My 1994 E320 cabriolet sometimes has no lights on with the motorized rear headrest, but sometimes the red warning light is lit and the switch is blinking. The switch stops blinking when i lift the head rests, but the red warning light wont go off.

Not all the time, but most of the time this behaviour occurs. The roof works normally, i've checked that the rear subframe sensors are clicking and they seem to be in the right position (not clicked when car is sitting down, and when lifted up, the suspension parts makes the sensors click).

I've tried the reset thing, but it doens't seem to do anything. Everything works, but should i be worried?
