Detailed Description
This Universal Air blower resistor is used in HVAC systems to regulate blower motor speed through the resistor circuit. It is cataloged for select Ford Focus, Mercury Cougar, and Ford Thunderbird models, making it a fitment-specific replacement for vehicles that use a standard blower resistor rather than Automatic Temperature Control. If you are searching for a Ford Focus blower resistor SW11573C or a Mercury Cougar HVAC blower motor resistor, verify the vehicle year and climate control setup before ordering.
This part cross-references no additional part numbers in the provided data.
What It Helps Fix
- Blower motor works on only one speed
- Intermittent cabin fan operation
- Loss of lower fan speeds
- HVAC fan speed control problems
- Resistor failure in manual climate control systems
Installation Notes and Tips
Confirm the vehicle year, make, model, and HVAC control type before installation. This part is not listed for Automatic Temperature Control applications on the affected Ford Focus, Mercury Cougar, and Ford Thunderbird vehicles. Compare the original connector and mounting location to the existing resistor before replacement.
