Sensor ? you can search on here and see that it's usually replacing the entire HVAC distribution box as in 2019 they warp , I'd make sure that is what the dealer does.I went to turn on the a/c , and heat comes out of the drivers side and a/c out of the passenger side , had an appointment for a oil change so I had them look at it , they say it’s a sensor and it’s a 20 hour job to pull the dash apart to get to the sensor
