How to troubleshoot a blower motor that is inoperative on 2003 Mazda Protege?

If the heater blower is inoperative, check the heater circuit breaker above the under-dash fuse box (early models) or the under-dash fuse (later models). If tripped or blown, check for shorts at the blower connector, test voltage and fan speeds, then replace the blower or resistor assembly or repair harness.
