MY 3 speed heater blower motor only works on high speed in my 2003 Georgetown motorhome.
Is rheir any fix for this problem?

The speeds on the HVAC fan motor are created by a couple of resistors mounted on a small panel that usually is attached to the fan housing. It's identified by a plug with multiple wires for the different fan speeds. The resistors aren't the little ceramic cylinders on a piece of wire looking thing, but a coil of resistance wire that is in the air flow of the fan to cool them off. Remove the part and take it to an auto parts store and they can match it for you.

Is rheir any fix for this problem? that was it. Now how do I get to the blower motor in my georgetown motor home?

First look under the hood on the firewall, they are sometimes accessible from that side. If the heater box doesn't poke through the firewall, then you'll have to remove panels and look under the dashboard. Is the fan sound coming from in front of the passenger seat? That gives a clue on what area to start.

Thankyou I thought it was there. I here the sound in front of the passenger seat.
