A worn HVAC blend door actuator can show up as clicking behind the dash, air that stays hot or cold whatever the setting, or air that comes out of the wrong vents. Before you replace it, rule out a blown fuse, a damaged connector or a jammed door or linkage, since any of those can leave the temperature stuck too. If the actuator is the cause, this one replaces it.
It is a direct-fit replacement for the 2008-2015 Cadillac CTS and the 2005-2011 Cadillac STS.
