The blower motor resistor plays a pivotal role in managing the electrical current that powers the blower motor, allowing you to adjust the fan speed inside your Chevy Trax. Over time, this component can wear out or fail, leading to issues like limited fan speed settings or no airflow at all. For drivers and DIY enthusiasts alike, having a clear understanding of the resistor’s location can save time and money by simplifying diagnostics and repairs.
In the following sections, we’ll explore the general placement of the blower motor resistor within the 2018 Chevy Trax and discuss why its location matters when troubleshooting HVAC problems. Whether you’re preparing for a repair or just curious about your vehicle’s inner workings, this guide will equip you with the foundational knowledge needed to tackle blower motor resistor issues confidently.
Locating the Blower Motor Resistor on a 2018 Chevy Trax
The blower motor resistor on the 2018 Chevy Trax is typically situated within the HVAC system, close to the blower motor itself. This location allows it to regulate the electrical current flowing to the blower motor, adjusting the fan speed accordingly. On the Trax, you will find the resistor mounted on the HVAC housing, usually accessible from the passenger side footwell or under the glove compartment.
To locate it precisely:
- Remove the passenger side lower dash panel or kick panel to gain access.
- Look for a small rectangular component with an electrical connector plugged into it.
- The resistor is often secured with screws or bolts to the HVAC housing.
- It is positioned near the blower motor fan assembly, identifiable by its multiple wire leads.
Because the resistor handles significant current and heat, it is designed with a metal heat sink or fins for cooling. This physical characteristic can help differentiate it from other components in the area.
Steps to Access and Inspect the Blower Motor Resistor
Accessing the blower motor resistor on a 2018 Chevy Trax involves a few careful steps to avoid damage to surrounding components:
- Disconnect the battery: To ensure safety when working with electrical components.
- Remove the passenger side lower trim panel: This panel is usually held by clips or screws; gently pry or unscrew it.
- Locate the blower motor resistor: As described, it should be attached to the HVAC housing with an electrical connector.
- Disconnect the electrical connector: Press the tab and carefully pull the plug free.
- Remove the mounting screws or bolts: Use the appropriate screwdriver or socket wrench.
- Extract the resistor: Pull it out gently to avoid damaging the wiring or housing.
Once removed, inspect the resistor for signs of damage such as corrosion, burnt areas, or broken connectors. A faulty resistor often manifests as inconsistent blower speeds or complete failure of the fan to operate at certain speeds.
Common Symptoms of a Faulty Blower Motor Resistor
When the blower motor resistor starts to fail, several symptoms can alert you to its condition:
- Blower fan only works on the highest speed setting.
- No response or inconsistent operation at lower fan speeds.
- Intermittent blower motor operation.
- The blower motor does not operate at all.
- Visible damage or burnt smell near the resistor area.
These issues arise because the resistor controls the voltage supplied to the blower motor, and any failure results in improper current regulation.
Replacement Considerations and Compatibility
When replacing the blower motor resistor on a 2018 Chevy Trax, it is critical to use a part that matches the original specifications to ensure proper function and longevity. Using aftermarket or incompatible resistors may result in improper blower motor speeds or premature failure.
