Humoony Blower Motor Resistor 7-Pin 13598134 Compatible with Select 2007–2019 GM Vehicles — Direct-Fit, Multi-Speed HVAC Restore

Humoony's 7-pin blower motor resistor 13598134 is a direct-fit replacement resistor module designed to restore multi-speed HVAC blower function on select GM and related vehicles with automatic temperature control.

This blower motor resistor replaces factory part numbers such as 973-420, 15141283, and 13598134 and is intended for front or rear blower systems on compatible 2007–2019 Chevrolet, GMC, Buick, Cadillac, Saab, Pontiac, Saturn, Hummer and Suzuki models when the vehicle uses automatic climate control. It regulates blower motor current to allow fan-speed selection, helps prevent motor overheating, and is supplied with a 7-pin connector—confirm connector type and vehicle fitment before ordering.

Which vehicles will this Humoony resistor work with?

This resistor is built for many General Motors platforms and a selection of related makes across model years roughly 2007–2019. It fits models equipped with automatic temperature control; compatibility varies by model and production year, so always verify against your vehicle's connector and part number.

• Chevrolet: Silverado, Suburban, Tahoe, Traverse, Malibu, Equinox, Avalanche, Camaro, Cruze and others (select years).
• GMC: Sierra, Yukon/Yukon XL, Acadia, Terrain (select years).
• Buick/Cadillac/Other: Enclave, LaCrosse, CTS, Escalade, SRX, Saab 9-5, Hummer H2, Pontiac Torrent, Saturn Outlook/Vue, Suzuki XL-7.
• Only for systems using automatic climate control and a 7-pin blower connector, not compatible with 5-pin plugs.

How does this resistor restore blower fan control?

The resistor module adjusts electrical resistance in the blower motor circuit, enabling different fan-speed settings on vehicles that use resistive control. When the original resistor fails, common symptoms include loss of some fan speeds or no blower operation.

• Re-establishes multi-speed blower operation by changing current flow to the motor.
• Designed to reduce current peaks that can overheat the blower motor.
• Direct-fit 7-pin connector matches vehicles listed under compatible models and replace numbers.

What should I check before buying and installing?

Confirm your vehicle’s year, model, and whether it uses automatic temperature control. Inspect your existing resistor plug—this Humoony unit uses a 7-pin connector and will not fit 5-pin systems. If unsure, compare the replace numbers and pictures to your original part.

• Verify OEM replace numbers: 973-420, 15141283, 13598134 and variants listed in product details.
• Ensure the vehicle climate system is automatic temperature control (A/C automatic mode).
• Match the connector shape to the product photos; 7 pins are required for compatibility.

What warranty and support does Humoony provide?

Humoony backs this blower motor resistor with a one-year warranty and customer support to help resolve installation or fitment issues. Reach out to Humoony if you experience functional defects or need guidance verifying fitment.

• 1-year limited warranty covers manufacturing defects under normal use.
• Customer support available for fitment questions and troubleshooting.
• Return or replacement options handled per Humoony warranty terms.

Who is this product for? This Humoony blower motor resistor is aimed at DIY owners, mechanics, and fleet maintainers working on compatible GM and related vehicles (2007–2019) that have lost fan-speed control and use automatic temperature control with a 7-pin blower connector. If your vehicle matches the listed models and connector type, this direct-fit replacement offers a cost-effective way to restore HVAC blower performance without replacing the entire motor.
