Corsa C 5-Door: Identifying Cause of Wet Driver's Mat After Heavy Rain & Wiper Motor Repair

Hello,
As in the case of the 5-door Corsa C, 10 years old, after heavy rain I have a wet driver's mat in several places. There are wet squares under the rug too. I managed to remove the felt cover and come to this car's mute sponge, which is also soaked with water. It looks like the leak is either from above in the area of the pedals or from below under that silencing sponge.
I have had these problems since the electrician repaired the mechanism and the wiper motor ...
Under the hood, I cleaned the water drainage channels from soil and leaves and generally what is happening directly under the glass, but it is difficult to locate such a leak
Does anyone have ideas or experiences where this could be coming from?

Water may enter from the wheel arch - rotten sheet metal, in the area of the sill and the beginning of the fender, or from the top near the windshield.
Weigh with water and pour and watch.
There may be a hole under the seal.

It can also leak if the sunroof drainage is not connected (if there is one).

check the seals on the door - bank it - maybe the door was replaced

The reason for the water appearing on the driver's mat is a rotten gasket under the fuse / relay cover, which is located under the shaft. Access only from the side of the engine compartment. You have to remove the plastic cover of the canopy and then unscrew the fuse cover.

Buddy, I have the same problem since I replaced the wiper mechanism and the motor, I have water on the carpet and this sponge over the clutch pedal is soaking for me, how did you solve it ??

Maybe the water does not drain out under the pit and there is so much of it that it overflows inside?

When you unscrew the fuse cover under the shaft, there should be a gasket in the lid (or in fact its remains), you need to clean it and paste a new one (foam to the windows). After the problem!

OK, I will check and I will definitely write back where it was raining because it always makes me do something with this car, hehehe

Gentlemen, I have a book of COrs c I also repair a catalog myself and nowhere, but nowhere are there drains under the hood shown and now I do not know what to do with what can someone have a diagram or something to do with it ?? in which places are these drains and the gasket under the computer is good, where the cables go in this plastic box.

Hello
I also had leaks in my Corsa, such as in the description. I advise you to check the gasket from the computer cover !!! During the rain, the water flows there, the gasket went wrong for me and it's good that I insisted and undressed because there was water under the computer !!!! And all the "experts" said it was impossible.
Regards

When you lift the bonnet up, you have a plastic cover. You have to disassemble it. In most cars, you have to unscrew the wiper arms first and the plastic comes off. If the car has been standing somewhere under the trees, the drainage channels may be blocked. When you clean everything from leaves and dirt, on the left and right sides of the fender, but as if from the engine side you will see technological holes (pen diameter) that should drain the water down. After cleaning, take a bottle of water and pour it over there when the water starts to flow around the front wheel, the channels are clear.
Additionally, check the fuse box as above. She also lets go a lot.

More precisely, when you enter the filter replacement instructions http://www.filtron.pl/katalog/instrukcje/1081k.pdf in the first photo you can see the battery and between the battery on the fender, look for these holes in this depth. Similarly on the other hand.

Hello, I had the same problem Corsa C 1.3 cdti 3 door from 2005, water on the floor front and rear on the driver's side. I will write a short description of how I solved this problem. Each of you may have different causes, so I advise you to start by checking out some simple solutions. Firstly:
1. I removed the carpeting from the entire floor (unscrew the front seats and remove the rear seat, seatbelt fastening, sills, plastic cover from the gearshift and handbrake, plastics on the left and right sides at the bottom of the wheel arches).
2. I carefully cut out a part of the soundproofing sponge. (There was a lot of water, the carpet took a week to dry and the sponge took 2 weeks to dry at about 15C).

Water was flowing between the clutch and brake pedals.

Later:
3. I unscrewed the wipers, the plastic cover from the windshield.
4. From the inside, I disassembled and disconnected the brake pedal with the servo.
5. And then we have access to the partition. There is a metal sheet (approx. 40cm x 40cm) screwed from the engine side with four screws. Sealed with silicone. At the bottom of the motor side, this silicone didn't seal well. And in my case, that's where the leak was.
6. You have to unscrew these 4 screws and tilt the plate inwards, remove the old silicone halfway up the plate and put the new one and then press the plate with screws, remove the excess silicone.
7. After the silicone dries, it is good to cover the joint with "paint", which protects the bottom of the car against corrosion. I currently live in the UK and bought a "Hammerite Underbody Seal" from Halfords store and the silicone I used was "Evo-Stik Liquid Metal".
It is laborious, but nothing has leaked for a week. Only today will I install a sponge under the pedals and a carpet on the floor.

Hello, I had the same problem, Zona complained that her feet are running out of water after pressing the clutch pedal, the worst thing in the morning is because the water is cold.
So I took off the wiper (I advise you to do it with a puller so as not to damage anything), then the plastics from the shaft of the entire wiper mechanism and remove the washer tank, it looks like this,
there are three holes visible (they should probably be blocked) and next to it there was a gap on the left side marked in red and I sealed it all with silicone with a tube gasket for 5 PLN and it looks like this after sealing
This must be done conscientiously and without removing the wipers and the washer tank, it will not be done, best regards and good work.

Suggesting the above solution, without thinking, I closed the holes, but it turned out that my friend was raving like broken ... they are responsible for the drainage of water from under the computer box and there is no way for it to get inside. Blinding them will exacerbate the problem, as the water will not drain until it collects enough to flow into the central drain. Stupid work and waste of time.

The fault is a rotten gasket on the computer cover. Water gets inside the box and when the car is started it is poured inside. The photos show how much it collects in the box. I decided to disassemble the entire piece, remove the water, sprinkle all joints with the preparation, and seal it with silicone. No one has visited it for 14 years, so it won't be soon. In addition, I plan to make some additional cover so that the water from the pit does not run down the casing.

Hello,
I also have a problem with the water on the rug. Just today I dismantled the car and took the cover off and in fact the seal was damaged and it was definitely the fault. And I have a question, can you buy such a gasket because it's hard on the net or what to replace it with? thanks in advance

This seal is only in Aso.
But people write that they put the window sealer and silicone in it and it'll be git.

Post No.8. I wrote about it 5 years ago. In my case, she keeps her to the windows to this day, nothing drips, my feet are dry.

The same problem flooded the chamber in the pit with fluidol and the problem resolved.

Today I also took out this whole computer cover and the gasket is degraded. I sealed it, we'll see.
Naturally, the water was in that box.

However, the water flew through this fuse box, on the under the windshield, I replaced the gasket and the car was dry. thanks

sorry little error, not cover the fuses, only the computer, the smaller one and of course the water was inside.

I sealed this box and so on there is water pooling under the rug ....

I have already written what helps / can help proven.

I was working on the topic today. The bulkhead wall / black box is a hard rubber gasket and just after so many years it does not fill as it should be glued to the paste before twisting the test, the water does not leak. I am very grateful for the photo relations definitely useful!

You will set up a new topic - they will write to you that it is duplicated. If the author of the post is misleading and covers the factory holes for water drainage, then the topic needs to be straightened.

Hello, and in my case, water was getting through the cracked sealing under the server.

In these chests you have to remove the brake servo and seal it, I made a lot of them, here is the problem, not any silicone, but the best glue for windshields.

Hello. Is that what you're writing about? Symptoms such that after a downpour in the morning I had a wet carpet under the feet of the driver and the passenger behind him. Nothing was on the feet. I lay down with a flashlight, uncovered the carpet as far as I could and my friend poured water from a bottle onto the glass. Well, this is where the leak appeared, but I don't know if it is exactly the sheet under the servo? Couldn't take a better photo in these conditions.

Hello, I have read the above threads and typical traces indicate a leak in the area of the servo and the computer box on the driver's side.

However, in my case, the problem occurs on the passenger side.
The carpet is wet for the front passenger (slightly wet) and right rear passenger (very wet).
It's definitely not leaking from the top, the antenna is original.
Door seals in good condition, healthy sheet metal.
Where should I look for the cause of water appearing on the passenger side? Can it flow from the servo side to the right side?
Remove the floor immediately?

Patient: Corsa C, 5 doors, without sunroof
