I recently bought a 2001 Seville sts and have the wet passenger side carpets front and back but not drivers side! I done some research online and found similar issues however I cannot find any pictures of where the drain pipes are for the windscreen area which is where I believe the issue is because I can hear water moving around the front end of the car when im driving!

I Had a look under the car behind the engine near the exhaust but couldnt find a rubber pipe which im led to believe gets clogged up causing this issue, does anyone have any pictures or videos or links to info on where to find the drain pipes so i can try un blocking them?

Thanks

 

You may have a clogged 'evaporator drain pan discharge tube', try googling that for pics. Usually, on the cars I've had, it may only be a rubber elbow, or a short hose, and may not come down low enough to see from below. Try looking at the firewall under the hood with an inspection mirror, and maybe you'll have better luck.

 

If you open your sunroof there's two drain holes. They are clogged. Take a hanger wire and prod softly few times spill some water at the top and see if water drains. If it does your problem is solved. Don't poke too hard you might disconnect the drain pipes. I had the same issue on my cadillac seville sts 4.6 v8 2001 model. It's solved.
