Sparky

My 08 has a drain line, on the drivers side, that terminates in the spare tire storage area. It connects to a rubber elbow that goes to the outside. The elbow was blocked with residue and causing a leak in the storage area.

This is why you never buy a vehicle with a hole in the roof.

Wow....didn't know that Chevy had changed the routing of the drain tube. I think we the members, have erroneously mentioned down the A pillar to the front underside....if I'm not mistaking. Do you still have exit points in the front as well?

Unless additional drain lines have not be mentioned.

The 2 front drains go to the A pillars.
The 2 back drains go to that spot at the rear of the car.

At least, that's what I recall from a diagram that someone posted a while back

Thanks fireman....

I've always checked the fronts never knew/realized there are drains in the rear. Now I need to go look for them..........

Maybe tomorrow!!

Here it is Snoopy. Shows the drains on the right side. Just have to visualize the left side ones.

Thanks fireman.......

You know, I had the headliner out when I did the windscreen repair (performed several years ago according to the TSB that was provided by ChevyMgr) and I do not even recall those rear drains. Good thing I don't turn wrenches for a living.

Great diagram. I'm about to tackle my water issues tomorrow. Feel strongly it's my lines. they are either clogged or disconnected. I use a cup of bleach to keep my AC drain line clear on my house every year. Don't think I would risk it in the car though.

I see you have a 2006. Have you searched "butyl patch"? That's the more likely source of water.

I have a 2006, and had the butal patch leak (almost 2 gallons of water in the car). I fixed it with the sealer tape that they use to seal around the windows of a house, it's heavy duty and really sticky. never leaked another drop. took less than half hour to fix.
