I have a 2000 Lexus GS300. The drivers side floor keeps getting wet every so often. ?

Q: I have replaced windshield, pulled carpet back and flooded the car with water to check for a leak into the floor board. I have ran water through the drains on the sunroof. I am out of options. It is like there is a bladder the water collects in and then empties every so often.

A: It's the drain line from your Evaporator. It collects the moisture from your A/C and drains it to the outside when your using your A/C. If that line is plugged,broken or removed it drains into the vehicle. You'll sometimes hear the fluid when you take a hard turn but that's most likely your problem. Check under your blower fan and you should be able to see a black hose that goes under the carpet and out the firewall
