IVONNEY Blower Motor Resistor Kit for Chevy & GMC 2003–2006 — Direct-Fit with Harness, Restores Fan Speeds

IVONNEY 89019088 blower motor resistor kit with harness replaces the factory resistor to restore variable fan speeds for select 2003–2006 GM trucks and SUVs. If your Chevrolet or GMC’s blower only runs on one speed, doesn’t respond to the fan control, or stops working entirely, the resistor module is often the reason. This kit includes the resistor assembly and a matching harness designed as a direct-fit replacement for manual HVAC systems without rear console vents, making repair straightforward and affordable without removing the entire blower motor.

How will this kit fix my fan speed problems?

The resistor controls the different blower motor speeds by regulating current to the fan motor. Replacing a failed resistor restores the multiple speed settings and resolves issues like constant high-speed operation or no air at all.

• Replaces worn or burned resistor elements that prevent speed changes.
• Includes harness for reliable electrical connections and proper fit.
• Targets vehicles with manual AC controls and no rear center-console vents.

Which vehicles and part numbers is this compatible with?

This IVONNEY kit is made to match the fit and function for many GM trucks and SUVs produced 2003–2006. It corresponds to several reference part numbers so you can confirm fitment before buying.

• Fits Chevy Silverado (1500, 1500 HD, 2500, 2500 HD, 3500, 3500 HD) 2003–2006.
• Compatible with Avalanche, Suburban, Tahoe, Sierra, Yukon, Yukon XL, Escalade ESV/EXT with manual controls.
• Replaces part numbers 89019088, 973-405, 15-81086, 22807123.

What does installation look like and how hard is it?

Installation is designed to be plug-and-play with minimal tools: remove a few screws, unplug the old resistor, and secure the new unit. The resistor sits on the lower passenger-side dash and is easily reached after removing the access screws.

• No cutting or splicing required when matched to correct model years.
• Typical install time: 15–30 minutes for a homeowner or technician.
• Step-by-step visual access—located behind the glove area on many models.

What materials, quality checks, and warranty come with this part?

The IVONNEY resistor module uses aluminum and durable plastics to handle heat and current, built to meet or exceed OEM expectations for longevity. Each unit is inspected and tested before shipment to reduce returns and ensure reliable operation.

• Aluminum heat-sink and molded plastic housing for long-term performance.
• Low power draw design and factory-style connector harness included.
• Backed by a 1-year limited warranty and support for replacement if defective.

Who is this for? If you own a 2003–2006 Chevy or GMC truck or SUV with manual climate controls and no rear console vents and you are experiencing limited or no blower motor speeds, this IVONNEY 89019088 blower motor resistor kit is a direct-fit replacement option. It’s suitable for DIY installers, independent mechanics, and fleet maintenance teams who want an economical repair that restores full HVAC fan control without replacing the blower motor assembly.
