Hi everyone.. I'm trying to keep my trunk dry as well... thus far:

Sealed the gas filler area/verified the drain tube was clear...all good now
Put in a new antenna grommet...all good now
Pulled the rear taillights and found a hole on the vertical trim mounting grommet that shares the body frame for the passenger rear taillight...repaired and sealed.
Removed the rest of the rear trim body black trim between the taillights, sealed up everything with silicone...all good now.

...and water is still coming in.

It looks like it may be coming from the plastic grommets that are on the inside of the trunk/boot area, right along the top carpeted edge by the bumper. This one sort of has be baffled: how would water even get in there? Isn't it a boxed section of somesort?

Right now this water is getting in with the car sitting...so I can't imagine how bad it'll be if I'm driving the car...I'd rather take care of it now before I put my fresh boot carpet in as well...

Anyone been down this road before? Curious what you did...perhaps i'm missing some sort of drain hole clearing somewhere under the bumper? I read an old post about some sort of revised seal for the 'boot chrome finisher', that had two holes on the later cars, but was blocked on the early cars (mine's an '89). The post mentioned a service bulletin, but I don't see a bulletin referencing this nor additional posts describing this fix...

Thanks!
Pete

 

check carefully along the rubber trim along the lower edge of the rear window,pry off the chrome corner trim,and hose it down.water can make rust under the trim,making large unseen holes.I am currently working on this situation on both of our cars.looks like at least one window pull..ouch...i will post later on this with pics...

 

Actually, I forgot to add that one... I had the same thing. Both lower corners of the rear window, under the rubber trim, had rust holes...fairly specifically located. Got those patched up from the inside, and sealed/etc..

This water is definitely coming from the rear bumper edge of the boot...just not sure if it's coming in directly from those mounting grommets for the rearmost inside trim piece, or if water's just trickling down from the trunklid, and working it's way down there...

Can you put up some pictures?

 

Here's the leaking area - right by the grommet/nuts that hold the rear trim onto the back panel...

 

DayOff,

Did you fix this yet?
