So as not to resurrect some years-old thread (of which I've read them all and learned a lot), I'll just ask this one question: exactly where at the bottom of the body would I find the drain/weep hole for the sunroof's rear drain? And is it located where I'll have to remove the running boards to get to it? (Hint: I won't mind a yes answer to that last question - I'd love to lose those things. ;))

My theory is that gravity being what gravity is, I should have a better chance at dislodging any junk that's stopping up the drain line(s) by coming up from the bottom. And as opposed to the Miata I used to own which required me to clean the drains from the top down, I can get under this vehicle with little effort. I just need to find the holes.

I poked around down there using the attached drawing that someone else was kind enough to post a few years ago but can't find where the drain goes from the bottom point of B pillar where the drawing shows it to be to the bottom of the truck.

And to paraphrase J J Cale, momma won't allow no wet seatbelts in this truck.

Many thanks in advance.

Edit: I guess I should attach the drawing.

I'm not aware of any sunroof drains in the B-pillar.

While I have never needed to clean them on my '08 Burb I did have to clean them on my 2000 Esky and they ran down the A-pillar and dumped out at the back of the front wheel wells.

Hmmm... thanks. I read about the A pillar as well in those other threads but got the distinct impression there were four drains - one for each corner of the sunroof and the rear two drained through the B pillars. Guess I read it wrong.

But the leak has gone away at least for now after I tightened the luggage rack screws a bit. Hopefully that takes care of things.

My neighbors NBS Denali had a leaky B pillar. He was unaware of it until he jumped in the back seat so his son could put some miles on the truck for practice.

He pulled the seatbelt on the d/s pass seat pretty hard and it unleashed a soup of moldy, curd all over his shirt. Within 15 min he googled a GMC dealer and traded it in on a ‘20 AT4 double cab while on vacation.

My suggestion, give the belt a good hard pull with someone holding a towel over the assembly if you suspect there’s water in there.

Wouldn't the rear seat belts be attached to the C-pillar?

Yes, ty C pillar. Would that make it a door seal leak?
