BMW x5 rear center seatbelt buckle is missing

SOURCE: Rear seatbelts jammed down backseats

hello tracieandmia, I am assuming that the seatbelt buckles are just underneath the seat. The rear seat bottem can be removed for access. If you reach under the front part of the seat bottem near each corner and lift up, the seat will release. You will need to give it a little yank and use a little force for it to release. Once each corner is released you can remove the seat bottem. To install the seat, slide it back under the seat back and push hard down on each front corner that you had previuosly pulled up at. You should hear a definite click/lock sound when the catches are locked.

try lifting the back seat base up (they open from the rear). Its likely to be under the seat.

SOURCE: Can't find where to connect rear center seat belt

Remove seat bottom or fish in the crack for the extra seat belt latch assembly. Normally connected to the one that is already out on that mounting point.

seat belt might be folded over in the spring loaded mechanism of the seat belt, which is preventing it from moving freely
