Paragon,
According to Rodster's diagram from the service manual, I'm absolutely sure they left the duct out. All the air is being blown into the interior of the center console. I can feel the AC coming off the gaps of my gear selector.
When I removed the center console, I noticed that the rear AC vents were connected by this Y-shaped duct. But they were not connected to anything else. These installers didn't know what they were doing.
There are so many problems with the install. I've actually made a webpage for the installer so that they know exactly what went wrong. The sales guy was not the installer so he did not know what was going on. Here is the link to the page with all the problems in detail:

If you guys are looking for install in the So. Cal. area, send me a PM first before you go to the wrong place. Their prices on the equipment were the best though.
