Hi all - great forum and pleased to register and join you all.
Just purchased a manual 1.8 litre 1997 Mk 3 CL Hatch for daughter No. 1 to drive (she has finally got her licence at 23 on her fourth attempt!)
But recent heavy rains in Qld have shown an alarming problem with copious water egress into the front passengers footwell. It seems that water on the windscreen just runs down to the base and straight into the vents, and into the footwell/carpets. There is a 1.5m black rubber strip that runs across the two "windshield water deflectors/rain trays" at the base of the windscreen, but it doesn't lay flat or even touch the glass at all and water just pours into the pollen filter on the passengers side. It may be a "Clark Rubber" type or el cheapo replacement, but it definitely isn't up to the job of keeping the rain out.
What I'd like to know is if there is a genuine VW rubber strip that keeps the water out? Available from a dealer or online outlet? This car was always previously garaged by the previous owner, but is going to have to spend its life parked outdoors in all kinds of weather.
Common problem that. You wont be able to get the rubbers from VW, but can get replacement windscreen water deflectors (the whole plastic bit).
The rubbers need to stick to the windscreen to create a good seal. They aren't cheap.
I'd take them off and give the pollen filter area a good clean out, then black silicone them up, for a cheap solution. Get the part numbers off them while your in there. You'll have to take the wipers off to get to them.
If your getting water in and on the floors, try draining the air boxes, in the engine bay against the firewall at the bottom is a small rubber flap, open it up and let it drain out. Note that if a lot of water comes out of this it may be the heat core is gone, which is a big job to replace (full dash pull out).
I had the same problem, thought it was the windscreen rubbers, but it was the heater core
Thanks Mattross, much appreciated. Wehad to remove all the carpets (front & back) and let it all dry out.
Temporary solution is an 18" strip of PVC duct tape across base of windscreen on passengers side deflector to keep the water out of the airvent intake. Took the two hard black plastic rain tray panels out last weekend (and buggered up the clips as well) and removed a small amount of debris in there, plus cleaned the filter. Seems exorbitant to have to pay over $400 for genuine VW rain trays when all I need is new rubber seal to run the width of the windscreen.
Heater core may also be a problem as we've discovered that whilst the a/c does a really good job of cooling the interior of the car, turning the temperature knob towards warmer produces no heating effect at all, just a dusty/musty smell of barely tepid air through the vents. Maybe the core is blocked (sounds like another job for Dad this weekend!)
