Probably the blower motor resistor is shot.
Much of the Dash heating/AC system in our 1992 32-foot Winnebago Chieftain was supplied by SCS/Frigette of Forth Worth , Texas. (www.scsfigette.com) The blower motor resistor is accessed by opening the hood of the motorhome. The four-wire blower motor resistor connector is located on the front of the SCS evaporator assembly directly behind the passenger side headlights. The resistor is accessed by unscrewing the two phillips-head screws on either side of the blower motor connector and prying the resistor assembly out of the evaporator assembly with a regular screw driver.
open the hood and it's on passenger side under hood

Most likely and bad blower motor resistor.
You probably need a blower motor. Check the Hot electrical feed to the motor. If you have replaced the resistor block you know where the motor is located (just to the right) It is easy to replace and can be purchased everywhere, including a junk yard. Remember some Resistor Blocks fail because the motor is old and drawing to many amps.
