Chevrolet SSR Blower Motor Resistor: Function, Symptoms, and Replacement
If your SSR's fan speeds are acting up, the blower motor resistor is the likely culprit.
- The most common symptom of failure is the fan only working on the highest speed setting.
- Always inspect the wiring connector for melting; it's best to buy an aftermarket kit that includes a new harness.
- This is a simple DIY job for most owners, located under the passenger side dashboard.
- A failing blower motor can cause the new resistor to fail, so consider replacing both on a high-mileage SSR.
Is your Chevrolet SSR's fan acting strange?
If your 2003-2006 Chevrolet SSR's climate control fan only works on the highest setting, won't switch speeds, or doesn't work at all, a failed blower motor resistor is the most common reason. This is a frequent issue on many vehicles from this era, including the SSR and its platform-mates like the Chevy Trailblazer. The resistor is a simple part, but when it fails, it can make your ride uncomfortable.
Symptoms of a Failing Blower Motor Resistor
Watch for these clear signs of a bad blower motor resistor in your SSR:
- Fan Stuck on High Speed: The most classic symptom. The fan works on the highest setting but not on any of the lower speeds. This happens because the high setting bypasses the resistor entirely.
- Some Fan Speeds Don't Work: You might lose one or more of the lower or medium speeds while others still function.
- No Fan at All: If the resistor fails completely, it can cut power to the blower motor, meaning no air will come from your vents.
- Burning Smell: In some cases, the resistor or its wiring connector can overheat and melt, producing a plastic burning smell from the vents. 🎬 Watch this video to see common blower motor resistor symptoms. This is a serious sign and should be addressed immediately.
Check the Wiring Harness
When replacing the resistor, it is critical to inspect the wiring connector that plugs into it. Overheating from a failing resistor often melts the connector. Many aftermarket kits include a new harness connector for this reason. If your connector is melted or shows signs of heat damage, you must replace it to prevent the new resistor from failing prematurely.
Choosing an Aftermarket Replacement Part
For the 2003-2006 SSR, you have options between OEM (Original Equipment Manufacturer) and aftermarket parts. While OEM parts are a direct match, quality aftermarket parts offer a significant cost saving and are readily available. Brands like Dorman and other "Replacement" tier parts often come as a kit including the resistor and a new wiring pigtail, which is a smart purchase. Given the age of the vehicle and the simplicity of the part, a quality aftermarket resistor is a practical and cost-effective choice for most owners.

A blower motor resistor often fails because the blower motor is old and drawing too much electrical current, causing the resistor to overheat. If you replace the resistor but not an aging blower motor, the new resistor may fail again quickly. If your SSR has high mileage, it's wise to check the blower motor and consider replacing it at the same time as the resistor for a long-lasting repair.

Frequently Asked Questions
Where is the blower motor resistor located on a 2003-2006 Chevy SSR?
The blower motor resistor is located on the passenger side of the vehicle, under the dashboard, near the blower motor itself. You will need to remove a lower trim panel to access it.
Is replacing the blower motor resistor a DIY job?
Yes, for most people with basic tools, this is a very feasible DIY repair. It involves removing a few screws and disconnecting electrical connectors. 🎬 Follow this step-by-step guide for replacing the resistor yourself. The most complex part might be splicing in a new wiring harness if the old one is melted, which requires wire strippers and crimpers.
Are there any recalls for the SSR blower motor resistor?
There are no specific safety recalls for the Chevrolet SSR's blower motor resistor. However, GM did issue recalls and special coverage adjustments for similar problems on other trucks from the same era, like the Silverado and Trailblazer, for overheating connectors. This highlights how common this issue is on GM vehicles of this period.
Should I buy a kit with the wiring harness?
Yes, it is highly recommended. The wiring connector is a common failure point and often melts along with the resistor. Buying a kit that includes the resistor and a new connector pigtail ensures you have everything needed for a complete and lasting repair.
