Universal Air SW11478C HVAC Blower Motor Resistor

Mercedes-Benz Blower Motor Resistor

Universal Air SW11478C is an HVAC blower motor resistor for select 1994-1995 Mercedes-Benz models. It is used to control blower motor speed in the cabin HVAC system and is listed for C220, C280, and C36 AMG applications.

Key Features

• Brand: Universal Air Blower Resistor line
• Part number: SW11478C
• HVAC blower motor resistor for cabin fan speed control
• Compatible with select Mercedes-Benz C220, C280, and C36 AMG applications
• Direct fitment coverage for 1994-1995 Mercedes-Benz C220 and C280, plus 1995 Mercedes-Benz C36 AMG

Application Details

Fits 1994-1995 Mercedes-Benz C220, N/A. Fits 1994-1995 Mercedes-Benz C280, N/A. Fits 1995 Mercedes-Benz C36 AMG, N/A. If your Mercedes-Benz C220, C280, or C36 AMG has inconsistent blower speeds or a fan that only works on certain settings, SW11478C is the correct HVAC resistor to verify against the original part.

Common Issues It May Address

• Blower motor works on only one speed
• HVAC fan speeds are intermittent
• Cabin air output is stuck on high or low
• Resistor failure causing loss of multiple fan settings
• Uneven or unreliable interior airflow control

Installation Notes

Confirm the original resistor connector, mounting style, and vehicle application before installation. Inspect the blower motor and related HVAC wiring for heat damage or corrosion, since those conditions can contribute to repeat resistor failure. Part number SW11478C should be matched to the vehicle’s original HVAC configuration for proper operation.

Quality Assurance

Universal Air SW11478C is cataloged as a blower resistor for the listed Mercedes-Benz applications and should be verified against the vehicle’s existing HVAC component before replacement.
