I have water leaking from under the dash area on the drivers side near the accelerator pedal soaking the carpet - its a rainwater leak not any water from the air con or coolant. It needs a few hours of medium to heavy rain before it starts to drip dowm mainly behind the inside corner trim - rain appears near the wiring plastic cover next to the sill. I do not have a sunroof - almost impossible to reproduce a leak using a hose - it needs constatant rain. It leaks when standing overnight.
Its a slow drip of water that I can see runs down the wiring loom near the door wiring grommet area under the dash near the A pillar but really difficult to see where it comes from as its literally a few drips a minute.
The wiper cover panel is bone dry but I've added sealant along the underside of the window - no difference.
I've party undone the O/S wheel arch liner - drains are clear of leaves etc.
I've cleaned the door seals & channels.
Added sealant to the rubber grommet where it enter the A pillar plus I've sealed around the door hinges.
Engine bulkhead area is bone dry.
Not sure what do do next - behind the wheel arch liners all is clean with no body rot.
