Water intrusion in rear cargo area?

[FW_Z71Burb]

Happy Saturday and anniversary of D-Day y’all
The burb started to develop a STANK the last few days. Thought it was a dirty diaper left behind somewhere under the 2nd row but that ain’t it. Finally pulled up the rear cargo mat and the right side of the rear cargo area is moist.

We’ve gotten a lot of rain in Texas but I don’t see any signs of water intrusion. Weatherstripping on the rear hatch lols good. Is this a typical area for water intrusion? Does the rear AC on this side leak or condense?

Thanks in advance

Umm. I painted the sail panels on both Suburbans, and one had some missing wheatherstripping. I put some rtv around it.

Maybe that's where the water may coming in from? Let me see if I can find some photos?

Here's the photo. Driver's side sail panel. I can't remember if I had any water getting inside on this suburban or not prior to me noticing this?

I would pull the cover(s) and look in the a/c system.

Your rear AC system is behind that side panel. I will bet money that the drain tube to get rid of condensation is stopped up, and it is overflowing from the blower housing. Look under the chassis in that area for a rubber tube hanging down, if if you can find it, clear it with a piece of wire to try and get water flowing again.

I've had that happen with my pickup truck, but that was the front, and that drain tube is on the passenger side firewall and easier to get to.

@stutaeng Thank you will check it out. Nothing looked out of the ordinary. Raining again tonight so will see if there’s any intrusion in the morning

That makes a lot of sense.. we’ve been using the AC more lately. apppreciate that info will check her out

Fair warning. Do not, I repeat, do not look straight up at the drain tube when you use a flexible piece of whatever and stick it in the drain tube opening. You will get a face full of water as it releases and comes running out.
