There are many reasons why it does not work: its temperature control may be set too high; it may have lost all its refrigerant because of a leak in the system; its compressor pump may have stopped working; etc...
If you cannot see anything obviously "set wrong" the best advice anyone should give you is to call a licensed Heating, Ventilation and Air Conditioning (HVAC) technician to advise you and/or fix it for you.
On an auto temp system the blower motor resistor has failed and needs replaced.
Motor hasseized.
The blower is drawing to many amps. Have it checked. If that's not it. your blower motor is shorted out. Om the motor to the frame.
A blower motor shutting off with a battery charge light lit might mean that there is a problem with the power supply going to the blower motor. A bad battery or alternator could also be the cause for this.
Sounds like its getting hot and the thermal protection is shutting it down. Try cleaning it or oiling it.
Blower motor fuse is blown. Blower motor resistor burned out. Blower motor switch bad. Blower motor bad.
Blower motor: remove the glove box and you will see the blower motor and blower resistor.
usually the blower motor resistor pkg. located on or near the blower motor
If you are saying the blower motor will not work, then check the fuse. If the fuse is not blown, then it is possibly a defective Blower Motor Resistor Pack, blower motor, or blower motor speed control switch, in that order.If you are saying the blower motor will not work, then check the fuse.

It's close to the blower motor.
The blower motor fuse protects the blower motor electrical circuit. The blower motor relay operates only the high speed function of the blower motor. The blower motor speed resistor operates the lower speed functions of the blower motor.
Generally the blower motor resistor is found close to the blower motor. It relies on the blower motor to keep it cool.
