  Q: How can the rear Blend Door Actuator be removed and installed equipped with the optional rear heater-A/C unit on Dodge Ram 1500 Van?

  A:

  Only in cars equipped with the optional rear heater-A/C, the control motor can be disconnected from the rear heater-A/C without taking out the whole unit. Disconnect and isolate the battery negative cable as the first step, then take off the cover from the rear heater-A/C unit and remove the vertical and horizontal ducts. Disconnect the wire harness connector from the rear mode control motor that is found on the outside edge of the upper housing just in front of the heater-A/C unit. Remove the three screws holding the rear mode motor and slide it away from the upper housing until you can remove it without breaking the connection the motor has with the water valve control adaptor. Anchor the rear mode control motor hub over the water valve control cable adaptor, making sure the flats in the motor hub are in the same place as those on the adaptor. Apply three screws to the motor's mounting bosses in the upper housing and tighten them to 2.2 Nm (20 in. lbs.). First, attach the wire harness connector back to the motor, then place the horizontal and vertical ducts into position and finally, cover the rear unit with the heater-A/C door. The final step is to attach the negative battery cable once more.

  Q: How to replace the blend door actuator on Dodge Ram 1500 Van?

  A:

  Before replacing the blend door actuator, turn off the air bag system by removing the car battery's negative cable and wait two minutes to allow the air bag capacitor to run down. First, take out the pedestal gauge panel and use the hole left by the glove box to disconnect the motor's wire harness. Turn the blend-air door motor lever to disengage the lock, then pull on the link to take it out. Once that's done, unfasten the three screws from the top of the motor to the distribution duct and remove the motor. Place the new blend-air door motor into the distribution duct, use the three screws to attach it and tighten them to 2.2 Nm (20 in. lbs.). Place the link to the retainer on top of the blend-air door lever so it stays there correctly, then close the link. Place the blend-air door wire harness connector, secure the glove box back in place and twist on the negative lead of the battery.
