A-NAFTULY Blower Motor Resistor Kit with Harness for 2003–2006 Chevrolet & GMC — Direct-Fit, Restores Multi-Speed HVAC

If your vehicle's heating or air-conditioning fan is stuck on one speed or not running at all, this direct-fit blower motor resistor kit from A-NAFTULY replaces the worn module and harness to recover proper fan speed selection. Designed for manual AC controls without rear console vents, the kit matches OE fitment and includes an 18‑month warranty plus 24/7 support.

How will this resistor kit fix my fan speed problems?

The blower motor resistor regulates current to the HVAC blower so that different switch positions produce different fan speeds. A failed resistor often causes the blower to work only on high, remain off, or operate unpredictably. Swapping the old resistor and harness for a new unit typically restores full speed range and consistent operation.

• Restores variable fan speeds controlled by the dash switch.
• Addresses symptoms like blower stuck on one speed or no airflow.
• Includes harness to ensure reliable electrical connections.

Which vehicles and part numbers does this kit fit?

This kit is built for manual AC systems without rear A/C vents in the center console and fits many 2003–2006 Chevy and GMC models. It replaces multiple OEM references, so confirm fit with your vehicle's current part number before ordering. Compatibility covers full‑size trucks and SUVs where the resistor mounts with a four‑hole flange on the lower passenger side.

• Compatible models: Chevy Silverado, Avalanche, Suburban, Tahoe; GMC Sierra, Yukon/Yukon XL; Cadillac Escalade ESV/EXT (2003–2006).
• Cross references: 89019088, 973-405, 15-81086, 1581086, 22807123 and others.
• Designed for manual climate control without rear console vents (4‑hole mounting flange).

Is installation difficult and what tools do I need?

Installation is straightforward and follows the same steps as the original part: remove the mounting screws, unplug the harness, swap the resistor module and secure the new kit. No specialized tools or advanced skills are required, and the harness included avoids splicing or additional adapters in most applications.

• Locate resistor on lower passenger side of HVAC housing.
• Remove screws securing the old resistor, disconnect electrical connector.
• Install new resistor and harness, tighten screws, reconnect battery if disconnected.

What quality assurances and support come with the kit?

A-NAFTULY designs this blower motor resistor kit to meet or exceed OEM standards and subjects components to quality checks. The product ships as a complete kit and includes an 18‑month warranty plus round‑the‑clock customer assistance for troubleshooting and replacements if issues arise.

• Direct replacement that meets OEM fit and function expectations.
• 18‑month worry‑free warranty backed by 24/7 support.
• Supplied as a complete kit—resistor module plus harness—ready to install.

Who is this for: Drivers and DIY technicians who own 2003–2006 Chevrolet, GMC, or compatible Cadillac trucks and SUVs with manual AC control and no rear console vents, and who need a reliable, direct‑fit solution to restore HVAC blower speed control. This kit suits anyone wanting an OEM‑style replacement without extra modifications, plus peace of mind from a warranty and support network.
