Has anyone who owns an 2002 c240 had any problems with their defoster sticking open at all times with the heat on? And if so how did you correct this problem? when you switch the control for the floor and vents etc... it works fine but the defroster overrides the a/c with the heat.when turning the fan speed up it also comes out more out on the defroster as well and less out the the vents. Any input would be great Thanx

I'm not sure I completely understand the issue. When you select defrost, regardless of the setting on the climate control, it will turn on full heat and direct it to the windshield. Even if the A/C is on when the defroster is selected, you will get heat.

Now if you are can't turn the heat off without defrost selected, then there is an issue.
