What are the common reasons for a passenger side wiper not working?

The most common reasons for a passenger side wiper not functioning include faulty wiper motors, broken wiper linkage, or a blown fuse. If the driver’s side wiper is working fine, the issue is likely isolated to the passenger side. Checking the fuses should be your first step, as this can be a simple and quick fix.

Another reason could be a problem with the wiper arm itself. It might have come loose and is not making proper contact with the windshield, or it may be broken. Situations like these can often be observed with a visual inspection to see if the wiper arm is securely attached and functioning properly.

How can I diagnose the issue with the passenger side wiper?

To diagnose the issue, start by checking the wiper motor’s functionality. You can do this by activating the windshield wipers and observing if there’s any movement on the passenger side. If there’s no movement, it’s likely an electrical problem or a mechanical failure, such as a broken linkage.

Next, inspect the fuse related to the wiper system. Consult your vehicle’s manual to locate it, and use a multimeter to test if the fuse is blown. If the fuse is intact, continue with a visual check of the wiper arm and linkage for any visible signs of damage or detachment.

Could a blown fuse cause the passenger side wiper to stop working?

Yes, a blown fuse can be one of the primary reasons why the passenger side wiper is not functioning. Fuses act as protective devices in your vehicle’s electrical system, and if one blows, it can interrupt the power supply to the wiper motor or specific components of the wiper system. If the driver’s side wiper is working, yet the passenger side is not, it is crucial to check the fuses first.

If you find a blown fuse, replacing it is relatively straightforward. However, if the new fuse blows shortly after replacement, it could indicate a more serious underlying electrical issue, necessitating professional assistance. Regular checks of your vehicle’s fuse box can prevent sudden wiper failures in the future.

What should I do if the wiper arm is loose?

If you notice that the wiper arm is loose, the first step is to turn off the wiper system to prevent any damage.
