Air Conditioner problems of the 2011 Dodge Avenger

Problem with the air conditioning system where the passenger side of the car will blow cold air and the drivers side will blow warm air despite this being a single zone a/c system. This issue started after heavy acceleration getting on the highway when I saw smoke billow from the center a/c vents. I pulled the car over and looked under the hood, but found nothing burning. It was later that day when I noticed the issue of the passenger side cooling and the drivers side not. After much reading, this is a wide spread issue affecting multiple model years.

Takata recall heat in the car is not working. Passenger side doesnt work at all. The drivers side works at times but not really. I got air conditioner fixed and supposedly heat was fixed same time from Dodge dealership in toms river it was not.

During 2013 my car would give me problems starting in cold weather. To remedy this I would turn on the lights before turning on the vehicle. It worked. I brought it to the dealership while I had warranty for a check up and they told they spotted no problem codes and the car was fine. September 15 2014 it began to get chilly again. As I was driving, going uphill, the lightning bolt came back on and my car dropped to 20 mph immediately. I referred to the car manual and found this is called a etc issue, electronic throttle control. I've brought this attention to dealership while my warranty was still on the car, and even tho I stated the issue was there, it wasn't attended to because no problem codes came up. My local mechanic ran a diagnostic test and still no codes come up. Aside from this, there is a heavy knocking noise when my air conditioner is turned on for some time. Idk what this issue is but again I had brought it up while I was under warranty and nothing was done.
