What Causes Water Leakage from the Middle of the Car Bottom?

[SanEmmanuel]

Here are the specific reasons for water leakage from the car bottom: 1. Evaporator drainage: The car's air conditioning system is equipped with an evaporator inside the dashboard. When the air conditioning is turned on (A/C button ON), the surface temperature of the evaporator becomes very low, causing moisture in the hot air inside the car to condense on the surface of the evaporator's heat-absorbing fins. The condensed water is then collected by the plastic housing of the evaporator and drained out of the car through a pipe. 2. Lack of insulation foam wrapping: If the low-pressure pipe is not wrapped with insulation foam, the surface of the pipe can easily condense moisture from the air, and water droplets often condense and accumulate at the lowest point of the pipe, dripping down.
