2009 LTZ Rear AC Ducting?

[jared999]

Hey all!

I was replacing my headliner and notice there isn't any ducting going from the rear AC unit to anything.
Looks like I'm missing some type of ducting that goes from that blower to the roof. The red square on the headliner photo is where the AC would enter the headliner.
So that leads me to two questions
I'll need to go to a yard, but I need to make sure I'm targeting the correct optioned vehicle and not driving around wasting time.

Q: Can I use the VIN of a Tahoe / Yukon to find if it has rear AC?
Q: Do all LTZ and Denali's have the rear AC?

I think you will need the RPO to confirm for 100%, although as far as I know all LTZ and Denalis should have rear AC as std.

Interesting enough, my stripped down SSV has rear air/heat with air flowing from the roof. Any history on the truck - perhaps P/O repaired/replaced headliner at some point and half-assed it?
