How do you replace a rear seatbelt in a vauxhall meriva?

To replace a rear seatbelt in a Vauxhall Meriva, first, remove the rear seat and any necessary trim panels to access the seatbelt mounting points. Disconnect the old seatbelt by unbolting it from the chassis and the retractor mechanism. Install the new seatbelt by securing it to the same mounting points, ensuring it's properly anchored. Finally, reassemble the seat and trim, and test the seatbelt for proper operation.
