A-NAFTULY Blower Motor Resistor Kit with Harness for 2003–2006 Chevy GMC Cadillac — Direct-Fit OEM Replacement

The A-NAFTULY 89019088 blower motor resistor kit with harness restores fan-speed control for 2003–2006 Chevrolet, GMC and Cadillac models equipped with manual AC and no rear console vents.

If your truck or SUV’s HVAC blower only works on one speed, refuses to run, or cycles unpredictably, a failed blower motor resistor is often the cause. This kit contains a direct-fit resistor module and matching harness built to meet OEM dimensions and electrical requirements, letting you replace the old unit quickly and get the ventilation system back to proper operation.

Which vehicles and configurations does this resistor kit fit?

This resistor assembly is made for manual climate-control models without rear A/C console vents and uses the 4-hole mounting flange style. It’s compatible with many 2003–2006 heavy-duty and passenger GM vehicles.

• Chevrolet Silverado 1500/1500 HD/2500/2500 HD/3500/3500 HD (2003–2006)
• Chevrolet Avalanche 1500/2500, Suburban 1500/2500, Tahoe (03–06)
• GMC Sierra 1500/1500 HD/2500/2500 HD/3500/3500 HD, Yukon/Yukon XL (03–06)
• Cadillac Escalade ESV/EXT (2003–2006)

How do I know if the blower resistor is the problem?

Typical symptoms include the blower running only on high, operating at a single speed, or not running at all. Visual inspection may reveal a burnt or cracked resistor pack; otherwise electrical testing confirms an open circuit in the resistor pathways.

• Fan works only on one speed (often high) — common resistor failure sign
• Intermittent blower operation or no airflow at any setting
• Visible heat damage, corrosion, or broken terminals on the old resistor
• Simple multimeter continuity test can verify open circuits

Is the A-NAFTULY kit easy to install and will it fit like OEM?

The kit is designed as a direct replacement that meets or exceeds OEM fit and performance specifications. Installation is straightforward: access the resistor on the lower passenger side, remove the mounting screws and connector, then install the new assembly using the same fasteners.

• Direct-fit replacement for OE part numbers including 89019088 and equivalents
• Plug-and-play harness included — no splicing required
• Typically requires only a screwdriver; no special tools or skills
• Manufactured and tested to match OEM electrical characteristics
