water in passenger floorboard...

[allanonBH]

Ok well I know I can probably answer this one myself... but just to make sure. Other than a door/window seal leak, or the heater core.. what else could cause this? And if it turns out to probably be the core.. how hard are they to replace on a 99 tahoe?

Thanks!

The hose that allows condensation to drain from the A/C system onto the ground might be plugged and allowing water to back up into the passenger compartment.

the big question here is: is it water or antifreeze? if water....probably clogged evap. drain...quite common

That should help. I've had to clear it twice already
