Wet floor

[CaliGem]

Morning all,

Yesterday, whilst cleaning my van I discovered the floor is really damp between the front seats, under the brandrup carpet I have there.
Any idea what may be causing this?

I'm going to lift the brandrup carpet later, hook up my de-humidifier and get a heater on to try and dry it out.

TIA

Common sources are:
1. Blocked roof drains. Raise roof , check front drains look clear, pour water in gutter and it should drain out over the front wheel.if it doesn't, blow air down the drain. Don't poke wire down the drain.
2. Leaking windscreen. Check carpet high up under dashboard.
3. Leaking sliding side windows.

My guess from the choice above from @WelshGas would be the leaking sliding window
above the sink.
Is the thin strip of carpet behind the passenger seat wet too?
