How to Replace a Blend Door Actuator on 2002 Dodge Ram 2500?

Before changing the blend door actuator, turn on the ignition, place the temperature control knob at mid-way and then turn the ignition off. Unplug the black cable from the battery first and afterward take out the vehicle's instrument panel and HVAC compartment. Remove one wire harness connector from the blend door actuator and then take out the two screws that hold the actuator to the blower housing. Take off the actuator from the shaft of the blend door; if its black plastic coupler connects it, check it for damage and reinstall it if it's okay. Make certain you can move the blend door freely in both its directions before you install the new actuator. After placing the actuator on the blend door shaft, rotate it to where the mounting bosses on the HVAC housing line up and install and tighten the actuator screws to 2.2 Nm (20 in. lbs.). Connect the wire harness to the blend door actuator, put back the HVAC housing and instrument panel and make sure the Temperature Control Knob is at the mid-point (12 o'clock) until the actuator is properly powered. Then, connect the battery negative cable once again.
