Question

Why is there water on the floorboard of passenger side of my car?

The passenger side floorboard of my car has gotten wet? What could be the cause of my floorboard of my car getting wet on the passenger side?

Answer 1

If you're getting water on your floorboard on the passenger side then look to see if your air conditioner condenser drain line is clogged.

That is if it's truly water and not coolant. If it's coolant leaking into your car then you have a bad heater core.

But if it is just water then it's likely a clogged condenser pan drain line.
