What is making my driver and passenger side floor boards wet?
(1) Answer
Does it have a sweet smell like coolant? That could be the heater core leaking. If it smells like regular water, it could be your heater box drains are plugged and the water is overflowing from the heater box. Your windshield seal is in good condition?
