Dorman - OE Solutions HVAC Blend Door Actuator P/N:604-136
Take command of your cabin temperature with the Dorman - OE Solutions HVAC Blend Door Actuator 604-118, a direct-fit replacement for the 2000-2005 Buick LeSabre and 2000-2005 Pontiac Bonneville (see the Buyer's Guide tab for engine-level fitment). This is the MAIN air door actuator — the small electric motor that positions the HVAC blend door to direct and mix airflow through the heating and cooling system. If a failed actuator is the cause of inconsistent temperature, clicking or knocking noises behind the dash, or air that won't switch between hot and cold, this replaces the original unit.
