Was working fine, all speeds , wired in aux fans for radiator , worked awhile then quit . Fues good , hot wired motor it runs , ck's the resister, it all looks good , diode is good . Relay changed , still no blower speeds or a/c clutch kick in .

Volts to switch, fuse good, resister looks good, blower does work when 12 volt jumper led to it. a/c clutch is good , it all worked , I hooked in aux fans for radiator, worked awhile then it quit . Relay changed also , could it be a fusable link?? Somewhere??
