Four Seasons 20956 front A/C power module for the 2000-2005 Pontiac Bonneville and other vehicles controls the speed of the HVAC blower motor. Also known as an HVAC blower motor resistor, it limits current to the motor so the fan can run at different speeds.
- Finned heat sinks for cooling
- Ground wire to prevent RFI
- Rectangular female connector with 3 and 3 blade terminals
- Vehicle-specific calibration and vehicle-specific applications
Quick facts
- Part: Four Seasons 20956 A/C power module
- Fits: 2000-2005 Pontiac Bonneville and other vehicles
- Position: Front
- Condition: New
Blower speeds that drop out, or a fan that does not run at all, can mean the resistor has worn out. A failing blower motor or a damaged wiring connector can be behind those signs too, so find the cause before replacing it.
Fits
This front A/C power module also fits the 2000-2005 Buick LeSabre and the 1998-2005 Cadillac DeVille. For any other year or model, look in the "Vehicles it fits" section.
