In this video, we replace the wiper motor by first removing the cover. We take out the two Phillips head screws that hold the cover in place and set them aside for reassembly. With the cover removed, the motor is fully exposed.
We then release the linkage by removing the screw that connects it to the wiper. After the linkage is disconnected, we remove the two screws that mount the motor to the machine and free the motor. To disconnect the wiring, we remove the six screws holding the thread-tree on, trace the wire to its connection, unplug it, and cut the wire tie.
Next, we place the new motor in position, reconnect the wiring securely, and make sure the connection snaps closed. We return the plug to its position, fish the wire through, and install a new wire tie. We then mount the motor with its two screws and reconnect the linkage, making sure the small bar is oriented correctly in front of the sensor so the machine can detect that the wiper has returned properly.
To finish, we check that the wiper moves freely, then reinstall the thread-tree carefully so no wires are pinched. Finally, we put the cover back on, align it with the screw holes, reinstall the two cover screws, and give the wiper one last movement check to confirm the replacement is complete.
