2017 Cadillac XT5 HVAC Blower Motor Resistor & Control Module Guide
Restore control over your XT5's cabin fan speed when it acts up or stops working completely.
- Symptoms like no fan or fan stuck on high are classic signs, but on the 2017 XT5, also be aware of a TSB for the main HVAC control module which can cause similar issues.
- This part is a 'Blower Control Module,' not a simple resistor, to accommodate the XT5's variable-speed automatic climate control.
- Replacement is DIY-friendly and can be done in under an hour with basic tools; the part is located behind the glove box.
- A failing blower motor can damage the new resistor; consider replacing both on a high-mileage vehicle.
Is Your Cadillac XT5's Fan Acting Up?
If the fan for your heat or air conditioning has stopped working, only runs on the highest setting, or changes speed randomly, the blower motor resistor is a likely culprit. This is a common failure point on many vehicles. However, for the 2017 XT5, there are other potential issues with similar symptoms that are important to know about before you buy parts.
Symptoms of a Failing Blower Motor Resistor
A bad blower motor resistor in your XT5 will make itself known through the fan's behavior. You will likely experience one or more of these issues:
- Fan Only Works on High: The fan won't work on lower settings but blasts at full speed when turned to max.
- No Fan at All: No air comes from the vents at any speed.
- Erratic Fan Speed: The fan speed changes on its own without you touching the controls.
- Intermittent Operation: The fan works sometimes and then quits unexpectedly.

For the 2017 XT5, other problems can mimic a bad blower motor resistor. Some owners have reported a total loss of HVAC control, sometimes after a battery failure or jump-start. 🎬 Watch: How to reset the HVAC module after a fault Before replacing the resistor, be aware of these official GM service bulletins:
- Service Update 17128: GM identified that some 2017 XT5s were built with a faulty HVAC control module. This can cause the system to become unresponsive, even though the display shows your inputs. 🎬 See this troubleshooting guide for unresponsive XT5 climate controls The fix is to replace the control module, which is a different part than the blower resistor.
- TSB N212353840: This bulletin notes that a leaking HVAC drain hose can allow water to enter and damage the Body Control Module (BCM), leading to a wide range of strange electrical problems.
If your entire climate control interface is dead or acting strangely, the problem may be more complex than just the blower resistor.
Choosing the Right Aftermarket Replacement
When shopping for a new aftermarket blower motor resistor for your XT5, you'll find several brands available. While OEM is always an option, quality aftermarket parts can offer significant savings. Here’s a look at the available brands.
- Standard Ignition (SMP): Often considered a top-tier aftermarket brand, Standard Ignition provides parts that are well-regarded for their quality and reliability. Forum users often mention using their parts with good results. This is a solid choice for a dependable repair.
- Four Seasons: This brand offers a budget-friendly option. While some users find their parts to be exact replicas that work well, others in the wider auto community consider them to be a re-boxer of parts with inconsistent quality. It can be a good value, but may not have the longevity of a premium brand.
- Holstein: Holstein promotes its parts with an impressive 3-year/36,000-mile warranty and claims a very low failure rate. However, direct user reviews are scarce and sometimes negative, with at least one forum user reporting a very poor experience with the brand.
Cost Comparison for 2017 Cadillac XT5 Blower Motor Resistor
| Part Type | Price Range |
|---|---|
| New Aftermarket (Four Seasons, Holstein, Standard) | $56.81 - $94.35 |
| New OEM (ACDelco/GM Genuine Parts) | $150 - $250 (estimated) |
| Shop Labor for Installation | $100 - $150 |
Pro Tip: Replace the Blower Motor Too?
A failing blower motor can draw too much electrical current, which overheats and destroys the new resistor. If your XT5 has high mileage, consider replacing the blower motor at the same time as the resistor 🎬 Watch: DIY walkthrough for replacing a noisy blower motor to prevent a repeat failure.
Frequently Asked Questions
Where is the blower motor resistor located on a 2017 Cadillac XT5?
The blower motor resistor (module) is located in the passenger-side footwell, behind the glove box. It is mounted directly next to the blower motor itself.
Can I replace the blower motor resistor myself?
Yes, this is a DIY-friendly repair for most people. It typically involves removing a lower dash panel and/or the glove box to gain access. The part is usually held in with one or two screws and has a single electrical connector. Basic hand tools are all that's required.
Is there a recall on the 2017 Cadillac XT5 for HVAC problems?
No, there are no specific recalls for the blower motor resistor on the 2017 XT5. However, there is a service update (17128) for a related HVAC control module that can cause similar symptoms.
What's the difference between a blower motor resistor and a module?
A traditional resistor uses simple electrical coils to create a few set fan speeds (like Low, Medium, High). A blower motor control module, like the one in your XT5, is a more advanced electronic component that allows for fully variable fan speeds, which is necessary for automatic climate control systems. The terms are often used interchangeably by parts stores.
