Weird happenings
I have a 2002 C240 and have some questions about how the heating system works. I have the standard climate control system with a fan dial on the left hand side and an air flow direction dial on the right. I can't figure out how to set the right hand dial nor can a figure out how to keep the my calfs (my legs not baby cows) from feeling cold.
I understand that the upward arrow is to have the air flow from the upper vents, and the downward arrow is to have the air flow to the floor. Logically, the up and down arrow has the air flowing from both the upper vents and the floor vents. What does the setting represented by the two rectangles do?
Also, do any of you have any idea why if I have the air flow set at the up and down arrows, the backs of my legs would be cold while I'm driving? It almost seems like there is cold air coming from under the seat.
Thanks,
Dick

I understand that my question, might, to you, sound nieve, but to me, I was a valid and necessary question. I did RTFM and didn't get the answer that I needed. What the manual appears to say is that the air direction dial only works when the system is not on automatic, and that the temparature should be set at 72 degrees and remain there. Now perhaps I mis-read the manual or remembered something incorrectly that I read a while ago. Regardless, I chose to ask other C-Class owners in the belief that this would eliminate the confusion. Oh, by the way, I did bring the car to the dealer yesterday to have them check on the cold at the back of my legs. They couldn't give me any answers.
Thank you for your most helpful answer!

I'm bored at work today so I'll help you out.
Do you see the blue dial between the 2 center dash mounted air vent? roll that down so no cold air will come out. Make sure that both temp dials are set to max heat, 80F I believe. Pointing the right vent selector knob to the "2 squares" position will make warm or cold air come out every vent in the car.
Hope that helps

Best thing is to close the windows, stop the car, and just play around with it. I mean the HVAC system, of course. There are children present! :p

One thing I'm a little bugged about is the lack of forced air in the car as you are driving at freeway speeds. In manual mode, I have to turn the fan above 3 in order to get any airflow going. Other cars I've owned have had such good forced air flowing in - you didn't really need a fan as long as the car was moving. But perhaps this was a design decision (forced air is hard to turn off).
And I also note the car tends to fog up inside quicker than most when you run in EC (Economy) mode.

Opening a window will force some air in!

I get in cars sometimes when people have them turned off and start driving before I notice it. On really hot days, I can only take it for maybe 10 seconds. You start roasting immediately and it's hard to breath. That's when you notice there is no forced air.

Just had a thought, can you imagine if cars were like office buildings
where you can't open a window. That would be scary. ![Big Grin](https://mbworld.org/forums/images/smilies/biggrin.gif)
