96 IMPALA FRNT PASS SEAT

did you check the fuses on the left side of the dash as you enter the drivers door. Also, what stopped working? the whole thing? as in all 9 ways? or just one of the switches? does it move forward and back, just doesnt tilt anymore?

I would pull the door apart and with a multi meter make sure i am getting power to the door, then pull the plugs off the motors under the seat and make sure your getting power to the motors when you activate the switches.
