I have 2010 Buick Lacrosse CXS. Where are the sunroof drains located, how do I clear them, and check if they have disconnected?

Asked by Feb 18, 2017 at 01:14 PM about the 2010 Buick LaCrosse CXS FWD

Question type: Maintenance & Repair

Found an inch of water on the rer driver side floor. Front seemed OK I'm thinking the sunroof drains may be clogged or disconnected. Could it also be the heating system in the front. I've heard that can clog and send water through the dash and to the floor?

Open the sunroof and look for a little hole in the gutter.
