Where is the air conditioner drain located in 2000 Toyota Echo?

In a 2000 Toyota Echo, the air conditioner drain is typically located on the passenger side of the vehicle, near the firewall. It's a small rubber or plastic tube that allows condensation from the A/C system to drain out of the vehicle. You can usually find it beneath the car, just behind the engine bay, and it may be helpful to check for any blockages if you notice water pooling inside the vehicle.
