w208 clk front seat fore/aft motor how to
The seat motors start to tell you they are going bad by blowing fuses in the trunk.
When you check the fuses and find they are all OK and the seat makes clicking noises but won't move ,
WELL THEN YOU GOT YOURSELF A DEAD MOTOR!
I came up with a fast way to replace the motor WITHOUT removing the entire seat.
Sometimes your seat will be in a position where you can't get to the bolts to remove it, so this way works
Take a T27 wrench as pictured and remove the right front & left front seat bottom bolts from
the seat bottom as pictured. You don't have to remove anything to get to them. You might adjust
the seat lift and rise to get a good angle.
Once both bolts are off then seat lifts up giving good access to the area.
Disconnect the 4 plugs from the front of the metal bracket which holds the plastic black box
which all the wires go to. Remove the small nut on the front right corner and the T25 bolt
on the left side. You can now have farily free access to the fore/aft motor.
IT IS THE CENTER MOTOR which moves fore/aft. Clip all the zip ties on the center motor leading
to the controller so you will be able to unplug it from the bottom.
Use the T25 handled driver from the picture to remove the motor top bolt & then remove the bottom
bolt using the same tool. The motor is now out.
The small shaft remains behind so carefully slide the new motor in place. Put in the top bolt
& then the bottom bolt. Connect your wire into the scoket from which you unplugged
the dead one from.Hint the plug orientation has the colored wires the same as the adjoining plug.
Replace the nut from the silver controller bracket and the T25 bolt and your controller is back in.
Reconnect the 4 plugs running along the front of the silver bracket.
Now replace the two T27 bolts from the left & right seat front edges to the cushion.
That's it about 35 mins.
