AnswerSlide bottom of bench seat back and upward to release clips (requires a lot of force)Lift bench seat outYou will see bolts or clips holding the back of seat release/unbolt these and push stright up to release upper clips on back of seat to remove. 1999 Deville has two additonal bolts in the trunk that release the top of the seatback.
On a 79/80 Deville there are nuts under the seat that have to be loosened and be careful of the power seat wires and mechanisms under the Seat.
how do i remove the seat
Just pull the seat up to remove safety latch and it will come out
pull up on the front part of the seat
under the back seat
Use an axe
I have a 2000 Deville DTS. The battery is located below the back seat. Just pull up the seat (not back), and you will find the battery.
its under the back seat....
grab the front lower edge of the seat and JERK HARD back and up
Should be bolts in each corner of seat
Using the seat back tilt lever lower the seat back as far as it will go. Sit in the back seat. Place your arm around the head rest and pull hard. The headrest can only be removed in this position. Works for driver and passenger front seats.
