leak from behind dash - 96 2 door

everytime we get a good rain , i have a wet floor mat looks like coming from behind the glove box . any ideas what to check out?

Windshield might not be sealed all the way. I have that problem with my '04 Impala. Other than that, look anywhere there is a hose or duct in the area that goes thru the firewall.

Check where your blower motor mounts to bring in the outside air, usually there is a seal there that goes bad after a decade or so

x2 on this ,

Also Depending if you have deleted the Roof rack , there is a channel that runs down the sides of the truck that soak the front corners of the headliner dripping Water ... don't ask how I figured that crap out

Im having this same problem, only thing i could see when i poked around behind there was a small hole in the black plastic... Wasnt sure if i should just plug it? I dont want anything filling up back there, i'd rAther just clean it off my mat >.<

Mine does it too. It took me about 2 years to figure out that it started happening when SafeLite replaced my glass. When it's been raining and I cut on my AC i can hear the blower wheel throwing drops of water around. I have cleaned out the blower box and the drain tube is not clogged. Where exactly is this seal you speak of?

had to do some wiper motor work yesterday and had the cowl off. i had a good look around and put a garde hose on all throughout that cavity. i replicated the leak.. i do suspect its what donnie said behind the blower box. the water was draining properly at the rear side of the fenders , so i know nothing was plugged with debris. now i just have to take the time to pull all that junk out to take a look. my question is, is there a replacement seal? or should i use silicone or weatherstrip etc etc?
