Take off the heater intake grilles below the 'screen (where the wiper spindles are).
There are several drain points in here which get blocked with leaves and then flood, thro the heater fresh air intake, into the car.
'98 D 800 van
I did a test with a watering can yesterday. First I cleaned the seals along the edges of the doors - and also the additional sealing strip on the join between the roof and the door, as the passenger seat has had signs of dampness before.
I started by flooding the door with water over the seams - no leak.
Then starting from the bottom of the screen, gradually worked up - no leak until I started on the roof at which point the water started dripping from the inside at the top of the screen. Also the top of the headlining at the pillar started to show signs of dampness. I think the water is entering at the top of the screen and flowing down to the footwell via the pillar. Without dismantling half the inside I don't know exactly how it is getting down there - but that is obviously the weak point.
I only have one berlingo, and it's a bog standard multispace forte. No sun roof or additional panels in the roof.
Looking at the haynes manual - it states the windscreen is bonded in, but there is also a rubber trim strip around the outside. Does this mean the bond isn't good, or does the rubber seal do more than just being for appearance? Does this leak mean I have to have the screen replaced?
I had exactly the same problem on a transit van years ago and was told that the bonded in screen helped with the rigidity of the body. I had the screen removed and refitted and didn't have any further problems. I don't know if the screen in the Berlingo is bonded for the same reason but having the screen removed and refitted might be the best option.
lift bonnet, remove the plastic cover along length of engine bay (below windscreen) and clear any leaves twigs etc etc, this can block the little holes to allow water to escape. or youve the same problem as me, heater matrix up the spout !
Our old Berlingo used to leak into the drivers footwell after an accident repair where one of the seams wasn't sealed properly. I took the carpet up and knocked out the rubber bungs in the floor. I also cut the carpet where it could not be seen so that that piece and the soundproofing underneath could could be taken out and dried.
