2001 Grand Caravan - Rear blower resistor

Where is the REAR blower motor resistor pack located on an 01 GC? I've replaced the front plenty of times, but I can't figure out where the rear module is.

Thanks!

Don't know about the 2001, but my 2000 book says the resistor pack for the rear blower motor is internal to the blower motor and if it goes out, the motor needs to be changed. Maybe a salvage yard has one.
