There are times when you'll look under your car and notice some drips occurring in various areas underneath of the car. Some of these leaks really do (or should) require a trained eye to determine where they are coming from and if they warrant repair. In this particular case, the client had a concern when they noticed a "clearish" fluid leaking from the center of the car.
Once we investigated the leak on the lift, we realized right away that the "clearish" fluid was simply water. The A/C system is designed to remove the humidity from the cabin which makes you feel nice and cool. That humidity (moisture) is condensed into water as it passes over the chilled evaporator which rests inside a specially designed box. Once that vapor changes state to water, it fills up that box. The box is designed with a relief tube that allows the water to drain out of the box. If it didn't, the box would fill and you probably would have a damp carpet on the passenger side of the vehicle. You may also hear a swishing sound when making left and right turns. A good way to keep the drain tube clear is to clean all debris from around the car and from your windshield cowling screens. Tree twigs, leaves and road debris can enter your HVAC box and get trapped inside leading up to clogging up the drain tube.
