1. Water accumulated on passenger floor after a very heavy rain. The car is exposed to the elements including spring and fall 'droppings' from a variety of trees. The engine always has some debris on it, e.G. Maple tree keys. Because the cabin air filter is partially wet, I assume the drain for the cowl vent screen is plugged with 'droppings'. I could possibly use air pressure or wire ram it if I knew where the drain was. Where is it or should I just drill a couple of holes in the bottom of the cowl vent? I am considering adding window screen to the cowl vent as I'll then see and remove any 'droppings'. Is the drilling and/or the screen OK with you?
2. Left rear seat belt retractor. I forced the belt to its limit while securing a dog cage and now it will not retract. By removing the 4 bolts (2 - T& B, L& R) will the back of the seat come off and on? Then having access to the rectractor, is it repairable or only replaceable? Can the existing belt be reused?
