Dropped it off tonight and hope to know something within the next couple of days.

Did you make sure to seal around the wire hole grommets UNDER the marker lights? This is usually where the water gets in and runs down the door columns and reaches the carpet. Just sealing around the marker light gaskets usually doesn't fix the problem. At least it didn't fix it for me.

I did, removed the grommet, cleaned and sealed with a bead around the hole and then after re-inserting the grommet.

Hello , you might also check the windshield itself especially if its been changed before and also ac evaporator drain is not clogged mostly for passenger side.

Just run it through the drain tube now and them.

We have a tool at my bodyshop that does the same thing.

It's called an air hose.

Take an air hose with a blower on it and pull the button. It'll blow whatever is clogging the line out.


Of course, mine doesn't cost 60 bucks so it probably doesn't work as well.... lol.

Might be a good idea to cut the regulator down to about 30 psi. The 120 psi from the air hose could easily split the sunroof drain hose or pop it loose from it's fittings

Hey 06, any updates?

I'm having the same issue. I've had at least one identifiable leak repaired as the windshield needed resealed.

I'm on my 3rd shop (Hummer dealer couldn't /didn't help) and a buddy's shop couldn't ID the leaks.

I've had the drains cleaned and was told at the time they were clogged. So I'm going to try sealing the gaskets.

I have an 03.

Lemme know. Thanks!
