2. Remove the wiper arm from the outside of the trunk lid. Remove the union nuts, washers, and arm nut from the wiper arm.
3. Disconnect the wires from the wiper motor.
4. Remove the mounting bolts and the motor itself.
5. Reassemble in reverse order. Make sure the motor connections are secure. Tighten the mounting bolts to 10 Nm. When installing the wiper arm, leave a gap of 25 mm between the glass and the blade. If the wiper is too far off position - either too high or too low - they will slap too hard when working on wet glass.
