Why does passenger wiper work and not the driver side?

If the passenger side wiper works but the driver side does not, it could be due to several reasons. Common issues include a blown fuse specifically for the driver side wiper motor, a malfunctioning wiper motor, or a problem with the linkage or arm that connects the motor to the driver side wiper. Additionally, there may be an issue with the wiper switch or wiring that affects only the driver side. Checking these components can help identify the root cause.
