If the fuse for a power window system is blown, which reason would NOT cause it?

A blown fuse in a power window system typically occurs when there is an excessive current flowing through the circuit. Such excessive current can be caused by conditions like a short circuit or a motor issue.

The scenario in which the motor circuit is open, represented by the binding window track or other obstructions, does not result in increased current flow. Instead, an open circuit would result in no current flowing at all, which would not cause the fuse to blow.

Conversely, a shorted wire to ground or a short in the motor would create a direct path for electrical current to flow excessively, leading to a blown fuse. Therefore, while options that indicate short circuits or mechanical binding can lead to higher current draw and potentially blow the fuse, an open circuit does not have the same effect and is the reason that would not cause a blown fuse.
