Common HVAC Problems It Can Solve

• Stuck recirculation door operation
• Incorrect cabin temperature blending
• HVAC airflow that does not respond to control changes
• Clicking or inconsistent actuator movement behind the dash
• Loss of proper heater or A/C air distribution

Installation Notes

Verify the vehicle’s HVAC configuration, including dual-zone temperature control, ATC, VIN breakpoints, and Valeo system notes before ordering. Confirm the actuator position and connector style match the original unit; Dorman 604-837 uses a rotary activation design with a 2-pin male terminal layout. Access is typically behind the dash or HVAC housing, so compare the original actuator and door arm arrangement before installation.

Quality Assurance

Dorman engineers this HVAC heater blend door actuator to match the quality and performance of the original part on the listed applications. The plastic housing, OE-style terminal layout, and included arms support a direct-replacement repair for select Audi and Volkswagen HVAC systems.
