2006 DODGE RAM SRT-10 instrument panel

The blend door actuators are diagnosed using a scan tool (Refer to 24 - HEATING & AIR CONDITIONING - DIAG-
NOSIS AND TESTING and to 24 - HVAC Electrical Diagnostics for more information).
The blend door actuators cannot be adjusted or repaired and, if faulty or damaged, they must be replaced.
REMOVAL
WARNING: On vehicles equipped with airbags, disable the airbag system before attempting any steering
wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the
battery negative (ground) cable, then wait two minutes for the airbag system capacitor to discharge before
performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to
take the proper precautions could result in accidental airbag deploymentand possible personal injury or
death.
NOTE: The single zone heating-A/C system is equipped with a single blend door actuator. The dual zone
system has two blend door actuators, one for the driver side blend-air doorand one for the passenger side
blend-air door.

The mode door actuators cannot be adjusted or repaired and, if faulty or damaged, they must be replaced.
REMOVAL
WARNING: On vehicles equipped with airbags, disable the airbag system before attempting any steering
wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the
battery negative (ground) cable, then wait two minutes for the airbag system capacitor to discharge before
performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to
take the proper precautions could result in an accidental airbag deployment and possible personal injury or
death.
NOTE: The heating-A/C system is equipped with two mode door actuators, onefor the panel/floor-air door
and one for the defrost-air door.
PANEL/FLOOR DOOR ACTUATOR

door actuator (2) to the back of the HVAC housing
(3).
4. Remove the panel/floor door actuator from the
HVAC housing and disconnect the HVAC wire har-
ness connector (4) from the actuator.
5. Remove the panel/floor door actuator from the
vehicle.
