posted 3 times ,
the 523330 code is for the blend door actuator.
HVAC ,means heating ventilation and air conditioning
system.
in driver parlance means AC cooling or heating to the cab.
the huge box under the dash has dampers insides one is called.
blend. (it blends hot and cold air to what you want)
it is stuck, and many times just the actuator motor to it is bad
sorry no huge truck manuals here, so cant guess.
but most modern are use electric motor drive damper actuators.
it has nothing to do with engine, if it gets fully hot and hot air from the dash is good, no country told.
