HVAC Blower Motor Resistor for Volkswagen Applications
Restore proper blower fan control with this Standard Ignition HVAC blower motor resistor, part number RU-426. It is a 12-volt resistor assembly with a 4-blade male terminal layout, female connector, and screw attachment method for select Volkswagen HVAC systems.
Compatible With 1993-2005 Volkswagen Golf, Jetta, Cabrio, and Passat applications, including 3-5 speed blower control setups where listed fitment applies.
Key Features
- Standard Ignition RU-426 HVAC blower motor resistor
- 12-volt electrical design
- 3-5 speed blower control coverage
- Female connector with 1 connector cavity
- 4 male blade terminals
- Screw-mounted installation style
- No wiring harness, mounting bracket, or hardware included
Detailed Description
The RU-426 is an HVAC blower motor resistor used to regulate blower fan speeds in select Volkswagen heating and air conditioning systems. It is built with a female connector, four male blade terminals, and a screw-in attachment method, making it a direct service part for vehicles that use a resistor-based blower speed circuit rather than automatic temperature control. This part cross-references Four Seasons 20352 for the same application.
Use RU-426 when servicing Volkswagen Passat, Jetta, Golf, or Cabrio blower speed circuits that rely on a 3-5 speed resistor design. The part number RU-426 is also referenced in interchange listings for related OE-style applications, including Volkswagen HVAC systems that use the same connector and terminal configuration.
What It Helps Fix
- Blower motor works only on certain fan speeds
- HVAC fan stays on one speed
- Cabin airflow is weak because lower speeds do not operate
- Intermittent blower speed operation
- No blower response from the resistor-controlled speed circuit
Installation Notes and Tips
Install RU-426 only on vehicles listed in the fitment data. Confirm the vehicle does not use automatic temperature control on 1998-2005 Volkswagen Passat applications, since those vehicles are excluded. Match the connector style, terminal count, and screw-mount design before installation. Inspect the blower motor connector and related wiring for heat damage or corrosion, since a failed resistor is often accompanied by damaged terminals.
