You will most likely need to replace the seatbelt retractor. The best place to find a replacement is usually your local self service auto salvage lot. I replaced mine last year and it ran me $10 for the retractor and u pull and pay.

Under the rear seat. Fold it forward and you will also have to pull up the carpet and cover under the seat.

I am going to assume you mean the normal rear seats, not rear facing seats in the very back.
The rear seat folds down. The benches fold up from the back. When they are up you can see how to easily remove them if you want.
When the benches are up the backs fold down. There are levers on the top the slide forward to release them so they can be folded down. Tip the outboard head restraints forward by pulling their straps. The center head restraint has a button behind its right-hand support that you push to allow it to be lowered.

MIGHT HAVE TO REMOVE THE SEAT BELT TO HELP RELEASE THE TENSION AND RECONNECT IT BACK.

They have a problem with the seatbelt retractor getting jammed up causing the belt to jam & not let the rear seat fold back up.The easiest way to get the seat back up is to cut the seatbelt & fold up the seat.Then the rear seat needs to be disassembled to gain access to the seatbelt retractor assy which has the seat belt made on.Hopefully it's still under warranty or Ext. warranty.hope this helps

you can remove the bolt that holds the seatbelt to the floor by pulling off the seatpad where the belt goes to the floor and then raise the seat and the belt should reset. this happens on my passenger side rear seat.

To fix that scenario, I have to get to the bolts anchoring the seat belt which can be found under the rear seat. Which a socket wrench, remove the bolt freeing the seatbelt to allow you room to release the lock to pull the belt out from the top of the back seat. You may now push the back seat into its upright position and then refasten the seatbelts with the bolt to it's former position under the back seat.

When I in later times need to lower the back seat, I will either loop the seatbelt around the head rest or tie two belts together allowing for slack in case the belt tightens again when trying to move the seat back to its original position.

.....Very frustrating!!!
