2022 367 logging truck with 57000 miles.
The heat adjustment control quit a month ago.
13 months from the in service date.
I changed the actuator that moves the airbox door and nothing.
Also tried swapping the fan speed, door position and temperature control module under the radio and still nothing.
I have the heat door on the airbox moved to full heat with a set of pliers
pete 367 no heat adjustment
