1. Locate the middle rear seat belt assembly. It is usually located on the B-pillar, which is the structural support between the front and rear doors.
2. Remove the plastic cover of the seat belt assembly by prying it open with a flat-head screwdriver or other suitable tool.
3. Unbolt the seat belt assembly from the B-pillar using a suitable ratchet or wrench.
4. Unbolt the seat belt retractor from the floor of the vehicle.
5. Remove the old seat belt assembly from the vehicle.
6. Install the new seat belt assembly in the reverse order of removal.
7. Test the seat belt to ensure that it is functioning properly.
8. If you are unfamiliar with vehicle repair tasks like these, I would recommend seeking assistance from a certified mechanic, for safety reasons.
