Notice: Do not allow the metal coils of the blower resistor to become grounded to any metal surface. This may result in internal circuitry damage.

Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.
