When I started fixing the blower motor, I only had one fan speed.
I replaced all of the components in the blower motor circuit (blower motor, relay, resister, and switch)
Now I have nothing the fuse is good. I can get the blower to work with direct power to the switch all three speeds and a fourth (the off position). I’m lost
