If the lock moves erratically up and down when pressing the remote control button to open or close the car, there is a problem with the lock that can be repaired without replacing the entire lock, but you need to remove the door panel. Once the lock is disassembled, remove the plastic cover by unscrewing the screws and opening the side tabs, disconnect the cable and the safety catch: inside the lock, you will find a broken plastic gear and springs that have come loose; insert the new gear after applying grease and reattach the springs, then reconnect the cable, the safety catch, and refit the plastic cover.

How to Remove the Rear Seat of a Hyundai Tucson?

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat.
