I was deep cleaning my 2003 ZX3 after I bought it and noticed there was a lot of water in the spare wheel well.
I did the usual hose to hatch test and it was coming in from a decent amount of areas. Including behind my tail lights, around the gas cap door, and through tiny holes at the top of the hatch door. I sealed all of them but I still had a leak. I couldn't find it until I took out my headliner. It's coming from a group of sheet metal meetings. So I found where it's coming from, but I could not pin point where it was getting in from.
Here's where it's dripping
I've ruled out any leaks below the red line
and I'm pretty sure it's not leaking from the sheet metal joints above the red line but...
I'm quite certain it's coming from the roof ditch.
I worked my way up the ditch with water and I believe the leak is within the first 5 inches (from the back).
Any other ideas where it's coming from?
If not, how do I go about replacing or resealing the roof ditch without making it look ghetto?
Any help much appreciated!
