Front a/c blower noise and rear a/c blower not working

Hello,
I am having problems with the a/c in my 1999 Astro. The blower fan sounds as if the bearings are going bad as the sound increases when the switch is moved from low to high speed and into max a/c. Air is still coming out of the vents.

But the rear fan seemed to quit altogether, no sound or air coming out of the vents. Where is the fan located for the rear a/c? I can't find any information and any help troubleshooting is much appreciated.
I have found solutions for replacing the front blower fan but not the rear fan.
