HI guys, new on here but i need a hand....

Picked up my first car a few weeks ago, its a 1.2 corsa merit (5dr), and i've got a puddle in the drivers footwell and a smaller on in the passenger footwell, i've found that the water is dripping out of the footwell blower.
Any ideas on what this could be?? Is it a problem with the pipes i.e: have they been attached wrong???

Cheers

Dave

its sound like a heater matriz under the dash.one went on my astra td as it was a work horse i bypass the pipes.
