Is your seat locked in the full slide forward or rearward position?

If so, the pink plastic washers at either end of the worm gears movement have broken due to wear over time. The pink washers stop the seat from overtravelling and going off the worm gear, once the washer breaks off and fall on the carpet, the next time you use your electric chair, the mechanism will over travel and get lodged at the end of the worm gear thread tightening it like you would a cap to a coke bottle.

Once you flick the switch to move the chair direction no movement = short = fried wires may kill the motor.

I rebuilt my drivers chair and have yet to find how to source these pink washers. My lodged worm gear is the one for knee height so I don't care too much.
