I have an interesting scenario. My blend door actuates but is backwards. When I have the dial set to cold the blend door moves to heat position and similarly when the dial is set to heat the door moves to cold... So I removed the glove box to make sure the blend door is moving and it is however I can confirm in the opposite direction s. So I thought again it was the sensor being broken. I got two other low range switches from the junkyard to test but same thing. Tried a different dial control too and again same. I have even replaced the N19 module as well thinking it was faulty but got the same result. Hot is Cold and Cold is hot. I'm just glad the blend door motor works but need to figure out this orientation situation. I have read through tons of posts about broken actuators but never backwards ones. any insight is helpful!
