Hi, I also am having a water leak in my 03 Bonneville. Could you please send information to me on what to do. I do not have a sunroof.

In another forum here you said you had replaced the left rear door's power window motor. It you did NOT have a leak before that, you most likely need to reseal the thick plastic layer that is over the metal of the door but under the inner decorative panel. The gooey sealer on that plastic is not usually resealable after this many years. It needs to be freshened with a tacky strip of "caulk." The most important part is the "W's" that are formed at the bottom and they should be located right at the bleed holes in the metal so that the water is forced out into the metal of the door and drips out the holes on the bottom (look to be sure they're open).

Otherwise the water travels on down the plastic, then under the decorative panel, and drips onto the door sill and flows into the carpet in the back.

I'll look up the link for a good picture review of doing this --if it still exists-- from Pontiac forums a few years back.
