I have a 2008 GT that after it rains (even if the car has just been sitting in the driveway) water pours out from under the dash on the passenger's side during acceleration. I have ended up with as much as an inch of water on the floorboard.

Any ideas?

Thanks

 

bad windshield or window seal most likely, but it could really be coming from anywhere. I had a problem with an old car where water was pooling in the passenger floor. Turned out to be coming from a bad seal in the sun roof.

Check the windshield and window seals for damage, or damage to the metal the seal is in contact with. If you find any, take a hose and trickle some water down that area and see if water starts to come out of the dash again (maybe take the glove box out to help). Good luck...

 

Found out the drain hole under the black plastic cowling under the wipers was plugged. This allowed rain water to overflow into the air in take for the blower motor. Unplugged the hole and no more water inside.
