During the winter months, there was no heat coming from the driver side air vents, now is summer I am having the same issues no cold air on the driver side air vents.
all other vent work great during the winter or summer .
2015 Chrysler 200 limited with dual climate control.
Any idea what could be the the issue, and would it be an easy fix I can do myself.
thank you in advance

 

While I'm not familiar with your specific model, there are some general things that should apply. First, don't overlook the obvious. Make sure that the vents are open. Dash vents all have a way to be closed right at the vent. Make sure yours are not closed. If the problem isn't there, it's probably a door within the plenum chamber. The two sides of the system are controlled separately by a computer (usually the body computer or a climate control module) that opens and closes various doors within the plenum to control temperature and where the air is directed (toward the floor, dash vents or defroster). There are also doors to control where the air comes from (outside or inside). The doors are controlled by the computer depending on the settings you have chosen and the conditions existing. The computer controls the doors by means of small motors that actually move the doors. If a door is not working properly, the problem could be the control head (where you choose the setting you want) the connection from the control head to the computer, the computer itself, the connections to the door motor, the door motor or even the door itself.
So the solution to your problem might be very simple or very complicated. The repair, depending on where and what the actual problem is, could involve removal of the entire dashboard to get to a small part deep inside the system.

 

Thank you for your help. The Vents on the dash board, were closed and it didn't release , it has been close since last fall.
All winter I drove with less heat in the car and didn't figure it out.

 

For the most part, heat should be coming out the floor vents, not the dash vents. Since heat naturally rises, you want the heat to be injected into the car down low so it can rise and distribute itself through the car. You probably wouldn't have gotten much more heat in the car with those vents open. Hot air blowing on you face would be uncomfortable anyway. That's another reason the automatic climate control will direct heat to the floor.

Cooling, on the other hand, will generally be directed out the dash vents by the system. Again, since cool air naturally sinks, it should be directed out the dash vents to cool from above and distribute the cooler air more evenly. When you get in a hot car, you want to feel the cooler air on your face to feel comfortable more quickly. You will definitely feel the system be more effective with those vents open.

There is a great deal of effort put into the design of an automatic climate control system for a car. I know, as I participated in the design and development of early automatic systems many years ago. The best way to operate such a system is to "set it and forget it". Dial a comfortable temperature and press the "auto" button and just let it do its thing. You might want to dial up a couple of degrees in the winter and down a few degrees in the summer, but avoid dialing big swings. Some people think they can operate the system better by cranking the temperature up to 90º when they get into a cold car in winter, then they get hot sitting there in their winter coats so they either open a window or crank the temperature way down. If you tried to heat up an oven by turning it up to 500º to bake a cake, and then either opened the oven door to let out the heat or turned it off to cool it down, you'd wind up with a mess of a cake at the end. "Set it and forget" it works best.

Glad to be able to help.
