Hi Folks, looking for some information on a water ingress issue, 2010 Autotrail Mohawk.
The problem is located along the offside under bench seating along the body edge. On the outside the van has a 1.8m storage bay door that lifts up on hinges and there is a small rain gutter running along the underside of the door when closed.
We've been drying out the panel with a heater and dehumidifier but I am struggling to find a possible source of the water. I've had the screws out of the gutter and they are clean. I've looked up the front corner pillar on the outside the the vertical timbers look clean as well as the various cables. The only area in question in that upright body part appears to be some expanding foam facing forward toward the front. It looks sound from what I can see, without taking the rounded upright off behind the drivers door. I've put a small bead of silicon on along the rain gutter as we cannot get it into an NCC place in Stourbridge until the 8th of June.
The water system is drained and I can see no signs of damp or water on the inside of the van, on the ceiling or walls. All round the windows is dry and clean also.
The damage is forward of the TV antenna and solar panel inputs also and on the roof there are no drainage points on those front corners. If it was something on the roof, I'm sure I would see some signs of water higher up, but this is the base of the van along a metal strap that is bolted through the body. I wonder if there is a rubber gasket along that bracket that has gone flaky?
Unfortunately I had to drive last Friday 21st May and the standing water on the M42 was horrendous, so that cannot have done me any favours. I am now refusing to drive in the rain (such a diva!).
Any CSI types out there who may have seen this, please get in touch. Thanks.
