I discovered an intriguing little hole and I wanna know what I can put inside it

Never know what you'll find in a Turnpike ditch

So are you telling me the squeaky squealing I occasionally hear from my blower fan is just a lube job fix? I ordered a replacement fan without looking at it, assuming a bearing is bad.

Air hose attachment for CPAP machine!

Nothing supposed to be directly behind that fitting, that's where the air filter will go.

Pete, it's taken me five minutes to stop crying and laughing and get the tears out of my eyes, thanks man! LOL

Honestly dub, that looks like an add on...I don’t think mine has that. I think, and bear with me im speculating, since its right above the filter access door that you dont have, the po may have had an odor in her box , so instead of gm doing the right thing and adding the door and fliter (may also be prior to door and filter being available.... years ago I remember guys on the truck forums making their own doors out of a piece if metal) and they used it as a anti box stink spray port.... no im not gonna look at mine...

Lubricating it may be more of a "patch" than a "fix". In my mind, if it's squeaking, it's already worn. Mine would squeak worse when I'd accelerate which tells me it had excessive lateral slack from wear. Replacing it is the sure fix. But, I don't have much faith in aftermarket motors so I'd get an OEM one and they are $100+. I found a new OEM motor by itself for under $30 and I'd just have to swap my blower cage onto it. I probably should've bought it but it's sold now. I just cleaned and lubed mine since it was a quick and easy fix, even if it's not permanent. If the squeaking comes back, I'll just get a new motor or motor/blower assembly then. For now, this cost me nothing but time so it was worth the shot. I have other unexpected expenses at the moment that are of much higher priority than a mildly chirping blower motor.

1000% sure. I'd be highly concerned if there were some monkeys dumb enough to route an antenna wire through the HVAC assembly working on my Tahoe at some point.

The original owner was a lawyer or business man of some sort so he probably had all service performed at a dealership. This is probably a port that's installed as part of a commercial-grade cleaning system for the evaporator core. I haven't been out to the shop to investigate any further and I won't until I get the cabin air filter retrofit kit.

Hehe ...layer.....stinky box.... port hole....hehe
