307 aircon leaks water into cabin

Tea drinker · 08-07-2010 9:58am #1

Hi folks,
I am driving a 307 hdi at the moment. It is leaking water into the cab and I think it is a blocked vent pipe, but need to get underneath (or get someone else underneath) to check. Any chance it's something more expensive?
Where is the vent pipe located anyway?

Thanks for any replies guys And gals...........!

It could be a leaking aircon/heater matrix. This would mean it's a whole dash out/in job to even get at it.

Have you checked the pollen filter? It could be water coming from that if it's in the cabin. Usually a box in passenger footwell

Hi folks, thanks for the replies. don't think it is a leaky heater matrix as that would leak all the time, not just when a/c is on. Doesn't smell of coolant and the coolant level is not dropping. About the pollen filter, don't think it's that, unless it's holding water from the car wash, it's very dry here.
Where woult the drain pipe be for the aircon? Guessing it somes out of the firewll around the middle? any access to it from the glove compartment?

the aircon generates water when it is working, normally there is a drainoff pipe on it somewhere, the water may have a funny smell off it, my car pours water under the car when the aircon is on, have seen it coming from a few cars, try looking around the heat exchanger area under the dash, you will see the refridgerant lines feeding into it, will be a flimsy looking outfit if it is anything like mine
