An unlikely, but possible, cause is a bad thermostat. Try turning the Fan switch to the "On" position to see if the blower comes on. Watch the video. If the blower operates in the "On" position and does not operate when the air conditioner is running, you may have a bad thermostat.

How do I know if my AC blower motor is bad?

Signs and Symptoms of a Bad AC Fan Motor

1. The fan won't start even though the AC is on.
2. The fan won't stop, even when you shut the AC off.
3. The fan turns on, yet the blades are rotating very slowly.
4. There's a rattling noise coming from the condenser unit when the fan is turned on.

Does AC blower have a fuse?

Because of the volume of air that is moved by the blower fan, the motor may pull up to 20 amps or more at high speed. To protect the blower motor power circuit, a 20-, 25- or 30-amp fuse is usually located in the fuse panel under the dash.

Where is the AC blower motor fuse located?

How do I know if my AC fuse is blown?
