Assuming you have manual heater controls...
The hot wire is pink with white. this is power from the blower relay. this is a ground side controlled system meaning that the speed switch controls the path to ground for the blower motor.
If the switch is bad or you see power on both wires at the blower motor with the connector plugged in than there is a ground issue.
if you ground the orange with black wire and the blower still does not work than the blower is bad.
