In the following 2 pages we will illustrate how to replace the windshield wiper motor on a 2000 Mercedes Benz C230 Sport, take note that these steps will be similar for most Mercedes Benz C-class vehicles built from 1994 to 2000.

 Lift the wiper plastic cover and gently pull it out, set it aside on a workbench.

 Using an allen wrench remove the bolt that holds the wiper arm to the shaft, remove the wiper arm.

 Remove the left and right plenum covers by pressing the plastic tabs shown in the image and pulling them out at the same time.

 Remove the engine compartment lip seal.

 Remove the two outer nuts that hold the corners of the plenum air duct down.

 Remove all the plenum air duct phillips screws.

Remove the plastic cover located beneath the wiper mechanism.

 Detach all the plastic hooks and lift the plenum air duct up and remove it from the vehicle

In this particular vehicle we opted to remove the cover from the wiper motor to inspect the gears, we suspected that it had a stripped gear because the wiper would stop half way and it would make a grinding noise.

 As you can see in the image, we were right, the plastic gear was stripped, we were unable to buy the gear by itself so we had no choice but to replace the complete wiper motor.

 To be able to disconnect the wiper motor it is necessary to remove the relay box cover, start by removing the fuse box cover as shown in the image.

 Next, remove the relay box retaining screws and remove the plastic cover, set it aside.
