the rear winshield wiper does`t work

is the wiper motor getting power when turned on? Fuses been tested?

I had the same problem. take the rear gate panel off carefully. i lubricated the gears and took a small hammer or a screwdriver handle and tapped the motor and gears. i than inserted the keys into the ignition and turned to on position did not start the car i than held the up rear window button (left side by the door) until you hear a click. this resets the window and wipers. just so you know, i tried this several times now they work. i hope this works for you
