• Fan does not work on one or more speed settings.
• No air blows from the vents on any setting.
• Visible corrosion or melting on the original resistor or connector.

Installation Tips

• Disconnect the vehicle's battery before starting the installation.
• The resistor is typically located under the passenger side dashboard, near the blower motor housing.
• Inspect the original connector for signs of heat damage or melting; if damaged, use the included harness for replacement.
• Ensure a secure connection for both the resistor and the wiring harness to prevent premature failure.
