I have an 07 Pacifica FWD 4.0L Is there a diagram for the location of the blend door actuator, the auxiliary one. I’ve read it could possibly be behind the dash. I just don’t want to tear everything out and it not be there.

The issue I’m having is I’m not getting air out of any of the vents in the front of the vehicle. I’ve replaced main blend door, blower motor, and the blower motor resistor. I’ve also checked all the fuses and relays. I’ve also tried recalibrating the blend doors by holding power and recirculating air buttons. It continues to flash meaning there’s a problem somewhere.

 

The "blend door" controls the mixture of warm and cool air to control the temperature of the air coming in to the car. The "mode door" controls the direction of air to flow to the dash outlets, the floor outlets or the defroster.
