I am at witz end. I bought this vehicle back in August of 2020. I have replaced the rear hvac blower control resistor, both blender door actuators to control hot/cold and vent position. Ive replaced the cabin temp sensor that's located in the driver's side front pillar. I have also replaced both the front digital hvac control module on the dash, as well as the digital hvac/radio controller that sits inside the center console for the backseat to control music/ac. I cannot to this day get the rear hvac blender door to change from hot or to cold, it just blows warm, and also I cannot get the rear hvac vents to switch to the roof or floor, it's stuck on floor. I've done multiple rounds of the pull such n such fuse for X amount of time with vehicle off. And then replace fuse or fuses after X amount of time and then run the key to on position and wait X amount of time to calibrate actuators. Can some one please help me. 🙏
