On my granddaughter's 2003 - I ran driver's side, electrical seat back, drove the car up the driveway, and parked it. About a week later I tried to start the car but battery was dead. A brand-new, 3-year battery was put in this car in January, 2010 and my granddaughter drove this car to WY (from IN) and back returning just less than a week before this (moving seat) happened so battery should have been fully charged. When I tried to jumper her battery, I got very large spark when making last connection. Tried again with very large spark. We took battery out and got a new one. When new battery connected, I got normal small spark. Car started fine but neither driver's nor passenger electrical seat works although I think the seat heaters work. My son-in-law replaced the circuit breaker for the seats but no help. After a day or so, granddaughter discovered the interior lights no longer go on but she doesn't know at what point in this sequence this happened. Finally, several days later, she discovered her taillights don't work either although brake lights work. These are only things known to not work at this time.

I think you have a short in the seat motor. Doublecheck circuit breaker for electric seats. It has a reset button on it. Perhaps it has tripped. If yes, need to find short in seat.

Your car is 18 years old. It's likely history. Sell it as is for what you can get.

Buick Lesabre Heated Seats not working

The problem is most likely caused by shorted heating grids in the seat cushion itself, kind of like the heating element in an electric blanket, very expensive to replace.
