Chevrolet SS HVAC Blower Motor Resistor & Control Module Guide (2014-2017)
Is your Chevy SS fan speed acting up? Here’s what you need to know before replacing the blower motor resistor.
- The part is technically a 'Blower Control Module' but is sold as a 'Resistor' in the aftermarket.
- Failure is common and symptoms usually involve incorrect fan speeds or no fan operation.
- This is an easy and inexpensive DIY repair, typically taking less than 30 minutes.
- If the resistor fails repeatedly, the blower motor itself is likely drawing too much current and needs replacement.
Is it a Resistor or a Control Module?
Your 2014-2017 Chevrolet SS uses an automatic climate control system, which requires a Blower Control Module for variable fan speeds. However, in the aftermarket world, this part is commonly called a Blower Motor Resistor. They both perform the same basic function: controlling fan speed. For this guide, we will use the terms interchangeably, but know that your SS uses the more advanced module-style part.
Symptoms of a Failing Blower Motor Resistor
When this part starts to fail, the symptoms are usually obvious and directly related to the cabin fan. You will likely experience one or more of the following issues:
- Fan only works on the highest speed: This is the most classic symptom. The highest setting often bypasses the resistor entirely, getting full power from the battery.
- Fan doesn't work at all: The module can fail completely, leaving you with no airflow from the vents.
- Inconsistent or erratic fan speeds: The fan speed may change on its own, or not correspond to the setting you've selected.
- Fan is stuck on one speed: The module may fail in a way that locks the fan into a single speed that you cannot change.
- Burning smell from vents: In some cases, the module or its wiring connector can overheat and melt, which can produce a smell of burning plastic. This is a serious symptom that should be addressed immediately.
Pro Tip: Check the Blower Motor Too
A failing blower motor can draw too much electrical current, causing a new resistor or module to burn out prematurely. If you've replaced the resistor before and it failed again quickly, inspect the blower motor itself. If it's noisy or doesn't spin freely, it may be the root cause of the problem.
Choosing the Right Aftermarket Part
For the Chevrolet SS, several reputable aftermarket brands offer replacement blower motor control modules. While an OEM part is always an option, quality aftermarket parts can offer significant savings without sacrificing reliability.
- Dorman: A well-known brand that produces a wide range of aftermarket parts. Their kits often include a new wiring harness, which is a major advantage if the original connector is melted or corroded.
- Four Seasons: A brand specializing in climate control parts. They are generally considered a reliable choice for components like blower motor resistors.
- Standard Ignition (SMP), Global Parts (GPD), Holstein: These are other established brands in the aftermarket that manufacture parts for the SS. They are solid alternatives if available.
Ultimately, choosing a part from a recognized brand like Dorman or Four Seasons is a safe bet. The most critical factor is ensuring the part is listed as a direct fit for the 2014-2017 Chevrolet SS to avoid electrical issues.

Frequently Asked Questions
Is there a recall on the Chevy SS blower motor resistor?
No. While GM has issued recalls and special coverage for similar parts on other vehicles like trucks and SUVs for overheating issues, there are no active recalls or Technical Service Bulletins (TSBs) specifically for the 2014-2017 Chevrolet SS blower motor resistor.
Can I replace the blower motor resistor myself?
Yes, this is a very DIY-friendly job. The part is located behind the passenger-side glove box and is typically held in with two screws. Most owners with basic hand tools can complete the replacement in under 30 minutes.
Where is the blower motor resistor located on the Chevy SS?
It is located on the passenger side of the vehicle, behind the glove box, mounted in the HVAC housing. You will need to remove a lower kick panel or the glove box assembly to gain access.
Why did my new blower motor resistor fail already?
The most common reason for repeat failure is a problem with the blower motor itself. An old or failing blower motor can draw too much electricity, which overheats and destroys the resistor. If you replace the resistor, it's a good idea to check that the blower fan spins freely and quietly.
