Gday all

My name is Glenn and am new to the site.My question is, I have a 2005 Pajero and have a water leak that is getting into the aircond vents after rain.When the air is on full blast I am getting a shower.Is there a drain hole below the base of the windscreen somewhere that may be clogged ?.Any help would be appreciated.

Hop over to the Pajero Club Forum for a complete answer.

There is a drain hose from the condensor in behind the dash that gets blocked. Pretty easy to unclog it.
Also they do tend to accumulate crap in behind the guards directly below the windscreen bottom edge that can restrict drainage.

The drain is underneath above the transmission. Poke a wire up there. And prepare to get drowned when it lets go. It's reasonably common as they dont have a cabin air filter until the NS series.

Im possibly thinking if its after rain only then its not the evaporator under dash BUT may be the drains inside the guards ? When its raining heavily the water is not getting away quickly enough from the plenum chamber and the water is over flowing into it. So what im saying is where ever you vent system picks up fresh air from outside is allowing water into it. Easiest way to find where the aircomes in from out side when you have your switch on dash flicked to fresh air, turn your fan on flat out, pop bonnet with engine off (to hard to hear otherwise) and see if you can find out where the air is sucking in then check around it, get the hose out give a good hose down over vehicle and see if any water is getting in and also check around to make sure the water is running out from under the guards (possible blocked drain hole/s) then also cover the inlet for the fresh air and hose down again and see if it stops entering the ductwork...... I had this years ago on my old HZ holden the drain holes were totally glogged from leaves/dirt etc and when it rained it would overflow into the fresh air inlet and fill the heater box up then run all over carpet......Cheers

Thanks for the advice,I poked some wire up the drain tube, about 500ml of water came out,lucky I was on a floor crawler and was able to get out of the way of a drowning.Bugger of a spot to get to as well.
