My Heater/AC fan just stopped today. How can I determine if it is a fuse, fan switch or blower?

Start with the fuse. If ok, get a test light and find the blower motor (under dash pass side) Check for power and ground at the motor with selector in all positions. If nothing test for power at the fan speed resistor (next to blower in the HVAC plenum)
