Why is the fan not blowing?
If everything checks out ok it is either the blower motor switch or blower motor is bad. It is best to check power going to blower motor with a test light.
Are you asking about the interior fan or the fan located on the radiator? At least 2 other things will prevent the radiator fan from operating: A bad sensor or a bad fan motor.~~~~ If you are asking about the interior fan then tell us if the fan has been working on all speeds or has it lost one or two speeds ... if it has then your resistor pack is bad (can be a tough repair on some cars) ~~~ if all speeds were working and now are not ... It's a fuse or relay
