I'm having a problem with the pasenger power seat on my 96 sc400, the motor works, but the seat seems to be stuck on somthing, but its not. One side will move a few inches back and forth, while the other remains still, any ideas. I have looked under the seat with a mirror and flah light, and observed the motors, and worm drive gears, it apears that one of the worm gears is not rotating. There apears to be an enclosed drive shaft runing from the motor, to the oposite side, but because its enclosed, I can't see whats happening. My next question is, how do you remove the seat, it dose not appear to a strieght forward task.
