My 2000 has water leaks only when it's parked with the front lower than the back. When front is up, no water leak. It typically leaks on both sides, driver and passenger. When washing the Jeep and trying to force water around the sunroof, doors and hood air intake, no water is to found in the cab.

 

It leaks from the engine bay or inside the cab?

 

Oops, inside the cab! I've turned the hose on full force and a trickle around the sunroof, windshield which I replaced (it leaked before the new one was installed) around the door jams (both sides of the Jeep) into the fresh air intake (a/c doesn't work so no leak there) not heater issue (antifreeze stays full). It doesn't feel wet up under the brake or gas pedals are or on the other side up by the firewall. Now I did notice the brackets for the brake arm assembly on the fire wall had rust on them (actually around the whole area) but it has not looked to be wet at the time...I may be missing something there but even so why would both sides get wet? I can see where maybe the fresh air intake....but wouldn't any water run out of the drain tube for the a/c (in the engine firewall? I noticed the it is wet on both sides where the carpet meets the trim pieces...?
