Use voltmeter or ohmmeter to check for a blown fuse. If you find one, replace it. Start car and see if the blower motor works. If fuse blows again, check for loose circuits.

The fuses in the fuse box under the glovebox protect components such as electrical sockets, displays and door modules. The central electrical unit is located behind the floor mat/side panel. The fuse box in the engine compartment provides space for several spare fuses.

Allow the blower to cool down, so that any metal components are safe to touch. Once the blower is cool, locate the reset button, which is usually red and located on the backside of the motor.
