X4XZ HVAC Blower Motor Resistor Control Module — OE 15141283 / 68029736AA, Copper Contacts & Aluminum Columns

X4XZ HVAC blower motor resistor control module (OE 15141283 / 68029736AA / 4P1594) restores variable fan speeds and reliable cabin airflow for compatible GM, Dodge, Chrysler and other vehicles.

This replacement blower motor resistor control module is engineered to bring back full fan-speed control when your HVAC system is stuck on one speed, fails to operate on certain settings, or produces weak airflow. Built with durable copper contacts and aluminum columns, the unit resists heat and wear, offers stable conductivity, and matches original-equipment fitment for a range of models. The module ships as a single unit and carries multiple OE cross-reference numbers for straightforward identification.

Which vehicles will this blower motor resistor work with?

The X4XZ module covers many GM and FCA platforms across model years primarily from the mid-2000s through the mid-2010s. It lists multiple OE numbers so you can match it to the factory part in your vehicle and confirm compatibility visually against the second image provided.

• Chevrolet: Silverado 1500/2500/3500, Suburban, Camaro, Captiva Sport, Equinox, Tahoe (range 2007–2014 depending on model)
• Cadillac: Escalade, CTS (2007–2015), plus select GMC Sierra, Yukon and Terrain models
• Dodge/Chrysler: Grand Caravan, Charger, Chrysler 300, Town & Country (2008–2016 ranges)
• Other brands: Buick Enclave/Verano, Opel/Vauxhall Insignia and Zafira, Lancia Voyager, and select International trucks

How does this part improve HVAC performance?

When a resistor module fails it often causes the blower to run only at one speed, stop responding to speed controls, or reduce air output. Replacing the faulty control module restores the variable resistances the fan motor needs to run at different speeds, improving responsiveness and airflow distribution through vents.

• Restores multi-speed fan control rather than single-speed operation
• Reduces intermittent fan function and improves consistent airflow
• Prevents overheating and electrical damage by maintaining proper current flow

What materials and design features ensure durability?

The X4XZ blower resistor uses robust metal interfaces and a heat-tolerant structure to withstand repeated thermal cycles inside the HVAC housing. Those materials help lessen corrosion and wear, so the module maintains reliable electrical contact and long-term performance.

• Copper contact points for superior conductivity and low-resistance signal transfer
• Aluminum column construction for heat dissipation and impact resistance
• Factory-style geometry for accurate fit and straightforward installation

What’s included and what after-sales support is provided?

Each order contains one HVAC blower motor resistor control module engineered to match OE numbers 15141283, 13598134, 3626414C1, 68029736AA, 15-81638, and 4P1594. The unit is designed for direct replacement without modification, and X4XZ provides customer service and a one-year product warranty to address installation or quality concerns.

• Package: 1 × HVAC blower motor resistor control module
• OE cross-references included for part matching before purchase
• 24-hour customer support and one-year product service for peace of mind

Who is this for: This replacement module is aimed at DIY mechanics, independent repair shops, and owners of compatible Chevrolet, GMC, Cadillac, Dodge, Chrysler, Buick, Opel/Vauxhall, Lancia, and International vehicles experiencing HVAC blower speed issues. If your fan runs only on one speed, fails to change speeds, or airflow is weak, this X4XZ unit is a cost-effective repair option that restores factory-like blower control when properly matched to your vehicle’s OE number.
