300E Rear Head Rests Stuck up
 

My 1987 300E has rear head rests stuck in the up position, nothing happens when I press the dash switch and the fuse is OK, can anyone let me know how to manually lower these, or how to add power to the rear to jump the switch to lower, thanks in advance

Lift up the bottom seat cushion (two red tabs) and locate the valve that controls the rear headrests - it's on the driver's side. Bypass the valve, connect the lines together, and start the engine - the headrests should retract.

Perfect ! thanks, completed exactly as described
