A-NAFTULY Blower Motor Resistor Kit with Harness for 2003–2006 Chevy/GMC (89019088) — Restores Multi-Speed HVAC Control

A-NAFTULY 89019088 blower motor resistor kit with harness restores full HVAC fan-speed control for 2003–2006 Chevrolet, GMC and select Cadillac models.

If your vehicle’s heater or air conditioner only works on one fan speed, or stops blowing air entirely, the blower motor resistor is a common culprit. This direct-fit replacement kit is designed for manual A/C control vehicles without rear center-console vents and with a 4-hole mounting flange. It matches multiple OE numbers and fits many Chevy and GMC trucks and SUVs from 2003–2006, offering a straightforward swap to bring back reliable fan operation.

How does this blower motor resistor restore HVAC performance?

The resistor controls the electrical path to the blower motor, changing the fan’s speed settings. When the resistor fails, the fan can get stuck on one speed or stop; swapping in this new module restores proper electrical resistance and returns full speed range and airflow consistency.

• Re-establishes multi-speed fan control for heating and cooling
• Solves no-blow or single-speed blower symptoms
• OEM-style resistive elements for reliable performance

Is installation difficult and what tools are required?

Installation is typically straightforward and requires basic hand tools. The resistor is mounted on the lower passenger side of the HVAC housing; remove the retaining screws, unplug the electrical connector, swap the old module for the new kit and reattach the screws. No specialty tools or advanced skills are necessary.

• Located on lower passenger-side of HVAC housing for easy access
• Simple removal: unscrew, unplug, replace, and secure
• Includes replacement harness to ensure a proper electrical connection
