Drivers Side Floor Wet

[nemisis]

I have a 1990 Toyota Corolla Hatchback (AE92). I left my car at a mates for a few months so he could fix a few engine problems whilst I was overseas. The car was not driven and was left outside. After some rain, my mate told me the floor of the drivers side had a big pool of water in it, and I saw this too. He seems to think some sort of drain hole is blocked, does anyone know how to fix this? He mentioned the front right wheel arch to be unscrewed and drain holes cleared? We ran out of time to check this.

It's not coolant by any chance? you could have a bad heater core

Heater core would leak into the passenger footwell, not the driver's

Hi Sam_Q, as in my original post, the car wasn't driven and was left outside for months.

ah good point, and I guess even if it was to go due to it sitting around then it wouldn't be "a large pool of water".

 

One of the drain holes to look at it at the bottom of the door, pulling the door card off to see if the door is full of water would be a good place to start

Another place to look would be the firewall plenum - take the black plastic wiper-linkage cover off and look to see if the firewall is full of leaves and crud

So, remove the door trim and there is a drainhole somewhere there?

Thanks, I'll take a look there too.

I've removed all the Phillips head screws attaching the black plastic/wiper linkerage cover off (a out 8-10 screws), removed the caps and then nuts from the windscreen wipers so I can remove the whole black plastic piece, but I'm having issues removing the windscreen wipers - looks to be alot of debris under there.

Wiper removal should be as simple as popping the little black plastic cover off the pivot point (if it has one), then undoing the nut and pulling the wiper arm off the spline.

Maybe it's a bit stiff, I'll try again.

The wiper arm is spring-loaded against the windscreen, which can cause the arm to jam on the spline if it is still folded down - try folding the arm up (as if you were going to wash the windscreen with a squeegee at the servo) and then pull it off that way, should be much easier (and don't be afraid to give it a bit of a wiggle and shake to loosen things up, WD40 could help too)

lift up the carpet and pull out the black plastic bungs in the body, that will let the water out.

 

if its as bad as it sounds, you want to remove all the carpet and leave it in the sun for a few days anyway..

 

your car is going to stink:P

OK, some success. One drain hole (passenger) seemed a bit covered, the driver's side was "probably" ok. Anyway gave the whole area a good rinse, and ran the hose in the driver's side drain hole (and passenger) for a few minutes and didn't see any water come in the driver's side floor.

The car is all dried out, been that way for a good month as I've been garaging it and not driving in the rain. Next rain we get will give it a good test.

I'll look at the black plastic bungs as well under the carpet. Need to re-attach the wipers now.
