try sorting the drainage like i said it then wait for it to dry out. looks like its overflowed into the matrix. happened in my polo, was fine when i dryed it out.

Well had a look at it again 2day and i think the matrix if ducked, the carpet near the centre console is wet and the heater only works sumtimes now :(

Is the matrix hard 2 change/expensive?

check the pollen filter area, and check for the drainage hole. if its blocked water will get in.;)

Is the car losing coolant at all? Maybe a leak in the matrix.Also have you used radweld on it at all?Id give the coolant system a good flush out with a hose and do it both ways too,thru the stat housing and the header tank and refill with coolant and boil the water over to bleed the system again and see what happens.

tahts what mine done before matrix fuck

no dont think its head gasket. heater works fine.

Tryed the bleading methord 2day but didnt seem 2 work, had the car running for half an hour with the blowers on full and hot and the fan still didnt come on. :(

thats also a common problem with a buggered head gasket mate.does the heater blow warm air at all?Does the car overheat?Checked the coolant for oil?Checked the oil cap for mayo like stuff?

No, not wen stationary.

But thanks 4 that advise, will give it a try 2mora. Cheers :thumb:

bleeding the coolant system is easy, whap your heaters on full, and on hot, take the expansion bottle cap off, and run untill fan kicks in. then leave the cap off for about 10 minuits and it will be bled,

so does it happen when reving when stationary then?

No deffinetlty not coming from the doors.
Only happens under acceleration!
How do i bleed the coolant system then??

try bleding the collant system, might find that is has a slight air lock and this is alowing the water to "slosh" arround...

other than that you sure its not comming from the doors? as the corsa is a wet door, and it might have its drains bunged up

does it happen when you rev the car when stationary?

Under breaking?

Going around corners?
