To find it, you'll likely need to:
1. Remove the glove compartment: This usually involves removing screws and possibly unclipping it. Consult your owner's manual or a repair manual specific to your year and model for the exact procedure.
2. Look behind the glove box: Once the glove box is out, the resistor should be visible. It's often a small, rectangular or square-shaped component attached to the HVAC housing. It may be wired directly to the blower motor assembly.
Important Note: It's always advisable to disconnect the negative battery terminal before working on any electrical component in your vehicle to prevent accidental short circuits.
