A door check links the door to the body and limits how far the door can swing open, helping it stop and hold at its open positions instead of swinging freely. Signs this part may need replacing include a front left door that opens too far, will not stay open, or pops and clunks as it moves. Inspect the door and hinges to confirm the cause before replacing. For the complete list of fitting vehicles, see the "Vehicles it fits" section.
