Help..four years ago this month my rear passenger door started leaking...when it rains there's a puddle on rear floor on that side..son and I argued about cause, took to service station they said nothing they can do..I've hung tarps, shower curtains, etc on that side of roof covering seam of door...they always fall off. ..I have to keep huge pile of dry rugs and towels to sop it up ..in Winter it freezes like a little slate pond..in summer I leave door open facing dun to dry it out...last month I noticed the OTHER door is leaking too! Any suggestions? Don't know if it's done any damage.. someone suggested having holes drilled underneath do water can drain out!!??
