Gaoyeer Blower Motor Resistor 4P1516 (15-80567) Direct-Replacement for GM Multi-Speed HVAC

Gaoyeer AC Blower Motor Resistor 4P1516 (15-80567) is a direct-replacement blower control module that restores multi-speed fan control for compatible GM trucks and SUVs.

If your vehicle’s HVAC fan only works on one speed or not at all, the blower motor resistor is often the faulty component. This Gaoyeer resistor module is designed to match OE electrical characteristics and fitment for a long list of Chevrolet, GMC, Cadillac and other GM-based models from the early 2000s, delivering reliable speed regulation and simple installation.

Which vehicles and part numbers does this resistor fit?

This resistor is engineered to replace several OE and aftermarket references so you can confirm compatibility by part number or vehicle fitment. Always verify the original resistor’s connector style and pin count before ordering to ensure a match.

• Common compatible GM models: Chevy Avalanche, Silverado, Suburban, Tahoe, Trailblazer (2003–2006), Cadillac Escalade series (2003–2006)
• Additional fitments: GMC Sierra, Yukon/XL, Envoy; Buick Rainier; Isuzu Ascender; Saab 9-7x; Oldsmobile Bravada (model years 2003–2006 where specified)
• Cross-references: 4P1516, 15-80567, 1580567, 93803636, 52413530, 89018778 and many OEM/match numbers

How does this blower resistor restore HVAC fan speeds?

The resistor controls electrical current to the blower motor so the fan runs at different speeds. When the original resistor fails, current paths are interrupted and certain fan speeds stop working; replacing it restores proper voltage regulation and multi-speed operation.

• Regulates current to the fan for stepped speed selection
• Constructed to meet or exceed factory thermal and electrical specs
• Pre-tested for stable operation and reduced risk of premature failure

Is installation difficult and where is the part located?

Installation is straightforward for most DIYers and technicians: the resistor is mounted in the HVAC housing on the lower passenger side of the vehicle. Removing a few screws and swapping the module takes minimal tools and time when you confirm connector match first.

• Location: lower passenger-side HVAC housing, accessible from under the dash
• Tools needed: common screwdrivers or small socket set
• Steps: disconnect battery (recommended), remove mounting screws, unplug harness, replace resistor, reassemble

What should I check before purchasing to avoid returns?

Because the same vehicle model can use different resistor variants depending on HVAC configuration and engine options, confirm the OE number, pin count and physical connector on your current resistor before ordering. That prevents fitment issues and saves installation time.

• Compare OE part number stamped on your old resistor with the listed cross-references
• Inspect the number of pins and shape of the wiring harness connector
• Match mounting tab positions and overall module shape for proper fit

Who this is for: This Gaoyeer blower motor resistor is intended for owners and technicians working on early-2000s GM full-size trucks and SUVs who need a reliable, cost-effective replacement for a failed HVAC fan resistor. It’s suitable for anyone comfortable performing basic under-dash repairs or a mechanic seeking a tested aftermarket module that matches common OE part numbers and restores full fan-speed control.
