When to Replace

• HVAC fan only operates on the highest speed setting.
• Blower fan speed cannot be adjusted or works intermittently.
• No air is blowing from the vents even when the fan is audible.
• A burning plastic smell is present near the passenger side dashboard.

Installation Tips

• The module is typically located in the passenger-side footwell, mounted to the HVAC housing.
• Always disconnect the vehicle's negative battery terminal before starting the installation.
• Use the included wiring harness to replace the original connector, as overheating and corrosion on the original harness is a common point of failure.
• Before installing the new module, inspect the blower motor. A worn or failing motor can draw excessive current and cause repeated module failure.
