Common Reasons for a Windshield Wiper Not Working on Passenger Side

A malfunctioning switch, damaged motor, or problems with the windshield wiper arm linkage are all common reasons for why a windshield wiper may not be working on the passenger side. Before doing any further troubleshooting or replacing parts, it is important to properly diagnose the problem at hand.

Diagnosing the Problem

The first step in diagnosing why one of your windshield wipers is not working on the passenger side is to do some preliminary troubleshooting. This includes checking whether the switch responsible for controlling your wipers is turned on and whether there are any visible obstructions that could be preventing one of your wipers from functioning properly. If neither of these appear to be an issue, then it is likely that there is something wrong with either the motor or windscreen wiper arm linkage.

Taking off Windshield Wiper Arm Assembly

In order to inspect both the motor and the wiper arm linkage, you will need to take off your windshield wiper arm assembly. To do this, you will need to carefully remove both your driver and passenger side wipers from their respective arms by loosening their screws with a screwdriver. Once removed, you can then take off your entire windshield wiper arm assembly by unscrewing its mounting bolts using a socket wrench.

Troubleshooting Electrical Issues

Once you have taken off your windshield wiper arm assembly, you can now begin troubleshooting any potential electrical issues that may be preventing one of your wipers from functioning properly. The first thing you should do is check your vehicle’s fuse box for any blown fuses that may be causing an electrical malfunction in your vehicle’s windscreen wiper system. If everything appears normal here, then you should next test all of the connectors and cables connected to your vehicle’s windscreen wiper system to ensure that they are securely connected and free from any damage or corrosion.

Replacing The Motor

If after fully inspecting both your motor and windscreen wiper arm linkage you find that either one needs replacing, then it will be necessary for you to purchase a replacement part before proceeding with installation. The exact type of motor or linkage part needed will depend on what type of vehicle you have so it is important to consult with a qualified mechanic before making any purchases. Once you have acquired the new part(s) needed for installation, follow all instructions provided by either a qualified mechanic or manufacturer’s guidebook in order to properly install them without causing further damage to yourself or your vehicle.

Problems With Windshield Wiper Arm Linkage

If after inspecting both the motor and windscreen wiper arm linkage it appears as if there are problems with either one of them then it will be necessary for you to replace whichever faulty part(s) are causing issues in order for proper operation of both sides of your windscreen wipers again. Inspect linkages and actuators carefully in order to determine where exactly any issue lies before making any purchases as this can help save time and money when fixing such an issue. Once identified, replace faulty part(s) according to manufacturer’s instructions in order ensure proper functionality once again before returning car back onto roadways safely

Locate the Switch

When it comes to figuring out why one windshield wiper isnt working on the passenger side, it is important to locate the switch first. To locate the switch, start by inspecting the dashboard for a small box with an electrical cord attached to it. This will be the switch that controls the operation of the windshield wipers. Once you have located it, you will need to remove and replace it with a new one.

Remove and Replace Old Switch

To remove and replace the old switch, begin by disconnecting the wires from the old switch and removing it from its mounting bracket. Then, take the new switch and connect all of the wires according to their color coding or diagram. Finally, mount it in place and secure with screws or bolts as necessary. Once that is done, test out your new windshield wiper switch by turning on your car and activating your wipers. If everything is working properly, then you can move on to preventing future issues with your wipers.

Check Wipers Regularly

Regularly checking your windshield wipers can help you identify potential problems before they become major issues. When checking your wipers, be sure to look for any signs of wear or damage such as cracks in the rubber blades or metal corrosion on exposed parts of the wiper arms. Additionally, make sure that all connections are secure and that there are no missing parts or pieces that could interfere with operation of the wipers. If any issues are found during this inspection process, then they should be addressed immediately before trying out other solutions or replacement parts for your windshield wiper system.

Use Quality Parts During Replacement

Finally, when replacing any part of your windshield wiper system including switches, blades or arms make sure to use quality parts from reputable sources whenever possible. Low quality parts may not last long under normal conditions and could lead to further damage down the line if not replaced correctly or quickly enough after being identified as faulty. Additionally, if you do decide to perform any repairs yourself make sure that you understand all safety precautions and follow them closely in order to avoid any injury while working on your vehicles systems
