I have an issue with water behind the dash blowing out ac or leaking on foot. The drain tube is there but doesnt seem to be dripping water when ac is on. Could there be something else maybe stopping the water from leaking out

No, no - no apologies needed.
Just trying to point you in the right direction. There are so many postings about water leaks, and almost every possible water leak problem has been discussed before many times over.

and welcome to the site - lots of good info here - just be prepared to spend a lot of time browsing and getting some good ideas on mods, repair tips etc.

 

Welcome to the site, read the posts and let us know what you found worked for you, as you'll see there are a lot of posts as Whopper pointed out

 

i am not sure where to start because it didnt have the drain hose running out of the firewall and added that but it still fills up behind the dash

 

Then the drain is not installed correctly and/or slime mold has taken over the drain tray.
