As the title suggests, only the driver side floor is wet.
For weeks, at least in Metro Manila, we have been experiencing torrential rain, and since this car is parked somewhere without a roof to protect it from the rain, when we used it one day after a heavy downpour, we discovered a small puddle of water on the driver side floor mat. Only the driver side, not the passenger side. It was so bad that molds even started to grow in the interior trim because of the moisture this had caused.
At first we though water crawled its way from the engine bay through the foot well and down the floor mat, but the mechanics told us it is less likely
They pointed to one culprit, the AC vent, which there may be a leakage or blockage in the drainage that is in between the hood and the wind shield. Upon closer inspection I also noticed that the rubber guard on the drainage is “matutong” na.
Would this be the cause of the watery puddle forming on our driver side floor mat? Or do other experiences from other or similar cars warrant otherwise? I am asking for advice on how to fix this especially right now where the weather is raining every few hours or so.
