VERY COMMON symptom for 200/Avengers...plugging up HEATER CORE. Do you have the 2.4 or 3.6 motor? Not that it matters much they are all known for this problem.

 

 

Plugged heater core. Mine is having similar issues, also doesn't want to direct the airflow properly either.

They're talking about a recalibration for this as a fix, perhaps, but come on.

Recalibration? Its a god damn blend door, it directs air flow.

So fed up with anything made in the last 10 to 15 years. More technology and more greed equals less TLC when the manufacturing and engineering process is happening.

 

Sorry...Not sure of what way you are going with your response, are you agreeing about heater core or saying a blend door?
As long as position outlets are working and you get proper heat out the left(drivers side) then it can only be the core, and that is due to the way it is mounted inside the HVAC box inside the dash. Heck of a big job to do, I did a core on our 04 Neon and that was bad enough! I found a way to cut the HVAC box open to remove it's core(and seal it back up) without having to have the A/C system evacuated and then recharged after. But still had to take the whole dash and steering column out to get to the HVAC box! I would DRED doing one on a 200/Avenger!
