Coccyx cushion due 14/21 February has not yet arrived

Look on the bottom of the lower cushion, where it meets the floor. If you don't see 2 screws or bolts (one on each side of cushion) there, then there are clips that the bottom cushion uses to fit tight into the floor. To remove the bottom cushion, you shove it towards the rear and then lift up and out of where the clips hold it fast. Sometimes you really have to push the cushion hard towards the rear to get the clips loose. Then you lift up the bottom cushion and remove it. Now you can remove the upper portion of the seat. Usually there are 2 bolts down at the bottom of the upper cushion. Remove those and the upper portion can be removed. If there are no bolts on the bottom of the upper cushion, then you just lift it up and out of slots that held it fast.
Do the bottom cushion first.

On what? 3 possible ways the rear seat cushion is removed. On some the seat has clips that lift straight up. Or some have 2 small bolts at front bottom of rear cushion. Remove the bolts and seat slides out easily. The final way is old style: a heavy wire on bottom of cushion, one on each side, fits into slots that come up from the frame underneath. To remove, push cushion hard to the rear until the heavy wires can be removed (lifted up) from the slots. Do one side at a time. These are the most difficult to remove the rear bottom cushion. You have to push hard against the cushion near the bottom of it, pushing it backwards, so the wire comes out of the slot, and then cushion can be removed.

First try lifting straight up on the cushion. Since there is an access panel to the gas tank, it is very possible the cushion is easily removed by lifting straight up.

At least 3 ways the bottom cushions are held in place: some have bolts at the bottom of the cushion, one on each side-when bolts are removed, bottom cushion pulls out. Some have plastic clips on the bottom of the cushion, pressed straight down and into holes in the frame. To remove pull up on the bottom cushion. The other way of holding is a metal bar or rod (about 2 inches long) that is on the bottom of the cushion, close to the front of cushion. This bar fits into a metal clip that juts up from the frame. To remove this kind, you have to push hard on the front of the cushion, so the bar or rod lifts out of the clip. The rod only has to move backward about an inch and it will lift out of the clip. There are only two clips- each is about 1 foot from the ends of the cushion. These types of holds are the most difficult to get to move. Sometimes you need to put your knee against the bottom cushion and give it a hard shove backward. You will know when you have one side loose. That side can then be lifted up a bit. Then do the other side.

First check for 2 bolts at the bottom of the back seat cushion. When you have the bottom seat out, you can remove the top cushion (the backrest) out if you want to. The backrest usually has two bolts at the bottom. Remove them, and lift up the backrest and out. If no bolts at the bottom, just grab the cushion and lift up and then away.

Reach down in the bite-line (where the seat cushion and the seat back meet). Pull up on the seat cushion until the cushion raises above the bottom of the seat back. Pull the seat cushion towards the front. There are two metal tabs that are hooked into the front of the seat cushion that holds it in place; unhook these by moving the cushion forward. To replace, reverse the procedure, but make sure the seatbelt recepticles are exposed before pushing the seat cushion down into the bite-line.

Its on passenger side under rear seat cushion. Get in back seat FACING rear seatback, grab under lip of bottom seat cushion, and pull straight up. Disconnect seat heater connector (if so equipped) on passenger side and remove seat bottom. Tada! There ya go! Oh... btw. Its a $150 battery due to the venting system designed into it to vent fumes through a tube to the outside world. Thanks Cadillac!!! :(

We have seen related problems in South Africa. It relates to a poor earth whereby the seat frame becomes the heater-scary! My advice is to seek legal advice, you may make enough money to buy a Mercedes. Then the seat will work well but not much else!
