Subject : 1991 205 GL 1.1 5-door Hatchback. Rain water leak somewhere around the back end. Water gets into the boot area then runs down into the well under the rear seats. It forms a pool, the rear seats (being foam rubber) absorbs the water, result : constantly wet seats, nastly damp smell etc. Have spend many happy hours spraying the back end of the car with a hose-pipe whilst somebody sits inside watching for leaks. No joy. Have replaced hatch door rubber door seals. No affect. Rear window was recently smashed by vandals and replaced - so new window seal here, but still the rain comes in !! Ideas ?
