Just bought a 2007 CLK 350 convertible. As I adjust the horizontal seat motion through the power switch the headrest moves up and down. I am clearly not pressing the headrest button at the same time. As the seat moves forward, the headrest initially goes up and then, with further inward movement goes down. The headrest button itself works fine.
Is this supposed to happen?
Short circuit?
