HELP! Water leaking in cab!

[Big John NYC]

Hello People,
Has anyone experienced water leaking into the cab of there truck?
My '02 Escalade in getting water in the passenger floor board.
I checked and blew out the sunroof drain tubes so they are clear.
Today we had torrential rain in NY and again, the passenger floor was soaked.
Any ideas what it might be?

TIA,

One of two issues, the a/c drain is plugged or the heater core is leaking. Take a white towel and soak up the water, if its clear then its the a/c drain and if orange/green, heater core.

if from the rain your leak could be from the door seal not sealing properly, it could also be your windsheild seal isnt in best of shape and leaking around that


however it could be what greg just said

The water is definitely clear.
Where is the a/c drain located & how do I get to it?
If it's the door seal I can't see how.
The inspected the seal and it appears to be in good shape.
Would it have to be damaged or does the water some how get under it?

Thanks for the help so far people this has been driving me nuts.

door pins wear out doors gain slop. take a dollar bill and place it in between door and the cab. now try to pull it out. do this every couple inches as you go from the mirror region to the end of the door. if the dollar slides to easily this could lead to a leak. my blazer had this issue, cure is roll down window and tweak the frame of the door till it seals good against the seal. check with dollar to see if it improves
