I have had my mechanic look at the car 2 times and he can not seem to figure out why I am having water flooding into the drivers floorboard. This only happens when the AC has been running. It varies from light to almost 2 inches standing in the front and back floorboards? Any suggestions?

Hello,

It sounds like the evaporator is draining inside of the vehicle.
The evaporator for the ac will accumulate condensation as the A/C runs. The condensation gets drained to outside of the vehicle by channels in the evaporator case. It sounds like there is a clog in the drain, which making the condensation drain inside of the car.

So you will have to get that drain tube cleaned in order for the water to drain outside.
