Rear a/c not working

The rear a/c on my 2000 quit working. The vents blow hot air; however, the front a/c works just fine. Any ideas on what I can check to fix this problem? Temperatures soaring into the 90s, kids are definitely NOT happy!!

I'd check the damper that diverts the air between the heater core and the evaporator coil.

Where is this damper located ? I have the exact same issue !!

Where would you look for that ?

I think there is only one ac compressor, so is this in the back ?

Thanks !

There is only one compressor. The compressor is in the engine compartment. The evaporator coil, heater core, and blower are all located on the passenger interior rear panel.
