Key Features

• Rotary switch activation type for HVAC mode door control
• 5-pin male terminal design for the specified vehicle applications
• Plastic housing construction
• Direct replacement for the original blend door actuator on listed Volkswagen and Audi models
• Designed for vehicles with Automatic Temperature Control (ATC) or electronic temperature control, depending on application
• Part number 604-836 for easy identification and ordering

Detailed Description

This HVAC blend door actuator controls the movement of the air door inside the heating and air conditioning system, directing airflow to the proper vents. Dorman 604-836 is engineered to match the original actuator’s quality and performance on select Volkswagen Jetta, Golf, and Clasico models, as well as Audi TT, TT Quattro, A3, and A3 Quattro vehicles. The fitment coverage includes 2003-2015 model years across the listed applications, with notes for ATC, electronic temperature control, build location, and VIN breakpoints.

Use Dorman 604-836 when servicing a mode door actuator on a Volkswagen Jetta, Golf, or Audi TT platform vehicle where the HVAC system is not directing air correctly. The part number 604-836 is also a useful reference when matching the correct replacement actuator for the specified factory control setup.

What It Helps Fix

• Airflow stuck at one vent position
• HVAC mode changes that do not respond correctly
• Inconsistent cabin air distribution
• Loss of proper vent selection in ATC-equipped systems
• Faulty actuator movement caused by worn internal components

Installation Notes and Tips

Verify the vehicle’s year, make, model, temperature control type, build details, and VIN breakpoint before ordering. This actuator uses a rotary activation design with a 5-pin male terminal layout, so connector style and application notes should be matched carefully during replacement. Confirm the original part number and HVAC configuration on the vehicle before installation.

Quality Assurance

Dorman manufactures this actuator as a precision replacement for the original blend door actuator used in the listed applications. The design focus is on restoring factory-style HVAC operation for the specified Volkswagen and Audi vehicles.
