1. To remove the rear seat cushion, perform the following:
   1. Remove the bolts holding the cushion to the floor.
   2. Push the center occupant seat belts through the openings in the cushion.
   3. Remove the cushion from the vehicle.
2. Remove the seat back by performing the following:
   1. Hinge the seat back forward and disengage the push-in fasteners holding the carpet backing to the trunk floor.
   2. Remove the bolts holding the outboard hinge pivot bracket to the seat back.
   3. Pull the seat back outward to disengage the inboard pivot and remove it from the vehicle.

You have a broken wire in the seat. The blue wire inside the seat cushion will break or burn in two. If you are handy with tools you can remove the seat, remove the screws from the control switches cut the hog nose ring clips, undo the velcro on the back of the seat bottom and carefully remove the bottom seat cover. You will find that the blue heating element blue wire in burned in two. Cut the bad part out, slide some heat shrink tape over one end. Slide it far enough so that you wont shrink it from the solder gun. Solder the two wires together and keep the joint minimal so that the shrink tape will slide over the solder joint. shrink the tape with a heat gun or hair dryer.Put everything back in reverse order. You will need to go to an older conventional auto parts store and buy a hog nose ring kit with the pliars to replace the upholstery. Go to an upholstery shop and they can tell you where to buy it . It should cost 3 or 4 dollars. this whole seat repair should not cost over $8.00. Also remember check the fuses first and also remember that the seatbelt has to be fastened for the seat heater to work.

some cars yes..some no. I would go buy some 3M spray adhesive and glue it back. Unless you are really concerned about the looks. Then you would need to buy a new headliner and replace the old one. That can mean removing all door trim around the every entry, removing the rear deck lid, removing the rear seat back, removing anything that touches the headliner.

there are usually 2 little buttons, 1 on each side, underneath the seat in the front. push and pull up

Remove the seat cushion retaining bolts, detach the seat cushion and remove it up and out from the vehicle.

Remove the rear seat back retaining bolts at the bottom of the seat back. Pull up then out to disengage the upper frame from the hangers and remove seat back from the vehicle.

Installation is the reverse of removal.

I searched the owner's manual and there was no mention of folding the rear seats down. If you don't have a manual, you can get one here: http://www.extendedgmwarranty.com/owners-manual/buick/1999-Buick-Century.pdf

Hi Xit.....The factory XM module is in fact located under the rear shelf trim panel. You will have to remove the rear seat cushion, just pull up on the front of the cushion about 12 inches in from left and right corners. Remove the cushion from the car. Open the trunk and remove nuts located on the seat back just under rear shelf metal. Back inside the rear seat area, remove the seat belt buckle bolts located inboard of right and left lower corners of the seat back. Remove the seat back. You will now be able to see the (2) plastic fir tree pins that hold the shelf panel trim in place. Remove the pins.
Now comes the hard part, remove the right and left quarter sail interior trim panels ( Caution: roof rail air bag located behind right and left panels) the fasteners are located behind the "SIR" plastic buttons in the sail panel trim.
All in all, unless you have the proper tools and take the proper precautions, you might want to take your Cadillac to your local dealer.
Buy the way, is there something wrong with your factory XM module?
Let me know, regards.
