Hei Johann,

Most of the times leaks are very hard to find the source of. Especially if you car has a vinyl roof. But chances are that water is entering your car somewhere around the windshields, and most likely somewhere near the bottom of the windows.

You could try to find out if the leak comes there by using some silicone around the moldings. If that fixes it, the windows must come out. Then resealing and your back in business.  That is until your trunk starts to leak.

Lykke til!

What is the condition of the body near the rear belt line?  Cadillacs of that era, were notorious for having premature rusting problems, that caused leaks to the trunk.

Ok Thanks Johnny. It can explain the leakage in the in  the trunk. My car have a vinyl roof and and on the left side on the top near rear window I have a rust problem and we repear that but maby the rust go up under the vinyl?

As I remember rust under vinyl roofs was also a major problem with cars of that era.  Look for bubbles in the vinyl.

On the bottom of the fenders there are some drain holes.  Sometime pine needles and other stuff gets in the inner fender and plug up these holes.  When the water has no place to go then it fills up and falls to the inside.  Eventually this is fixed because the fender rust out and makes a bigger drain hole.

I used to do bodywork with my dad and this was a common fix to clean out this area.

Also have a buddy run a garden hose around part of the body while you watch for leaks on the inside.  At least this way you can sometime find out the genneral area of the leak.

Ted is right about that.  My uncle's van in Pennsylvania leaked onto the floor pans and it turned out it was the drains for the windshield clogging up.  Make sure to blow out the drains and hoses (if there are drain lines) with compressed air.  My brother the mechanic always says that water (or oil for that matter on the engine) leaks high and runs down.

johann,  Look under the doors, (doors open) If you find one,you will find the others, take a peice of stiff wire and clean it out.  It is possible that the drains were covered when they sprayed the under-coating on.
