  Q: How to replace the blend door actuator on Dodge Ram 3500 Van?

  A:

  For the replacement, start by disabling air bags by removing and separating the battery negative cable and wait for two minutes to ensure the air bag batting capacitor is not induced. Remove the glove box from the instrument panel and remove the wire harness connector from the blend-air door motor after reaching into the opening available in the glove box. Remove the link after unlatching the retainer at the top of the blend-air door motor lever. After that, use aflathead or Phillips screwdriver to remove the three screws fastening the blend-air door motor to the top of the distribution duct, then take off the motor. Pick your spot on the distribution duct and then put in the new blend-air door motor with the help of three screws tightened to 2.2 Nm (20 in. lbs.). Set the metal retainer under the air door lever link, between the bumps and snap it into place. Once again connect the wire harness for the blend-air door motor, slide the glove box into place and ensure the negative battery cable is secure.

  Q: How can the rear Blend Door Actuator be removed and installed equipped with the optional rear heater-A/C unit on Dodge Ram 3500 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.
