Question about 2000 GMC Safari
Sounds like the blower motor resistor is bad. These things go bad all the time. and for the switching modes there is a vacuum line that runs under the window in the engine compartment and runs by the alternator, its tiny and may take a few minutes to find. check first by the evaporator case and follow it by the alternator to the driverside of the throttle body. these too break and will not allow the heater mode changes. the blower motor resistor controls the fan speeds and the vacuum line allows which vent the air flow goes through.
