Rear headrest wouldn't release
Could anyone show me how to manually release the rear headrests of my 94 C280. They are stucked to the up position. I think the vacuum leak may have caused the pushbutton switch to be inactive.
Because of the vacuum leaking problem, the air has been blowing up to the windshield lately instead of to the center vents. Can the control diaphram be permernently latch up so it won't change to the defrost position?
By the way, how do I check where the leak is at? I opened the cover below my golve box, and couldn't see any visible sight of problem.
Your assistant will be greatly appreciated.
