Why tailgate will not stay shut when closed on 02 avalanche?

If the tailgate on your 2002 Chevy Avalanche won't stay shut, it could be due to a malfunctioning latch or catch mechanism that isn't securing properly. There may also be issues with the tailgate cables or hinges that prevent it from closing fully. Additionally, debris or damage to the tailgate's rubber seals could interfere with a proper seal. Inspecting these components can help identify the specific issue.
