So theres definately a leak in my trunk.I dont think its coming from my taillights cuz i have gaskets for both taillights.When i open the trunk and try to feel where the water is its right in the center of my of the trunk,On the cardboard piece.And it seep through,so theres hella water down where my spare is at.Could there be any other spots where the leak can from from?Any suggestion/help is greatly appreciated.thanks

 

is ur trunk sitting flush with the car? (no gaps)

 

My girlfriend has the same problem on her 98 EX coupe. Do a leak test. have one person sit in the back with a flashlight, and a person with a jug of water. Pour at the top right seam of the window. If water starts running down, then move to the bottom, and pour, and stop. Move up until you find the leak.

Hers are at just about the center on both sides of her rear window

 

ill try that.Any more suggestions?
