Four Seasons 73181 mode door actuator for the 2005-2007 Cadillac STS drives the HVAC mode door that sends air to the vents you pick on the climate controls.

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

If air comes out of the wrong vents, the mode setting won't change, or you hear clicking behind the dash, the actuator can be worn. Those signs alone don't prove it is the problem, since a fault in the control panel can look the same.

This is a direct-fit replacement for the 2005-2007 Cadillac STS.
