controls the blower air to the different ducts? The one in the van does not move. Help

 

Got my own answer. Its not a motor, its vacuum controled with a diaphram actuator. I found no vacuum at the switch on the dash. I found 3 holes in the line under the solvent bottle. I ran a new hose, and all in well with the world now.

 

I have a 2004 and it has both vacume actuator and a door actuator Wich is electric for heat or hvac door. Is it switching vents or not switching temp.
