A failing HVAC blend door actuator can show up as clicking or tapping behind the dash, air that stays hot or cold when you change the setting, or air from the wrong vents. A jammed door, damaged linkage, a wiring or connector fault, or a blown fuse can be behind these signs too, so find the cause before you buy.
The vehicles it fits include the 2006-2010 Hummer H3, the 2007-2010 Saturn Sky and the 2009-2010 Hummer H3T. If yours isn't one of those, open the Buyer's Guide tab and look up your exact model and engine.
