water damage.....

ok i recently put underglow on my car and in order to do that i had to drill a hole in my floorboard probably the size of a quater dollar...... and now everytime it rains i have a huge ass puddle in my car. now then the problem is if i drilled the hole in the drivers floor board area why is the passenger side the one getting malled by water???? and i still dont see how water is getting in the car if water comes from the sky and the hole is in the bottom of the car???? i am confused please help!

Check your trunk taillights. They are known to leak.

i did notice some water back in that area. do i need to get new ligts or something?????? and would that really cause my floorboard to be in a puddle ?

If it rains hard enough, then water will get into the floorboard.

You can seal the taillights up with a clear silicone. It's a common problem with the neon.
