Humoony Blower Motor Resistor 13598134 — OE-fit for 2007–2019 GM ATC, restores multi-speed fan, 1‑Year Warranty

The Humoony blower motor resistor 13598134 restores precise HVAC fan speed control for select 2007–2019 GM and compatible vehicles, fitting units with automatic temperature control (A/C) to regulate cabin airflow reliably.

If your vehicle’s climate control is stuck on one fan speed, blows intermittently, or stops at certain settings, a faulty blower motor resistor is a common cause. This Humoony replacement is engineered to match OE electrical and mounting points for many Chevy, GMC, Buick, Cadillac, Saturn, Saab, Pontiac, Hummer and Suzuki models. It replaces several OEM numbers (including 973-420 and 15141283) and is intended only for systems with automatic temperature control.

Which vehicles will this resistor fit?

This resistor is compatible with a broad list of GM and related models from approximately 2007 through 2019. Fitment varies by front or rear location and by vehicles equipped with automatic temperature control, so check your model and year carefully.

• Chevy: Silverado, Tahoe, Suburban, Traverse, Malibu, Equinox, Cruze, Avalanche, Camaro and more (front or rear as specified).
• GMC: Sierra, Yukon, Yukon XL, Acadia, Terrain (front or rear where noted).
• Buick/Cadillac/Saturn/Pontiac/Saab/Hummer/Suzuki: selected models and years—see full fitment table for exact positions.

How does this part restore HVAC performance?

The resistor controls blower motor speed by introducing precise resistance values so the HVAC module can cycle fan speeds smoothly. A failing resistor often leads to loss of intermediate speeds or total fan failure, and replacing it returns correct current regulation to the blower motor.

• Re-establishes multi-speed fan operation for heating and cooling.
• Protects blower motor by moderating electrical current flow.
• Designed for plug-and-play replacement where OEM matches.

What are the technical and warranty details?

Humoony’s resistor is built to meet the electrical and mounting specifications listed by OEM cross-references and replacement numbers. It’s sold with a one-year limited warranty and customer support to address any fitment or functional questions.

• Replaces part numbers like 973-420, 15141283, 13598134 and other OEM codes.
• Only compatible with automatic temperature control HVAC systems (A/C).
• Includes a 1-year limited warranty and Humoony customer assistance.

How difficult is installation and what should I check before ordering?

Installation difficulty ranges from simple to moderate depending on model and whether the resistor is located behind the glove box, under the dash, or in the rear HVAC housing. Basic hand tools and minimal mechanical skills are often sufficient; some models may require removal of trim panels or seats.

• Confirm whether your vehicle uses automatic temperature control—this part is not for manual fan controls.
• Inspect the connector and wiring for corrosion or heat damage and replace or repair wiring if needed.
• Follow vehicle-specific service manual steps to access and replace the resistor safely.

Who this is for: This Humoony blower motor resistor is for DIY drivers and professional technicians who need a dependable replacement for select GM-family and related vehicles experiencing fan speed loss or inconsistent HVAC airflow. It’s ideal if you want a direct-fit alternative to OEM units with clear part number cross-references and a one-year warranty backing.
