Roof Leak

[Ron Sz]

I've had my 1998 S70 2.5D for almost 2 years now. It was some months
later when it rained really hard that I discovered that the 'old lady'
leaked. The point from where the rain drops fall into the cabin is
lighting console at the top of the window, directly above the auto gear
shift. I've tried (re-)sealing the rubber seal at the top of the
window, but none or little improvement ... in other words, I'm not
sure. Has anyone got any ideas how it might be coming in? I was working
for a few months in South Wales when I first discovered it (it seemed
to be always raining in the Rhondda!). The amount of rain in the
passenger-side (to the left of the driver) footwell was not
insignificant. Additionally, is there likely to be some place that
might be acting as a reservoir.
In all other respects I am very happy with the S70, despite the diesel
having done about 145k and sounding a bit like a tractor at startup.

Any help in tracing this annoying leak will be much appreciated.

Assuming this is a factory fitted sun roof, sliding type, the seal is
more to seal against noise/wind. The water should be carried away in a
gutter to a drain.

There is a centre channel that may move with the sun roof to catch the
water from the rear of the sun roof, check this is in place with the sun
roof closed, if you can pull back the sun shutter.

Check the drains are working by pouring water into them with the roof
open. These are at the sides above each door. Sometimes they can get
blocked or kinked. There will be tubes that go forward and backwards
from each corner of the sun roof. Watch for the water comming out onto
the road.

Check the water is not dripping somewhere else outside the drains. The
seal does need to seal against glass, and if the water is getting down
this interface it may not drip into the correct place. Get an assistant
to pour water on the sun roof with the sun shutter open and try to see
where the water is going.

If the seal is the problem, silicon around the glass/rubber join should
help seal it at least temporarily.

If you still can't see the problem you are going to have to start
removing the head lining.
