I have a 2007 Grand Caravan. While parked, if it rains, water builds up somewhere behind the brake pedal so when you first drive off in the van, about a cup or two or water pours out onto the carpet behind the brake pedal. Once that water pours out, there seems to be no more water leaking but hey its then so wet back there its hard to tell.

I tried to find the leak and have brought it to two garages and they can't find the leak either.

Any suggestions?

Thanks

 

remove the windshield wiper module cover and check for debris. that's one of my many ideas.

 

Clean out the drain for the cowl
