Water coming from behind dash?

Greetings,
I've just recently come across a little problem with my 95 LS. I've been getting water leaking from behind the dash onto both sides of the front floor carpeting, mostly on the passenger side. This seems to only be happenning when I use the A/C, and I've heard of other cars having condensation problems like this when drainage tubes get clogged and the like. Anybody have this happen to them or have other insight in the matter?

I was given a 92 ls teg that was getting water in from all kinds of places.And one of them were on the passenger side .After days of holding a hose over the car ,I took out the glove box and seen the water was somehow drippin it the a/c flap(the one that opens and closes for inside and out side air) Even when it was shut the water would build up and force it back open enough to leak.Im a DIYer so first thought about caulking it shut .but removed the front windsheild valance and found away to caulk around the area and I think i also caulked something else around the valance,its been awhile anyways 6 months no leak.The car was free so I didnt care about a little caulk here there.Maybe your situation is different.Hope it helps 2dr BuCkeT

the water is probably coming from your evaporator. it's a black box behind the glove that contains your evaporator (looks like a small radiator). the case has a tube that runs through the fire wall to allow any moisture to drip out(the puddles of water you normally see under the car when a/c is on). if that is clogged....it can get into the cabin. problem w/ unclogging it yourself is you have to open up the a/c system (which means evac and recharging freon) inorder to remove the evaporator case and clean it out. lot of work.

I think this is probably my problem, thanks for the information. Doesn't sound like this will be something I'll fix myself. :banghead:
