What could possibly be causing a leak in this spot?
I ran the hose on the trunk area to see where the leak was coming from and noticed a steady drip out of this hole after about a minute or two of spraying water. These holes are on both sides of my trunk, but only the left drivers side is dripping.

BG: I bought this car off of Craigslist for $800 knowing it needed some work (tie rod, hole in exhaust, 205 miles, power steer, ac belt..). Didn't notice that there was a puddle in the tire well when buying but boy do i see it now. It's really not awful- only about half an inch of water and only on the left drivers side obviously. Just smells/looks mildewy and gross... please help lol! Thanks in advance!

Anyway here are a couple of photos of this mysterious leaky hole.

 

Get someone to remove that glass

 

Plan to ASAP

 

Drill a hole in the tire well to drain the water duh

 

Humid air, mold, stinky car. Nah, rather fix the leak
