FAERSI HVAC Blower Motor Resistor Kit with Harness — Fits 2003–2006 Chevy/GMC/Cadillac, Restores Multi-Speed Control

FAERSI 89019088 is a direct-fit HVAC blower motor resistor kit with a new wiring harness that restores multi-speed blower control for 2003–2006 Chevy, GMC and Cadillac models.

This replacement kit is engineered for vehicles with manual climate controls and no rear console vents, offering a complete swap-in solution that matches OEM fitment numbers. The package includes the resistor module and a fresh harness to eliminate corroded pins and unreliable connections that cause fan speed loss. Every unit is tested before shipping and backed by a one-year warranty for added reassurance.

How does this FAERSI blower resistor restore fan speed control?

The resistor rewires the blower motor’s speed paths so the fan can run at all selectable speeds again. When the original resistor fails, certain fan speeds—often low or medium—stop working; installing this module re-establishes those circuits. It uses durable terminals and a matched resistance pack to ensure consistent airflow across settings.

• Replaces failed resistor segments to recover lost fan speeds
• Includes new harness to prevent connector corrosion issues
• Tested units to confirm electrical continuity and fit

Which vehicles and part numbers is this compatible with?

This FAERSI kit is built for manual AC systems without rear A/C vents and fits many Chevrolet, GMC and Cadillac trucks and SUVs from model years 2003–2006. It corresponds to multiple OEM references so it’s a convenient aftermarket replacement for common factory numbers. Double-check the original part number and vehicle fitment before ordering.

• Fits Chevy Silverado, Avalanche, Suburban, Tahoe (2003–2006)
• Fits GMC Sierra, Yukon, Yukon XL (2003–2006)
• Fits Cadillac Escalade ESV and EXT (2003–2006); matches OEM numbers like 89019088, 973-405, 15-81086, 22807123

What’s included and how simple is the installation?

The kit contains the blower motor resistor module and a replacement wiring harness to make the swap straightforward. The resistor is typically mounted on the lower passenger side of the HVAC housing and is accessible after removing a few screws. While it’s an aftermarket part, it installs in the factory location and uses the same mounting points for a direct replacement.

• Complete resistor module plus new harness included
• Access via lower passenger-side HVAC housing; remove a few screws
• No special tools or cutting required for standard installations

What quality measures and warranty cover this FAERSI kit?

FAERSI tests each resistor assembly for electrical performance before shipping to ensure it meets functional expectations. The materials and terminals are selected to meet or exceed OEM durability for typical use conditions. FAERSI offers a one-year warranty and customer support to address defects or failures.

• 100% tested prior to shipment for continuity and fit
• Constructed with high-grade components for reliable operation
• One-year warranty with replacement or refund options

Who is this for? This FAERSI blower motor resistor kit is for owners or technicians working on 2003–2006 Chevy, GMC and Cadillac trucks and SUVs with manual climate controls who experience partial or total blower speed loss. It’s ideal for DIYers who want a direct replacement that includes a new harness to avoid intermittent blower problems, and for shops needing a reliably tested aftermarket alternative to restore HVAC function quickly.
