Hi all, this is my first post
Strange thing I noticed every time I drive my mb on highways, after exactly 2 hours of driving blowing air from the central vent will stop and start blowing from the top vents (near to the windshield) .
The little blue button is on and no matter changes I do on the climate control (up, down, front) it will stay blowing from the top and the side vents only. This issue goes away after stopping the engine for a while.
What could be the issue here?!!
