Heater / Blower Resistor - Denso - DRS09020

The blower resistor is typically located near the blower motor, often behind the glove box or under the dashboard.

You'll likely need basic hand tools, such as a screwdriver, pliers, and possibly a socket set. A multimeter can be helpful for diagnosing electrical issues.

The difficulty can vary. It's generally a straightforward process, but it requires some mechanical knowledge and access to the resistor.

No. The resistor only controls fan speed. Other issues, such as a faulty blower motor, could be the cause.

While other brands might offer similar products, ensure they are compatible with your vehicle's model and year. Using the Denso DRS09020 ensures a direct fit and compatibility.

If the blower fan only works on one speed or not at all, or if the speed is erratic, the resistor is likely faulty.

You can find the OE number in your vehicle's service manual or by checking the original part itself.

Check the fuse related to the blower motor. If the fuse is good, the resistor may be faulty.

The resistor is likely faulty and needs replacement.

Inspect the resistor for damage or corrosion. Replace if necessary.

Check the wiring connections to the resistor and ensure they are secure. Replace the resistor if the issue persists.
