Heating and AC Temperature and Air Delivery Mode Do

On a vehicle 11 years old, I would say
put gauges on it & then leak test it.
Most likely has a leak & is low on refrigerant
& when you move ,you put too many BTU's across
the evaporator from the cabin & it is not at 40 degress
to remove the heat

sounds link the servo door has either broke off or is not working and it is stuck in a closed position

one of the doors on the heater vent could be stuck shut possibly

Hi, check the air vent doors make sure they are not broken and the door motor is working, they have a bad problem about breaking . if i can help just re post .
Thanks dodge tec

CHECK FOR LOW COOLANT LEVEL IN THE RADIATOR.LOW COOLANT LEVEL WILL CAUSE POOR HEATING PROBLEMS.

the heater blowing cold at an Idle and warm while driving it,is usually low coolant in the radiator,remove the radiator cap when engine is cold,fill to the top,and fill overflow tank to full,if that doesn't take care of it,check the heater hoses at an idle and see if they are both the same temp,it might be a water pump not doing its job.

on the bottom of the heater case is a vaccum door right on top of the hump it has a white plastic adaptor that breaks replace with dealer part it just pops off

Sounds like an ink pen or some other object may have fallen into you duct work causing a door to be jambed or possible broken.

I have a 1996 Dodge Ram 1500 club cab. I have had my a/c recharged but it is only blowing barely cold air. It used to shut down when I accelerated and blow hot air before. I don't have that problem anymore except barely cold air. Any solutions?
