Replace the climate control/fan circuit fuse.
You may have a leak in the system. When the refrigerant level drops below a certain point the fan and compressor will not engage.
No. If your referring to the fan on switch on the thermostat. The answer is no only the indoor fan runs if the thermostat is properly wired.
Before you turn on a fan, the air is essentially hot because it is still and there is no circulation byconvection of the air currents. When you turn on the fan, it sparks a circulation where the hot air at the top flows to the opposite side of the room, and then eventually becomes cooler and more dense, falls to the floor, and is pushed back towards the fan by the incoming hot air. So, when you turn on the air, the fan is just cirulating hot air, not making it colder. The air only becomes cooler when it flows away from the fan.
Check the fan's fuse in the fuse box. it may be a bad one.
You could have a vacuum leak, a bad controller, a bad air door or an electrical problem.......
Either the fan is no good or the heat sensor in your radiator, that turns the fan on is not working!!
either a bad fan switch or a bad blower motor. Take it to a trusted mechanic.
first of all i hate to say an obvious answer but does the heater motor even turn. Does it blow air at all. The first thing i would check is if the fan motor is blowing any air at all. If not u need to put in a new heater fan motor. first of all i hate to say an obvious answer but does the heater motor even turn. Does it blow air at all.

Clockwise
Get a fan at the factory
check heater fan to see if it is working.
The fan will not turn on till your vehicle is at operating temperature. Check it again when the engine is hot.
