hows the weather seal around your passenger door look, i had a leak around one of mine on another vehicle i had and it caused a pooling there when ever it rained hard

 

i have seen a lot of water leaks come from the windshield ( not enough sealant ) has windshield been replaced before ??
use some duct tape,, get a water hose , tape a part of the car at a time where you suspect leak is coming from and spray water, hopefully that will help you locate the leak,,

 

Your a/c drain tube may be plugged up. Then the evaporator will not drain the water out the front of the firewall. Try freeing debris with a pipecleaner or a coat hanger. The drain tube comes out below the charcoal canister on your car.

what is up with this guy, ive noticed that recently he has been popping in everywhere saying things that are either wrong, doesnt make any sense, or is something that has already been said or established in that thread. Can some one get rid of this guy or something?

 

Hopefully it is being worked on right now.

 

Update: I really appreciate all the help, guys. It rained a few days back and I was able to see where the leak was coming from. It appears to be from under/behind the glovebox, as indicated in the pic. Could this possibly be from the a/c drain tube?

 

I'd say that is either from the windshield or from the "fresh" air intake.....ac drain tube is to the left of your hand....maybe 4~5 inches. on this gen you can pull the blower pretty easy, might have to pull back the carpet for the added room to drop the motor, then kind of look up into the ac/heater box.
