Water at the front passenger's feet

[Koen]

Hi everybody,

for about a year i have been the happy owner of a 1997 surf 3.0D. So far it has been a great car and never let me down, although i have been abusing it here in Botswana.

Since a couple of days i have a water leak inside the car, at the feet of the front passenger close to the center console of the car. As soon as the engine is running for a couple of minutes water drips down at my wife's feet. It doesn't smell really and looks clean.
I haven't really had the time to check it properly but tonight i did a couple of quick tests:
- when i run the engine with the heating and aircon off i have no leaks
- when i turn on the heating i have no leaks

Can it have something to do with the aircon? Can it for example be water condensating from the aircon? Is there a possibility of some leak like this in the dashboard? It's now hot and humid here in Botswana so that could explain the quantity of the water.
Any hints are welcome since i don't look forward to taking out most of the dashboard this weekend...
Greetings,

Koen

from the location of where you say the leak is I would say heater matrix

It's easy enough to temporarily cut the matrix out of the system to see if it is the problem. Where the two water pipes go through the centre of the top of the firewall, simply short circuit them. This will allow the coolant to still flow that route but not go through the matrix.

Apparently a pretty horrible job to replace the matrix, there's a write up on how to do it on here if you search. But you wouldn't want to leave it short circuited longer term - you'd have no heating for one thing.
