most likely cause is one of three relays for the blower motor, usually located on the firewall under a plastic covering or near the battery If you do not use the blower motor very often like your car sits for a few weeks mositure gets in the blower motor and causes rusting which can cause your blower motor to lock up. Best suggestion is to run you air conditioning unit on high for about half an hour every once in a while.

The blower is a multi speed unit.

If the AC stopped blowing air on your 2003 Toyota Echo, the blower fuse could be to blame. If the fuse is fine, it might be the blower resistor that needs to be replaced.

Blown fuse, defective blower motor, or defective blower motor resistor pack.

On a 2010 Ford Fusion, the claimant control can stop the air-conditioning blower from blowing air.

It could be the blower itself as well. The first thing I would do is find the wattage of the blower (dc, I assume.) and connect the ground. Is there power to the unit?

Blown fuse, defective Blower Motor Resistor Pack, Defective Blower Motor, or Defective Blower Motor speed control switch.

It sounds as if you have either a power or ground problem at the motor.

Loose wire on blower motor? Broken bower motor resistor? Bad blower motor? Loose fuse in fuse holder? Bad fan switch?

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.

Your air conditioner blower may have stopped working because the blower motor isn't working. You can replace the blower or replace the air conditioner.

If there is an issue with your Ford Focus heater that blows intermittently it is a sign that the blower needs to be replaced or cleaned. A certified mechanic can do a diagnostic check to verify and make the necessary repairs.

There is an electrical short to ground in the fan switch or in the blower motor itself.

If the heater is blowing the fuse when the blower is turned on, I would suspect the blower motor is defective or locked up. If the A/C is blowing a fuse, suspect a bad clutch, or locked up compressor.

Maybe you are referring to a whistle blower. It might be an informant, the one who exposes wrongdoings.

Bad Blower motor fuse Bad blower motor resistor Bad blower motor Bad switch Evaporator plugged- not allowing air flow

the blower motor should be either on the passenger firewall or in the passenger floorboard below the dash
