Car appreciation... the aesthetics, the engineering, etc

My mk1 skoda octavia vrs has a big puddle of water in the front and rear driver's side footwells. It's got a lot worse over this last week whilst it's just been sat in the street parked up. The internet says the scuttle's likely blocked with leaves and water's getting in through holes for loom and bonnet catch.

I have no idea how to sort this. What a bollox.

Scuttle panel, usually plastic is panel between bonnet and windscreen underneath windscreen wiper arms.

You will need to get a few tools together, a bucket of soapy water, J cloths (or similar).

Remove windscreen wiper arms.
Lift up plastic over at end opposite to blade. Remove nut. (13 or 14 RING spanner). You will probably then need a puller to slacken the arm off the splines of the operating spindle (Machine Mart, approx. £12 or so).
Open bonnet.
Remove the plastic scuttle panel. On the left and the right you will probably see pools of water. Remove with J Cloth. Rinse out all of the area with the soapy water to remove X years of gunge.
Now take a careful look into the cleaned area. You should be able to see a hole where the water from screen, roof area can drain out. You may have to poke out with a screwdriver blade. Pour in some water, or use garden hose sprayer. You should see water running out from underneath the car.
Job done.
Reassemble.
(Use copper slip on splines when re-fitting the wiper arms)
(Also, whilst you are in there, lubricate wiper mechanism - 3in1 or similar)

Simples.
