Water in floor when I turn the vent on!

[schoonover_88]

I have a problem! After it rains and I turn the vent on water pours into the passenger floor board. This leads me to think that the cowl is leaking somewhere.....but I don't know where or how to go about fixing it. Wondering if anybody has any advice. Thank you!

Are you running the a/c, heater or just the vent? Because if you are running your a/c, then your evaporator drain system is fubared likely (condensation from humidity). If it's the heater, it's likely coolant. If just the vent, idk wtf that's all about.

Well, I know that it is only water because it does not smell like coolant...think it is just the vent, but dunno

There is a drain hole on the firewall on the passenger side of the car. It is right by where the header meets the H-pipe. Make sure it is clear and not obviously clogged.

My ld truck did the same thing. It happened because when we changed the A/C out I didnt put the little drain back right and it wasnt in the hole in the fire wall all the way.

Well it didn't happen this time at all, so I really don't know what is going on. I thank you all for your help and advice.
