[W126 Coupe] Seat Lock problem

[Michael Ramay]

Prior to removing the seat from the car, check the lock itself in the seat
back - it's easier that moving that heavy, heavy seat. Move the seat forward
a bit, lean the seat back forward and take out the two chrome philip head
screws on the bottom of the the plastic panel that is the back of the seat.
With that panel off, you can see the seat lock and the vacuum line that
locks the seat. It's now easy to test the vacuum line with a Mity-Vac to see
if it's still connected. It took longer to type this than it should take to
do this!!
