I have replaced the relays for both the front and the rear wipers, and the motor in the back door for the rear wiper. Can hear the motor when I turn on the wipers, but the wiper itself doesn't move.
Don't make this more difficult than it is. One of the gears inside the wiper motor is made out of bad quality plastic, and wont last very long. Replace it with a used one is just a wast of money, get a brand new one.
THEN THERE IS BUT ONE EXPLANATION, THE WIPER TRANS IS NOT CONNECTED TO THE MOTOR DRIVE HEAD.
SOURCE: the rear wiper workes if
Hi You may want to check one thing. Roll the rear window down a few inches and then rolll it back up. There must be a relay switch to tell the car the window is open. If that does not work, it might be the relay switch. There are three possible points of failure; the motor, the parking switch, and finally the switch that turns it on. Please get back to us if you have further query else please accept the suggestion.
Obviously, the motor is located in the hatch itself but also there will be a parking switch that supplies power to the motor after the user switch is turned off and until the blade is in the park position. The user switch is of course located on the dash or in a stalk on the steering column. Check for voltage with a multimeter at the motor and/or continuity of it. You should be able to eliminate the items that are working in 20 or 30 minutes.
