Sloshing Noise - Water in the Sills? Mk1

[Gillet]

The issue is that particularly after heavy downpour there is a heavy sloshing noise, lots of water trapped somewhere, it appears to slosh from the back to front of the car on the drivers side, and I'm assuming its rain water trapped in the sills.
Presumably there's some drainage holes somewhere that need to be unclogged, but where would I find them? what am I looking for? The car is insanely low and I'm a big bloke so can't fit my head under there to have a look, will have to borrow a jack this weekend if someone can help me on where to look?

muchos thanks in advance, am still loving my 21 year old beauty after 5 years of ownership, she always does me proud so I should probably start looking after her.

Drain holes in the sills. Near the jacking points. Get something small soft and pointy (Biro cap?) and have a poke about. Also check the tube that go's down from behind the seatbelt towers while you're playing with such things.

Oh dear, if there's water sloshing and you don't know where the drain holes are after 5 years (therefore they've never been cleared ), I fear for the condition of your sills inside!

Cheers for the info, will have to look into it tomorrow.

The water is staying in the sills because the sill drains are blocked but it's probably getting into the sills because the hood drains behind the seats are blocked. Water shouldn't get into the sills in the first place
