I have a 2001 Jeep Grand Cherokee and I’m getting a lot of water in the passenger side floorboard. At first I thought it might be loosing coolant through the heater core, but it’s not coolant in the floor. I noticed water dripping out from underneath the side panel and thought the windshield might be leaking
Since that needed to be replaced anyway, I went a head and had that done and she’s still leaking. Today I pulled the cover off of the “A” pillar and there is a blue corrugated tube that runs from behind the dash, up the pillar and through the ceiling. What is that? Apparently this is where my water is coming from. The tube is broken, and breaks very easily (almost dry rotted) and water comes out of it. At first I thought that it could be the back windshield washer fluid line
but that’s not it, it still works. Any ideas?
