Hi everyone. This is my first post but I have enjoyed the knowledge from reading everyone's discussions. The front and back of my power seat does not move up or down anymore. I pulled the seat up and when I push the button up or down the motor works. I did a search of this forum and tried turning the screw by hand and then it works for one revolution then stops again. I opened the differential where the screw connects to the post coming out of the motor and found the white gears have broken teeth in one spot. I have tried searching the internet but can only find these gears for Infiniti's and Nissans. Does anyone know where I can find these gears or have another solution?
