Hello all. I can’t seem to find much info on my 2021 Dodge Ram 3500 (Dually). I need to know how to remove the dash and replace the blend door actuator for the driver side. Passenger side heat is good. Cold air is good on both sides. No heat is the issue. Floor no heat either. Any help is greatly appreciated. Ps. I removed the glove box to see if there was an actuator but none is visible.
