2012-2017 Buick Verano HVAC Blower Motor Resistor: A Complete Guide
If your Verano's fan is stuck on high or won't change speeds, this is the guide you need.
- The most common symptom of failure is the fan being stuck on the highest speed.
- Always inspect the wiring connector for melting or corrosion; replace it if damaged.
- Replacement is a straightforward DIY job located behind the passenger glove box.
- Quality aftermarket brands like Dorman or Standard Ignition are cost-effective alternatives to OEM.
Is Your Buick Verano's Fan Acting Up?
A common issue for Buick Verano owners is a problem with the climate control fan. You might find the fan is suddenly stuck on the highest setting and won't turn down, or that some of the lower speeds don't work at all. This problem points directly to a failed HVAC blower motor resistor. This part is responsible for every fan speed except the highest one, which is why 'high' is often the only speed that works 🎬 See why your fan is stuck on high in this video. when the resistor burns out.
Check the Blower Motor and Connector First
Before you replace the resistor, it's a good idea to inspect the blower motor itself. A worn-out blower motor can draw too much electricity, causing the new resistor to fail prematurely. Also, carefully check the resistor's electrical connector for any signs of melting, browning, or corrosion. If the connector is damaged, you must replace it along with the resistor. Many aftermarket kits include a new connector pigtail for this reason.
Symptoms of a Failing Blower Motor Resistor
The signs of a bad resistor in your Verano are usually very clear. Here’s what to look for:
- Fan Stuck on High Speed: This is the most common symptom. The highest fan setting bypasses the resistor, so it will still work even when the resistor has failed.
- Some Fan Speeds Don't Work: You may lose one or more of the lower or medium speeds while others still function.
- No Air From Vents: In some cases, the resistor can fail completely, preventing the fan from working on any speed.
- Intermittent Fan Operation: The fan may work sometimes and not others, or its speed might change on its own.
Choosing the Right Aftermarket Resistor
For the 2012-2017 Buick Verano, you don't need to buy an expensive OEM part. Aftermarket brands offer reliable quality at a much lower price. The key is to choose a reputable brand and consider a kit that includes a new wiring harness if yours shows any damage.
| Brand Tier | Brands | Notes |
|---|---|---|
| Standard Replacement | Dorman, Standard Ignition (SMP), Four Seasons | These are well-known brands that offer direct-fit replacements. Dorman often sells kits that include a new wiring harness pigtail, which is a smart choice if your original connector is melted or corroded. Standard Ignition is also widely regarded as a quality aftermarket option. |
| Economy | Global Parts (GPD), Holstein, various store brands | These brands provide a functional replacement at the lowest cost. They are a good option for budget-conscious repairs, but be sure to inspect the part for quality before installation. |
Known Issues, Recalls, or TSBs
There are no active recalls from the NHTSA specifically for the HVAC blower motor resistor on the 2012-2017 Buick Verano. A GM Preliminary Information bulletin (PIE0284) was issued for a 'whine or growl' noise from the blower motor on 2013-2014 models, but this concerns the motor itself, not the resistor. The primary known issue, based on owner reports, is the potential for the wiring connector to overheat and melt, which requires replacement.
Easy DIY Replacement
Replacing the blower motor resistor is a job most DIYers can handle in under an hour. The part is located in the passenger footwell area, usually accessible by removing the glove box or a lower dash panel. You'll typically only need basic hand tools like a screwdriver or a small socket set.

Where is the blower motor resistor located on a 2012-2017 Buick Verano?
The blower motor resistor is located on the passenger side of the vehicle, underneath the dashboard and typically mounted in the HVAC housing near the blower motor itself. You will likely need to remove the glove box to access it.
Why does my fan only work on the highest speed?
The highest fan speed setting gets power directly from the battery, bypassing the resistor. All lower speeds must go through the resistor to reduce the electrical current. When the resistor fails, only the direct, high-speed connection still works.
Do I need to replace the blower motor at the same time?
Not necessarily, but it's a good idea to check it. A failing blower motor can draw too much current and burn out the resistor. If the motor is noisy or spins with difficulty, you should replace both parts to avoid having the new resistor fail again.

Yes, it is generally safe to drive. The failure of the resistor does not affect the engine's performance or critical safety systems. However, your ability to defrost the windshield could be limited, which can be a safety hazard in certain weather conditions.
