Cooling Fan Relay: Notes

WARNING: This page is about a different car, the 2002 Oldsmobile Bravada, 2002 GMC Envoy XL, 2002 GMC Envoy, and 2002 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Installation of the proper relay is critical. If an enhanced relay (equipped with a diode) is installed into a position requiring a standard relay (not equipped with a diode), excessive current will damage any components associated with the relay or its associated circuits.
NOTE: Tools Required: Relay Puller Pliers (J-43244).
