Dorman - OE Solutions HVAC Blend Door Actuator P/N:604-107

Reach for the Dorman blend door actuator 604-107 when a worn HVAC air door actuator stops positioning the blend door correctly. This electric actuator drives the MAIN / LEFT MAIN air door inside the HVAC case, moving it to control how air is routed and blended for the temperature and mode you select. It's a direct-fit replacement for a long list of GM cars, trucks and vans, including the 1997-2005 Buick Century, 1988-2004 Buick Regal, 1995-2000 Chevrolet Tahoe, 1997-2003 Chevrolet Malibu, 1988-2003 Pontiac Grand Prix and 1999-2004 Oldsmobile Alero — see the Buyer's Guide tab for the full list of 58 applications.

• Direct replacement: engineered to drop in and operate like the original air door actuator on the listed applications.
• Position specific: many vehicles use several HVAC door actuators, so this MAIN / LEFT MAIN unit should be checked against the part's application notes to confirm it matches the actuator you need to replace.
• Durable construction: designed and tested to strict standards to help resist wear and electrical burnout for reliable operation.
• Trustworthy quality: backed by a team of experts and engineers in the United States.

Signs a Dorman air door actuator may need replacing include clicking or knocking behind the dash, air stuck on hot or cold, or a temperature setting that won't respond — though other HVAC faults can cause these symptoms too, so diagnose the cause before replacing.
