Mine has a bit of condensation in it. A fair bit now. I was going to remove & set to with a small flat head screwdriver, until things felt like they were on the verge of snapping, so i thought i best not & i should come & ask before going any further
How do i remove this then? I don't see any screws. I was putting the screwdriver in between the black plastic bit on the rear windscreen & the beige cardboardy bit.
