GMC Yukon 2000-2007 HVAC Blower Motor Resistor & Control Module Guide
Fix your Yukon's fan speed problems by choosing the right replacement part for your specific climate control system.
- Verify if your Yukon has manual knobs or automatic (digital) climate control; they use different, non-interchangeable parts.
- Always inspect the wiring connector for melting or corrosion and replace it if damaged to prevent repeat failure.
- The most common symptom of failure is the fan only working on the highest speed setting.
- Consider replacing the blower motor at the same time if it's old or noisy, as a failing motor is the primary cause of resistor burnout.
Is Your Yukon's Fan Acting Up?
A faulty blower motor resistor is one of the most common issues for the 2000-2007 GMC Yukon. The symptoms are usually very clear and point directly to this part. The most frequent complaint is the fan only working on the highest setting. This happens because the high setting is wired to bypass the resistor, getting power directly. Other signs include the fan not working on some or all speeds, or speeds changing on their own.
Important: Manual vs. Automatic Climate Control
Before buying a part, you MUST know if your Yukon has manual or automatic climate controls. Manual controls use simple knobs to adjust temperature and fan speed. Automatic controls have a digital display and "Auto" button. They use different parts that are not interchangeable.
- Manual Controls: Uses a Blower Motor Resistor.
- Automatic Controls: Uses a Blower Motor Control Module. This part is more complex and expensive.
Known Issues for 2000-2007 GMC Yukon
General Motors issued a Special Coverage Adjustment (Bulletin No. 10240A) for many 2003-2006 Yukons with manual HVAC systems. This was not a formal recall but an extended warranty program covering the blower motor resistor and its wiring connector for 10 years or 150,000 miles. The issue involves the electrical connector overheating and melting due to high current draw or contamination from moisture. This can cause a burning plastic smell, smoke, or make the blower stop working. Even if your vehicle is outside the warranty period, this highlights a critical point: always inspect the wiring connector when replacing the resistor. If it looks burnt, corroded, or melted, you must replace it with a new pigtail harness to prevent the new resistor from failing quickly.

For this specific part, aftermarket quality is generally considered very good, and often a better value than OEM. Many aftermarket kits, especially from brands like Dorman, include a new wiring harness, which is a common failure point.
Brand Quality Tiers:
- Premium Brands (ACDelco, Dorman): ACDelco is the original GM parts supplier and offers a direct fit and function. Dorman is a leading aftermarket brand that often engineers solutions to common OEM problems and frequently includes the necessary replacement wiring pigtail.
- Standard Brands (Four Seasons, Standard Ignition, Holstein): These brands provide reliable, quality replacements that meet or exceed OEM specifications and are a popular choice for a balance of price and performance.
- Economy Brands (URO Parts, True Tech, Global Parts): These offer a budget-friendly solution. While functional, they may not have the same long-term durability or include extras like a new wiring harness.
Pro Tip: Replace the Blower Motor, Too?
The number one cause of repeat resistor or module failure is a worn-out blower motor. As the motor ages, it has to work harder and draws more electrical current. This extra current overloads the resistor, causing it to overheat and burn out. If your blower motor is noisy, doesn't spin freely, or is the original unit with high mileage, it's wise to replace it at the same time as the resistor to prevent having to do the job again in a few months.
Cost of Replacing a Blower Motor Resistor

| New OEM Resistor/Module | $50 - $260 |
| Shop Labor | $50 - $132 |
Frequently Asked Questions (FAQ)
Where is the blower motor resistor located on a 2000-2007 Yukon?
The blower motor resistor (or module) is located under the passenger side of the dashboard, mounted directly on the HVAC housing near the blower motor itself. You will need to remove a plastic cover panel to access it.
Is this a difficult part to replace myself?
No, this is a very easy DIY job. It typically takes less than 30 minutes and requires only basic hand tools, 🎬 Follow this step-by-step walkthrough to replace your resistor. like a 5.5mm or 7/32" socket. The part is held in by two screws and has one or two electrical connectors.
Why do some replacement parts look different or have a different number of pins?
This is usually due to the difference between manual and automatic climate control systems. A resistor for a manual system will have a different connector than a control module for an automatic system. Always verify the part fits your specific Yukon trim (SLT, Denali, etc.) and control type before ordering.
Do I need to replace the wiring harness with the resistor?
You must inspect the harness connector for any signs of melting, browning, or corrosion. If any damage is visible, you must replace the connector pigtail. Failure to do so will cause the new resistor to fail prematurely. Many aftermarket kits include a new pigtail for this reason.
