hi there! Ran into a small problem today whilst messing with speaker wiring. I did search but couldn't find much on the topic. I found a small puddle of water in my spare wheel well and also a crap load down both sides. I have a nice half rusted jack apparently. I have drained the water but i have no idea where to look first to fix it. Boot seal looks fine and i checked the taillights which are still stuck on rather well. Anyone had this before or can advise where else to check? any help appreciate, thanks!
