1. Open the hood of your vehicle and locate the evaporator core housing, which is usually located behind the dashboard on the passenger side.
2. Look for a small, rubber hose coming out of the bottom of the evaporator core housing. This is the air conditioning drain tube.
3. Follow the drain tube to see where it leads. It should lead to the outside of the vehicle, usually near the firewall on the passenger side.
If you cannot find the air conditioning drain tube, or if it is clogged or damaged, you may need to take your vehicle to a qualified mechanic to have it repaired.
