Leaky Buick Rendezvous

I own a 2003 Buick Rendezvous, which several months ago started to have a water leak in the front passenger area (coming from under the dashboard). I’ve tried a local mechanic and a body shop but neither place (highly recommended by friends) could locate the source of the leak. It is obviously water (not coolant), and the volume suggests it is from the outside of the car and not condensation from the AC unit. Any ideas or suggestions? Thanks, Panhandle Ed

does your buick have a sunroof or moonroof?

I had the same problem! I assume you have a sunroof. The drain tubes get plugged up. I used a clothes line wire to “uplug” them. They drain from the front of the sunroof area to down in the wheel wells. Two minutes and the problem is gone!
