Gary Howell <(e-mail address removed).net> says: Under the windsheild at
each lower corner, holes rust through. The best fix is to remove the
windsheild and have the body work done properly. The cheap fix is to
remove the windsheild trim and fill the holes with RTV. The holes are not
always visable to the eye, sometimes the holes are under the glass or like
a micro screen.
If a speaker wire has been run through the door seal, water will
sometimes follow the wire past the seal.
