    When my son bought his truck the fan only worked on setting 3 and 4, I know that’s probably the blower motor resistor. Now it won’t work at all. Would it be the same fix or something else??

    If the blower fan is bad, it can blow both the resistor and sometimes even the fuse depending on the car model. Therefore, in my ears it sounds like the blower fan first blew the resistor and probably the fuse. In this case, it would be required to replace the blower fan + resistor + fuse. However, more in-depth troubleshooting is preferred.

    2003 silverado. It could be the fan is bad. I come from a old school and would start with the heater control fan switch then work from there did the fuse blow? With the heat control on wiggle the fan control switch a little back and forth from low speed to high and listen if you can hear anything happening.
