Run a 12 volt jumper lead to the fan motor connector from the battery or fuse box, if the fan runs replace the fan speed control module

heater valve to let the coolant into the heater core is not working the heater cluster in your dash that controls the heat might be bad. it also controls the fan and air conditioner
SOURCE: no low speed heater fan, only high speed works
BLOWER MOTOR RESISTOR IS BAD . HI SPEED IS DIRECT POWER BUT ALL OTHERS GO THROUGH RESISTOR

SOURCE: 2005 silverado heater fan not working
unplug the blower motor and test it for power and ground, find out which isnt working, if there is a failier at the socket you may have a bad blower speed control. If that socket passes you testes then it should be your blower motor.
SOURCE: need to find a fuse chart to tell which fuse to check, the numbers are 1 through 40
use a probe and check fuses to see if one is blown should be power on both sides of fuse if not it is blown repplace as needed
