Rear blower motor resistor location

i have a 2001 dodge grand caravan with rear a/c and heat(auxillary) the blower motor stopped working. i would like to know where the resistor for that is located?

In the same housing that the fan is, in general.

If the motor doesn’t even work on full high then there may be something else wrong besides the resistors. They are bypassed in the high mode. Be sure to check your fuses first.
