Just had my first leak issue over the weekend.
Had panels and rear window in place, with midgate folded down. Had full of 8 and 6 foot ladders, bunch of shovels, rakes, tool box, saw-horses etc... Backed in my driveway when got home, so bed was uphill, with front end facing wown hill. Was in very bad rain. Intended to go out and unload stuff to garage when stopped rainng. Rain never stopped, so just went to bed.
Got up in morning to unload, and was a good deal of water had pooled in the front on the seat cover. (Glad had just bought a month or so ago the midgate seat cover from GM parts direct......saved inside). First thought it was just run off from some of the wet ladders and equipment when loaded. But on further inspection, noticed leakage around seal where midgate would be if were closed.
Once closed midgate.........had to soak up a good deal of water from carpet, and under midgate hinge cover from rear floor.
Have seen other posts in other places, is this covered on a TSB? With bed panels, and window in place, midgate down is it supposed to be water tight? Should I go to the dealer with this?
Bought 02/23/02, need to check for build date.
Any help appreciated!
