Condition
Some customers may comment on a lack of sufficient air flow from the instrument panel vents when the vent mode is selected and the temperature
control is at full heat. Others may comment that the volume of hot air flow from the instrument panel vents may seem to be less than the air flow from the
floor ducts.
Correction
Disable the temperature sub-damper door, located inside the air conditioning module, using the following procedure:
1.
Turn the ignition key to the "ON" position and move the HVAC (heating, ventilation and air conditioning) temperature control to the full cold
position.
2.
Turn the ignition key to the "OFF" position.
3.
Remove the instrument panel closeout/insulator panel.
4.
Remove the instrument panel compartment.
Important:
The mode door actuator described below may not be found on all vehicles. The actuator removal and replacement instructions are not
necessary if this actuator is not present.
5.
Locate the mode door actuator on the passenger side of the HVAC module. Disconnect the actuator electrical connector. Remove the two actuator
retaining screws and the mode door actuator.
