I have a 2002 40' diesel Monaco Diplomat and want to put a new dash blower motor in. The current one only works on high. How do I gain access to the motor? None of my manuals's show the location. Plus looking over the dash I am stumped as to how to remove the dash top or front or what have you. Thanks

Are you sure it's the motor? Could also be the control unit and they can burn out.

motor works on high only...could be a resister I guess

You answered your own question. If the motor is bad, it wont work. High is a separate circuit, from the lower speeds.

Also many lower speed circuits are protected by a separate fuse. Check the fuse and check the resistor pack.

Works on high only, 99% of the time means you need a resistor pack. The fan speed is controlled by resistors, when the pack goes bad only high speed works.

Almost sure it is the resistor. Simple fix for low $$$. Lots easier than the motor.

Now if somebody could tell him where it's at, he'll have it fixed in no time.

The resistor pack for the blower motor is located outside the firewall, you can access via the generator slide, it is above the AC/Heater enclosure mounted in a cutout so it is recessed, I believe it is held in with 2 screws.
