To start with, one of the known Part#s for the blower motor is PM105. One of the known applications is a 1994 or 1995 Chevy pickup truck.
Before doing the work of replacing the blower motor, do check to see if the blower motor rheostat is OK. I'm not sure exactly where that is on your coach, on mine it's on the right side in front of the firewall on top of the heater box. I'm sending you a private message with more info about this.
The blower motor is just behind the front of the dash at about the top of the steps. The dash must be opened up and taken apart to the point that you are able to remove the blower motor.
If you remove the screws holding the dash air vents and pull the dash air vents out of the dash a little, you should find screws in there that hold the top of the dash down. Once you are able to lift the dash top up a bit, you should begin to find other screws that need to be removed.
It's slow, tedious work requiring considerable patience.
Your wood box in the middle that holds the center of the dash has to be removed. You'll have to find all the screws holding it in place. One trick about this is the dashboard vinyl can 'weld' itself to the lacquer on the wood box, making the box impossible to remove. If you carefully insert a thin plastic blade between the vinyl and the wood, you can free the vinyl to allow the box to slip out.
Once the dashboard is opened up, replacing the blower motor is a very simple job. Make sure the blower works before putting the dash back together. If it doesn't, check the power wire to the motor. If it is dead, look around inside that dash for a Bosch relay that may be burnt out. If you have to replace that relay, now might be a great time to relocate it somewhere else outside the dash for future servicing.
