i have a 2000 bonneville and every time i open the trunk water starts pouring out of the top of the trunk. what is the cause of this? iv been looking at alot of forums trying to find an answer and the closest thing iv found is a third brake light leak. is that the problem?

I know we have members that have had the same issue i do not off the top of my head remember what the cause is but im sure somebody will be along to help you out

ok i hope so i want to put subs in but not with a leaky trunk

Yeah i understand my buddy steve found rust in his and got his stuff wet lol...Le me get aholdo f somebody for you to see if they can better help i Just cant remember what causes it and what the fix is

here are things to check in your trunk. (i've had most of these)

4 bolts under trunk latch that hold the rear bumper on. silicone them

trunk seal gasket black rubber thing around perimeter of trunk opening, coat with vasoline close trunk open trunk look for areas where the vasoline is not on the deck lid. replace gasket if needed.

tail light bolts. make sure they are tigh and apply silicone to them

spoiler tighten bolts apply silicone

rear sunroof drains. remove carpet from sides of trunk and examine tubes make sure they are connected and exiting the rear of the vehicle
hope this helps

ok thanks ill take a look. i think its got to do with the brake light because the water comes pouring out from under the lights when i open the trunk

oh from behind the center tail on the deck lid correct? ya unfortunatlely unless you want to epoxy the enitre thing to the car you won't be able to stop that one. that'* not a leak it'* just pooled water behind the tail

**** really so there nothing i can do?
