How does performance compare to the original equipment motor?

KAX designs this blower motor to meet OE fit, form, and performance expectations so airflow volume, sound levels, and electrical draw match factory behavior. The motor’s 220W rating and 3800 RPM speed provide sufficient airflow for heater and A/C cores while the plastic fan cage delivers lightweight, corrosion-resistant operation. Quality control targets consistent electrical characteristics to avoid charging or control module issues.

• Rated at 220W and 3800 RPM for consistent airflow
• Clockwise rotation and two-port male connector for correct wiring orientation
• Plastic fan cage reduces corrosion and helps maintain balance and quiet operation
• Manufactured to OE-equivalent tolerances for straightforward replacement

What should I know about installation and electrical connections?

Installation is typically a dealer- or DIY-level job depending on vehicle model; blower motors are usually accessed from under the dash or behind glovebox panels. This KAX unit includes the resistor with the fan cage on the front side, and the two-port male connector matches the factory harness on most compatible models. Verify battery isolation and test the new unit at low speed before reassembly.

• Disconnect the negative battery terminal before working on HVAC circuits
• Confirm connector gender and two-port pinout match your factory harness
• Test blower operation at multiple speeds before reinstalling panels
• Use vehicle-specific service manual torque and removal procedures to avoid damage
