I salvaged a blower motor assembly from a portable room air conditioner and I am having trouble wiring it up. It may have a bad motor I don’t know for sure. I want to wire it to a standard 3 prong power cord.
Blue ( hard to read but looks like it is for switching
Red- High
Yellow- medium
White- low
2 black wires that diagram show going into the opposite side of the motor. I want to wire it for high.speed.
Any help would be appreciated.

Look for a nameplate on the motor. If you can identify the motor the wiring diagram may be available.

That was a good idea, I didn’t find the exact set up but close enough for me to figure it out. I wasn’t allowing for a missing capacitor.
