2005 Es330 Ac Evaporator Drain Hose Location

[MPatrick]

Can anyone tell me where the 2005 ES330 AC Evaporator Drain Hose is located? Passenger floorboard filling up with water. Want to check that first because there has not been any measurable rain lately. Also, no water puddles under car after driving with AC on.

Can anyone give me a detailed location or picture?

Thanks.

I agree with your diagnosis about it most likely being that the AC drain is plugged. Since the unit is on the passenger side at the firewall, that is where you'll find the drain. I just checked my wife's 04 and it is not visible from engine compartment. Everything is just too crammed in there and too close to the firewall to see, or even get at. I suspect that you'll have to locate it from underneath the car, and will most likely have to remove the under engine splash panel to get at it. A quick call to the service department at a lexus dealership should get the answer you need.
