Replaced blower motor & resistor - still not working :(

[rvac334]

1997 GMC Jimmy 4.3l engine. Ac/heat would blow intermit at differ speeds. Then just totally stopped. Checked 20amp fuse. No issue. Write ups said most likely resistor or motor. Replaced both. No change. Any suggestions? Relays? In-line fuses? Interior switch? Thanks for any tips

Check to see if you have power to the big wire, either orange ir red that runs to your relay
