Vacuum windshield wiper motor
How do you remove the vacuum wiper motor on an l110? I noticed there were two screws that mount it to a bar that is attached to the bars that move the individual wiper arms but on the back of the screws there is something flat that turns with the screw and won't allow it to be removed. I want to take the motor out so I can take it apart to clean it and lube it. Any help)
