FAERSI HVAC Blower Motor Resistor Kit with Harness for Chevy/GMC 2003–2006 — Direct-Fit, Pre-Tested

FAERSI 15-81773 is a direct-fit HVAC blower motor resistor kit with harness engineered to restore proper blower motor speed control on compatible Chevy and GMC vehicles.

This replacement kit includes the blower motor resistor module and wiring harness designed to match OE fitment for a variety of 2003–2006 GM trucks and SUVs. It addresses common symptoms like loss of certain fan speeds or inconsistent airflow, and it ships fully tested. The assembly is intended as a straightforward swap for the factory part, offering a more budget-friendly alternative while meeting or exceeding typical OEM performance expectations.

How will this resistor kit fix my blower's fan speed problems?

When a blower resistor fails, some fan speeds stop working or the blower operates only at high speed. Installing this kit restores the resistor network and the electrical connections that control multiple fan speed settings, returning normal HVAC airflow control.

• Replaces worn or burned resistor circuits that disable mid-range speeds.
• Includes harness to renew corroded or damaged connector wiring.
• Restores full range of fan speeds instead of only high or off.
• Pre-tested unit reduces likelihood of immediate replacement failure.

Which vehicles and part numbers are compatible with FAERSI 15-81773?

This kit is compatible with many Chevy and GMC full-size trucks and SUVs from the early 2000s. Confirm fitment by checking your vehicle year, make, and model against the listed OEM cross-reference numbers to ensure a correct match before purchasing.

• Common fits: Chevy Silverado, Tahoe, Suburban, Avalanche, Trailblazer EXT (2003–2006).
• Common fits: GMC Sierra, Envoy, Yukon, Yukon XL, and similar GM platforms.
• Cross-reference OEM numbers: 89018778, 89019351, 19260762, RU-631 and others.
• Use vehicle lookup or part numbers for precise confirmation.

Is installation difficult and what tools are typically required?

Installation is generally simple for anyone comfortable working under the dash or removing a few screws in the lower passenger-side footwell. The resistor mounts into the blower housing and the harness plugs into the factory connector; most jobs take less than an hour with basic tools.

• Typically requires a Phillips screwdriver and/or small socket set.
• Access is usually through the lower passenger-side kick panel or glovebox area.
• Disconnect the battery briefly for safety when replacing electrical components.
• Follow vehicle repair manual or a trusted online guide for step-by-step help.

What quality assurances and warranty coverage come with this part?

The FAERSI resistor kit is manufactured to meet or exceed common OEM standards and is functionally tested prior to shipping. While it is an aftermarket replacement rather than a factory part, the product is backed by a one-year limited warranty against defects and workmanship.

• Each unit tested for electrical continuity and operation before dispatch.
• High-grade materials used for extended service life compared with cheap clones.
• One-year warranty covers free replacement or refund for qualifying defects.
• Customer support available for fitment questions and troubleshooting.

Who this is for: vehicle owners or technicians working on early-2000s GM trucks and SUVs who need a reliable, direct-fit blower motor resistor replacement with an included wiring harness. Ideal for DIY installers wanting a cost-effective repair, fleet maintenance professionals, and anyone troubleshooting inconsistent HVAC fan speeds. Always verify compatibility using your vehicle details and the provided OEM cross-reference numbers before ordering.
