heater blower trouble
 

i have '85 w124. my blower for the heater/ac has stopped working. i have looked at chematics in haymes repair manual and am trying to trace the wires from the fan speed control to a blower resistor. i cannot find this resistor. does any body know where this is. also does anybody know the correct way to access the blower motor itself . i have the under dash and center console removed from the car.
