Question about 2002 Chevrolet Silverado 1500
3 WEEKS AGO STARTED TRUCK FAN WOULD NOT WORK, THE NEXT DAY STARTED AND WORKED PERFECT TILL TODAY.
Could be the blower motor, or the resistor, or a bad connection in the harness. Someone would need to check for power and ground at the motor first.

I had this same problem. What I did to resolve it was to slap the underside of the fan housing (in the passenger floor board) until the blower came back on. The fan/blower housing is that big black box right under the glove compartment. I know that sounds stupid, but I think there is a plug above the blower that is not making a good connection, so when I slapped it upwards it reseated itself and the blower came back on.

Check the relais module located inside under the rh side of the heather box you can see the connector most of them need to be replaced as they burn out you may need to replace the blower motor as well,high amp draw caused by faulty bearings will overload the blower motor controller
