What is your question?
Walter leaks into trunk. As near as i can the main trunk seal is in good shape. Water accumulates just inside the main seal on the right side and runs down into the wheel well. I am unable to determine how it gets in. I think it must be leaking through the trunk key lock or the trim above the license plate. Anyone have any experience with this? I am really stuckand my trunk is wet!

It is best to look for water leaks when everything is dry. Is the trunk seal or trunk lid, damaged in anyway? Does it close flush with body? Ensure the trunk seal makes good and uniform contact with the trunk (particularly important if the vehicle has been involved in an accident). You will need to remove the trunk carpets and trim and sit inside the trunk (you will need a flashlight) and get a friend with a garden hose to spray water around the trunk lid, rear wind screen, and rear lights to determine if the water is entering the doorway. Then spray water around the rear windscreen moving around the circumference of the windscreen. Is there any rust around the windscreen area or body work? If you have a sun roof there is a drain tube at each corner of the roof to channel away water perhaps one is dislodged in the trunk and not venting to the outside of the vehicle to allow water to run out.
I have two 2003 Taurus. Both had water leaking into the trunk. I traced my problem and found the culprit to be the five black plastic fasteners which attach the bumper to the car. They are plug shaped with a philips head plastic screw in them. These plugs go through the metal right into the trunk cavity. You have to take off the black plastic cover that surrounds the opening for the trunck latch. This plate goes across the opening of the trunk and provides a trimmed finish. Takes this off and you will see the ends of these five, black plastic plugs sticking though the metal into the trunk area. The water runs along the outside on the top of the bumper and wickes its way underneath the heads of these plugs. These plugs are not providing a water tight seal and the water seeps in. I took these plugs out, coated them with clear silicone sealant, pushed them back into place and let silicone cure. I haven't had any water leaking into the runk since. I know others have said it's the seal around the trunk but I don't think so. There doesn't appear to be any logical way for the water to jump over the seal and into the trunk.
Remove the black plastic cap that covers the trunk ledge and latch so you can see the trunk seal underneath. Get in the trunk as Patrick suggests to locate where water coming in. On my 04 Taurus I found that water ran along the side of the leal and was channeling under the sealon the right side where in goes under the black plastic cap on the ledge of the trunk through a ripple in the sheetmetal that the seal covered. Removed the entire seal, filled it with black silicone adhesive, reinstalled it, caulked the vertical and the length of the seal that would be under the plastic cap, and closed trunk until it cured. Leak gone. Bill
