Four Seasons HVAC Blend Door Actuator P/N:37534
Four Seasons 73170 blend door actuator for the 2003-2005 Cadillac CTS and other vehicles is the small motor, also called an HVAC blend door actuator, that moves the air door which blends heated and cooled air.
Clicking from behind the dash, or air that stays hot or cold whatever you set, can mean the actuator has failed. Those symptoms can also come from a loose connector or a sticking door, so with the ignition off, look at the actuator's plug for looseness or damage first; a shop can test the actuator itself.
It fits the 2003-2005 Cadillac CTS and the 2004-2005 Cadillac SRX.
