So its a good thing I joined this forum -- my niece's 2008 Grand Cherokee seems to now literally be springing leaks daily! yesterday the transmission fluid, now water on the front passenger side floor after a heavy rain. yesterday was literally the first time this happened and she's owned the car for four years. soaked carpet; water running down the passenger-side A-pillar; dripping out of the screw holes. Some, but far less, on the driver's side as well. I've done some research and the sunroof seems the most likely culprit. there's a movement toward a class-action on this too it appears? Anyway from what I've read it's common for the sunroof drain tubes to become blocked or dry out? is there a simple way to clear these out without taking the car apart?

Again it was all-of-a-sudden after a rainstorm, but never before. thx again great site!

 

You can try probing them with a small flexible spring-type drain cleaner. It's probably organic trash such as pine needles and tree seeds. I wouldn't use air pressure for fear of blowing the hoses off the fittings.

I'm going to say something that you should use at your own peril. If the blockage is low and solid, try a LITTLE Liquid Plumber.
