I have a 2008 GMC Sierra and the driver side and passenger side floors are soaked I was wondering if anyone had any idea where the water is coming from? I checked the coolant level it was just little under the full mark. A possible seal going out???
Not sure about this, but I seem to have heard - but I don't know where- that there was a problem with A/C drain hoses coming off.
Worth a check but I don't know where I got this from!
Same problem here with my 1991. If the water is fresh replace the windshield will fix the problem...Fixed mine. If the water smells of antifreeze will be something else....
Make sure the ac drain hose is not plugged. this would cause the water to leak out on the floor board. Just get under there and stick a piece of wire or something up the drain hose to make sure it is clear.
