Hi all, looking for any help. After heavy rain last night I have what sounds to be gallons of water sloshing around under/in the rear passenger floor boards of the car. Its not inside and the carpets are wet. I know its a dunroof drain issue and I'm working on fixing it, but can anyone offer any help on how to drain it out? Is there some sort of drain plug that can be released? Thank you so much in advance.

 

The maybe hundred or so cars that came into my shop fill with water - after removing the carpets we used shop vacs to remove the water. There are no drain plugs. We would hang the carpets out in the sun (after vacuuming as much water as we could) and it would take several days for them to dry.

On the other thread you posted to - someone on that thread suggested drilling through the floor to drain the water -

 

Thanks for the reply. The carpets and inside are bone dry. I guess I'll look at drilling holes at this point.

 

The carpets can be a thick as 4 inches - with 3 1/2 inches of that being foam rubber - you WILL find water under the carpets, and the foam will be wet. It may not have seeped through the plastic layer on the backing of the carpet - yet - but the water is there in the foam. If the water gets deep enough it will damage the amp for the infotainment system. (under the passenger seat)
