Its raining heavy outside and i just got into the car to drive to the shop.

turned on the heater fan and water started to pour down from somewher underneath the glovebox.

carpets are soaked...

Any idea how to fix this??

Where is all the water getting into here from, i think some seals at the windscreen or engine bay must be leaking

its a nightmare!

See my thread here:

I believe it may be the same problem!

Clean all the rubbish out of the plenum chamber drains, they block up and the water rises and comes in through the heater. You may have to remove the plastic trim around the wipers, the clips do not always come out in one piece so you may have to get some from your dealer.
