My tailgate on my isuzu rodeo will no longer open. I tried switching my box around so my subs face right against the tailgate and now it will not open. I think the rattling/vibration broke something in there. Anyone have any tips or ideas on how to fix this without going to the dealer and spending $? I have tried taking the panel off but it sort of overlaps with the floor of the car and the only way to get it off is if the tailgate is open laying down. Also I can't move my box without the tailgate open so it makes it kind of hard. Thanks.
