Description

Put cabin temperature back in your control with the Dorman - HD Solutions HVAC Blend Door Actuator 604-5155. This compact electric actuator drives the blend door inside the HVAC case, positioning it to mix heated and cooled air for the temperature you select on the climate controls. It's a direct-fit replacement for the listed applications, spanning GM cars, trucks and vans plus Mack heavy-duty trucks — including the 1991 Buick Skylark, 1996-2005 Chevrolet Astro, 1994-2004 Chevrolet S10, 1995-2006 Chevrolet Tahoe, 1992-2006 GMC Yukon and 2008-2017 Mack CXU; see the Buyer's Guide tab for the full list.

Blend-door control: motor-driven actuator that moves the blend door to route air for the selected temperature setting.
Cataloged positions: listed for the MAIN, AUXILIARY and LEFT MAIN actuator positions.
Signs it may need replacing: clicking or knocking behind the dash and air that won't change temperature; if a failed blend door actuator is the cause, this replaces it.
Install note: designed to install in place of the original actuator on the listed applications.
