Where is evaporator housing drain?

The evaporator housing drain is typically located at the bottom of the evaporator case in an automotive air conditioning system. Its purpose is to allow condensation that forms during the cooling process to drain out of the vehicle, preventing water buildup inside the cabin. The drain is often a small rubber or plastic tube that extends outside the vehicle, usually positioned near the firewall or under the car. Regularly checking and clearing this drain is important to avoid water leaks and potential damage to the vehicle's interior.
