leaky trunk lid - help?
did a quick search on this and found nothing about this exact problem.
its been raining the past couple days, and ive had the occasion to get in my trunk. ive noticed something that strikes me as alarming. any time i open the trunk, i get droves of water cascading into my trunk. but this is ONLY when i open it more than about halfway, and its coming from right under the carpetting on the lid. only the very bottom portion of the carpetting is wet [like, the extreme bottom, maybe a quarter of an inch total], but there is an extreme amount of water building up. im going to pull off the carpetting wednesday and see what i can find out, but im concerned that its hidden behind the metal bracings, where i cant get any caulking to. what should i do about this?
if i get the trunk carpetting off and find that its a leak somewhere where i cant reach, would it be in my best interest to just take it to a dealer and donate an arm and a leg?

oh bloody hell.
i dont see any reason that wouldnt work, but that wont stop the rust, am i right?
EDIT 1:
so in my words: take the spoiler off like you would a big badge plus 4 deep bolts [similar to the trunk applique] and resilicone it? with a stop-gap measure being to open prefurnished but plugged drain-holes currently holding the carpet up.
Simple solution - Remove rubber plug(*) on bottom interior of deck lid which will then allow water to drain while the lid is down rather than having it accumulate and then pour into the trunk when opening the deck lid and watering packages inside.
EDIT 1:
Remove the trunk lining then 5 each 10mm bolts, you will need a deep socket.
Use a piece of dental floss to cut the spoiler off (cut thru the silicone).
Now clean up the trunk lid and spoiler of old sealer, wash and wax everything and re-apply new silicone and bolt it down.

summary from proper use of the search function (which would have made this thread unnecessary):
remove plugs from bottom of carpetting.
- this is not a fix, it is a stop-gap to keep water from soaking your trunk when you open the lid.
the real issue is the spoiler is not sealed properly. to fix this you have to take the spoiler off, clean it [so that you get a clean seal when you put it back on], and re-silicone it on.
- this is a fix, as it addresses the real issue, not the symptoms of the issue.\
pretty much got it? [thanks boost, for not hitting me in the face with a keyboard]

I'm not sure what additional information you may have found with your search, but if you need more, here'* a TSB on deck lid leaks.
Deck Lid - Water Leaks When Opened
File In Section: 08 - Body and Accessories
Bulletin No.: 01-08-57-005
Date: November, 2001
TECHNICAL
Subject:
Trunk Area Waterleaks
Models:
2000-02 Pontiac Bonneville
Condition
Some customers may comment that water leaks from the deck lid when it is opened.
Cause # 1
The CHMSL lamp gasket may not be seated correctly. Refer to the illustration above.
Correction
Important : If any part of the CHMSL lamp gasket is cut, torn, or folded over, the gasket may become unseated and a water leak may occur. Water will run down the edge of the decklid and leak into the decklid, past an unseated CHMSL lamp gasket.
1. Remove the CHMSL lamp assembly.
2. Inspect the gasket for damage. If the gasket is damaged, replace the lamp assembly.
3. If the gasket is not damaged, run a small bead of silicone sealer around the perimeter. Refer to the illustration above.
4. Reinstall the CHMSL lamp assembly and tighten the fasteners securely.
Cause # 2
The decklid rear applique may not be completely seated.
Correction
Important :If the decklid applique is not properly seated, up to 3.8 L (1 gal) of water can run down and collect in the decklid. When the decklid is opened, the water will pour cut of the five drain holes. Three of the holes will drain water onto the rear glass and the other two holes will drain the water into the trunk.
1. Use sufficient force to press the applique into the decklid completely.
2. Securely tighten the applique retaining nuts from inside the decklid and re-test.
3. If the leak persists, remove the nut(*) and apply a thumb grade sealer to the applique retaining studs. Reinstall the nuts securely.
Cause # 3
The rear spoiler retaining nut(*) may be loose or missing. Refer to the illustration above.
Correction
Important : If any of the six rear spoiler retaining nuts are loose or missing, a potential water leak condition may exist. If the water leaks through a loose spoiler fastener, water will fill the decklid overhang and enter the trunk when the decklid is opened.
1. Tighten the six retaining nuts securely and re-test.
2. If the leak persists, remove the nut(*) and apply thumb grade sealer. Reinstall the nuts securely.
Cause # 4
The sheet metal may leak water through welds behind the rear body applique.
Correction
1. Remove the rear applique.
2. Clean the sheet metal with one of the cleaners listed below.
3. Apply seam sealer to the sheet metal weld area. Refer to the illustration above.
4. Reinstall the applique securely.

What I did (and have not had a recurrence of the problem) is:
1) Removed, cleaned surfaces, resealed, and reattached the spoiler. Careful where and what you lay the spoiler on as paint scratches easily.
2) Believe I also put some sealer around the rear brake light (dealer suggested some people thought water could come in from that area - thought it came from a Tech Service Bulletin).
3) Removed 2 rubber plugs at the bottom edge of the deck lid that I couldn't determine any practical use for (granted it sounds silly, but that is the lowest point water will seek when the lid is closed...and it definitely beats "standing water" in the deck lid...well at least until one opens the lid and it then pours into the trunk and then there'* "standing water" in the trunk). Personally I'd rather not risk watering whatever happens to be inside the trunk as it typically is my wife'*. Let me know if you find a practical use for these plugs I've had off for about 1 year now. No problems now! What more can I say.
Now for that front interior leak. Haven't posted anything on that yet as the latest fix has not yet been tested. How many cars can boast "portable indoor pool" on a "For Sale" ad?
