MNJWS Blower Motor Resistor for 2003–2007 GM Trucks & SUVs — Direct-Fit, Multi-Speed Restore

MNJWS AC Blower Motor Resistor is a direct-fit blower control module that restores multi-speed fan control for selected 2003–2007 GM trucks and SUVs.

If the heater or air-conditioning fan in your Chevy, GMC, Buick, or Cadillac only works on one speed or not at all, a failing blower resistor/control module is a common cause.
