APPLICATIONS

The PACCAR T6892003 HVAC Door Actuator is associated with selected Kenworth and Peterbilt commercial truck HVAC systems.

Potential vehicle applications include:

• Kenworth T680

• Kenworth T880

• Peterbilt 567

• Peterbilt 579

• Peterbilt 589

• Other Kenworth and Peterbilt models equipped with compatible HVAC actuator configurations

Compatibility depends on the truck model, model year, HVAC system design, original actuator part number, and electrical connector configuration.

Important: This actuator may serve different HVAC door functions depending on its installation location. Verify the original part number and actuator configuration before purchasing.

FUNCTION

The PACCAR T6892003 HVAC Door Actuator uses an electric motor to position an internal HVAC air door in response to climate control commands.

Depending on the vehicle's HVAC configuration, the actuator may control the blend of heated and cooled air, direct airflow between ventilation outlets, or switch between outside air and cabin recirculation.

A worn, damaged, or failing HVAC door actuator may cause symptoms such as:

• Incorrect or inconsistent cabin temperature

• Clicking or knocking noises behind the dashboard

• Hot or cold air blowing regardless of selected settings

• Airflow failing to switch between ventilation modes

• Recirculation mode not operating correctly

• HVAC door movement becoming intermittent or completely inoperative

WHY REPLACE AN HVAC TEMPERATURE DOOR ACTUATOR?

A malfunctioning HVAC actuator can prevent the climate control system from properly adjusting air temperature, airflow direction, or recirculation settings.

Replacing a defective actuator with the correct Genuine OEM PACCAR T6892003 component helps restore intended HVAC door movement and climate control functionality.

Proper HVAC operation supports driver comfort, cabin ventilation, and windshield defogging performance during changing weather conditions.
