Dorman - OE Solutions HVAC Blend Door Actuator P/N:604-821
Dial in the cabin temperature you set with the Dorman - OE Solutions HVAC Blend Door Actuator 604-881. This small electric motor moves the blend door that mixes heated and cooled air inside the HVAC case, and it drops in as a direct-fit replacement for the 2003-2007 Honda Accord (see the Buyer's Guide tab for engine-level applications). It replaces the MAIN air door actuator position — because these vehicles often use several actuators for different HVAC doors, review this part's application notes to confirm it matches the position and function of the one you're replacing.
Signs this actuator may need replacing include a clicking or knocking noise behind the dash, temperature that won't change from hot to cold, or air that stays stuck on one setting.
