Motor, Wiper: Removal: Front
On vehicles equipped with the high voltage system, disconnecting the 12-volt battery negative cable alone will not power down the 12-volt system. You must perform the 12-volt Power Down procedure before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
Do not apply pressure to, or pry on the plastic drive link bushings. When removing a drive link from, or installing a drive link onto the ball stud on the wiper motor crank arm apply pressure to, or pry on only the metal portions of the drive link around the bushing. If the bushing is damaged, the entire wiper linkage module MUST be replaced.
Do not remove the crank arm nut from the wiper motor output shaft. The crank arm is indexed to the output shaft with the motor in the park position during the manufacturing process, but there are no provisions made for correctly indexing this connection in the field. If the crank arm to output shaft indexing is incorrect, the entire wiper motor and crank arm unit MUST be replaced.
