GMC Acadia HVAC Blower Motor Resistor Guide for 2013-2018 Models
Is your Acadia's fan stuck on high or not working at all? Your blower motor resistor is the likely culprit.
- Verify if you have a first-gen (2013-17 Limited) or second-gen (2017-18) Acadia before buying.
- 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 to prevent the new resistor from failing prematurely.
- This is an easy DIY repair located under the passenger side dashboard that takes less than an hour.
Is Your 2013-2018 GMC Acadia's Fan Acting Up?
If your Acadia's climate control fan only blows on the highest setting, or if some speeds have stopped working, you're dealing with a classic symptom of a failed HVAC Blower Motor Resistor. This component is essential for controlling fan speed for both heat and A/C. When it fails, it can leave you with an all-or-nothing fan, or no fan at all. This guide covers the symptoms, part choices, and replacement details for the 2013-2018 GMC Acadia.
Important: Know Your Acadia's Generation
The 2013-2018 model years cover two different generations of the GMC Acadia, which use different parts. It is critical to order the correct resistor for your specific vehicle.
- First Generation (2013-2016) & 2017 Acadia Limited: These models use one style of blower motor resistor.
- Second Generation (2017-2018): The redesigned 2017 Acadia and subsequent models use a different part.
Always verify the part fits your exact year and model before purchasing.
Common Failure Symptoms
- Fan Only Works on High: This is the most common sign. The highest fan speed setting often bypasses the resistor, so it works even when the resistor has failed.
- Some Fan Speeds Don't Work: You might lose low or medium speeds while others still function.
- No Airflow at Any Speed: In some cases, a complete failure of the resistor can prevent the blower motor from running at all.
- Inconsistent Fan Speed: The fan speed may change on its own or cut in and out while you're driving.
- Burning Smell from Vents: An overheating resistor can produce a burning plastic smell, especially when you first turn the fan on.
Choosing the Right Aftermarket Resistor
When replacing the blower motor resistor, you have several aftermarket options. Quality can vary, so it's important to choose a reliable brand to avoid doing the job twice.
Tier 1: Recommended Brands
These brands have a strong reputation for quality and durability in the aftermarket community.
- Standard Ignition (Standard Motor Products): Known for high-quality materials and strict manufacturing standards, leading to reliable performance and long service life.
- Dorman: A well-regarded aftermarket manufacturer. Their kits often include a new wiring harness pigtail, which is a major advantage if your original connector is melted or corroded—a common issue.
Tier 2: Economy Brands
These brands are more budget-friendly, but user reviews are mixed. They may be a suitable option for a quick fix, but long-term reliability can be a concern for some users.
- Four Seasons: A very common brand for HVAC parts. Some users report years of good service, while others have experienced premature failures.
- Global Parts (GPD), Holstein: Fewer independent reviews are available for these brands, placing them in the economy category.
Pro Tip: Prevent a Repeat Failure
A failing blower motor is the number one cause of a burnt-out resistor. The old motor draws too much electricity, overheating the new resistor. Before installing a new resistor, check the blower motor. If it's noisy or hard to spin by hand, replace it at the same time. Also, check your cabin air filter. A clogged filter restricts airflow, making the system work harder and leading to excess heat.

Frequently Asked Questions (FAQ)
Can I replace the blower motor resistor myself?
Yes, this is a very DIY-friendly job. The resistor is located under the passenger-side dashboard near the blower motor. The process typically involves removing a plastic cover panel, disconnecting two wire harnesses, and removing two screws holding the resistor in place. The entire job can usually be done in under an hour with basic tools.
🎬 Watch this step-by-step walkthrough of the resistor replacement process.Can I still drive my Acadia with a bad blower motor resistor?
Yes. A bad resistor does not affect the engine's operation or safety. However, your ability to defrost the windshield or cool/heat the cabin will be severely limited, which can be a safety and comfort issue in extreme weather.
Why did my blower motor resistor fail?
The most common cause is an aging blower motor that is drawing too much electrical current, causing the resistor to overheat and burn out. Other causes include moisture intrusion from a cabin leak or a clogged cabin air filter that reduces airflow needed to cool the resistor.
Is it a 'resistor' or a 'control module'?
For vehicles with manual climate controls (knobs for fan speed), the part is a traditional resistor. For some models with automatic climate control (digital temperature display), it may be called a 'Blower Motor Control Module'. They perform the same function but operate differently. The parts are not interchangeable, so be sure to order the correct component for your vehicle's system.
