HVAC Fan Speed Setting 5 will not work

Ok guys here's what I've got.

Wifes 02 Grand Prix GT, fan speeds 1-4 didn't work, and speed 5 just stopped too, as I was coming home from getting the new resistor. So replaced the resistor anyways cause it obviously needed it (old one the PCB was cracked in half!). Now speeds 1-4 work fine, but no speed 5. Any idea what's up? I'm hoping it's not the ignition switch. I'm willing to be it is, but I'm holding out hope it's not.

Thanks.
 


I believe that the high speed has a separate feed and fuse, you might want to check that. Im not 100 percent sure but maybe.
 
Ok thanks I'll go through the fuses after I pick up the wife from work. (She can't drive my car cause it's a manual HA!)
 
Yes, the high speed has a separate fuse. So check that. But also could be a bad ignition switch.
