I've got a water leak from somewhere around the drivers side firewall. Is there a common place that these will start to leak from? I had sitting water in my drivers floor board.

 

Does the vehicle have the factory sunroof?

 

Look up higher like the windshield its self.

 

No sunroof, I didn't see any signs of water marks around the windshield, but I'll check again.

 

Sometimes its behide the windshield youll never see it leaking unless you strip out the dash and stuff.If the zj has a cowl system at all look at that first.And check the drivers door gaskets and the window in that door.

 

If the driver's door panel has ever been off, the moisture barrier may not have been replaced so water running down the glass enters the door and into the cabin instead of draining out the bottom of the door.

 

Thats what happened to my Honda Accord that i drive back and forth to work...the PO must've removed the plastic barrier and the rain water would go down the window into the door and drip into my frivers side floor just under the speaker...it took quite a while to figure that out...its worth taking a look at
