I'm sure Ive read what causes this but I cant remember so could someone
enlighten me?
It's definately rain water and not coolant, I had the thought it was the
sunroof drain blocked?.
what ever it is could do with some advice on how to drain the water feature.
The car is a '87 900 T16 with factory fitted sunroof.
Thanks in advance for your thoughts.

I think this came up here just recently... it could be the drain at the bottom
of the well where the AC evaporator is located (underneath the vent in the
hood/bonnet). Leaves tend to get down there and clog things up. I think if it
were the sunroof, you would be seeing water soaking through the headliner
around the sunroof opening.

Most common cause is the ventilation air intake box - just under the cut
slots in the bonnet (hood). At the base of the box is a drain tube,
about 1" diameter, which takes water out of the box and through the
inner wheel arch. Check that this is clear.

Second most common cause is sunroof drains. But check the first one first.

Make my situation the 3rd most common. I had a leak in the windshield.
I checked the first two most common causes without success.

Really? That is really rare in a C900. Where was it coming in?

the ducks are moving in!

the air box drain is clear and so I dont really understand how the water
that is supposed to get from sunroof to outside does it.

where does the drain run?

where does it empty?

where does it normally block?

Why does the water back up onto the floor pan?

its got to be the drivers side drain hasnt it?!

its the first time its even got wet so its got to be something substantial
to just occlude the drain.

if its not that then my girlfriend probably dropped a litre of bottled water
in the car and not told me! LOL

4 drains, front ones run along the A pillars, back ones along the B pillars.


> where does it empty?

Through holes at the front and the side of the car.


> where does it normally block?

Usually at the top, sometimes at the bottom.

When it rains, it gets into the sunroof gutter, which fills up then
overflows onto the inside of your car. It rains inside the car.


> its got to be the drivers side drain hasnt it?!

No, it all depends on the inclination of the car when parked. Nose up?
Down? Level?

Could be that...

There are drain tubes from the headliner's front corners, and on mine when
it did this the drips came off of the plastic trim around the sunroof
without making anything else wet. Check 'em anyway, genty, so you
don't push them off in the process or things get messier.

Nobody expects that...

'97 900s:
At the base of the w/s there is a plastic 'plate' that fills over the
wiper motor & 'trims' the opening.
The plastic plate has a double stick tape strip at the glass. IF this
bonding strip opens(drys out,poorly refitted), ALL the water from the
w/s POURS into the 'body/compartment filter' then to the floor.......
