Four Seasons 73175 mode door actuator for the 2003-2005 Cadillac CTS and other vehicles is the small motor that moves the HVAC air door, sending airflow to the vents you pick.

  • Backed by over 50 years of mobile A/C experience at Four Seasons
  • Meets or exceeds OE specifications for fit and function
  • Quality internal motor, drive gears, electronics and connections
  • Tested for function, durability and longevity

Air coming out of the wrong vents, vents that will not change with the mode setting, or a clicking behind the dash can mean the actuator is not moving its door. Before you replace the mode door actuator, rule out a blown fuse, a damaged connector and a jammed door, because each of those can also leave the air stuck at one outlet.

The same part is a direct-fit replacement for the 2004-2005 Cadillac SRX.
