The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.
A failed windshield wiper motor will do one of two things in the event of failure. First, it can intermittently work, meaning when the wiper switch is turned on, the windshield wipers may activate, and run for a random amount of time. This may happen at random, or change with a bump. Lastly, the windshield wipers could show no signs of activity, indicating motor failure.
The moment water touches the windshield, you know if you need new windshield wiper blades. If your wiper blades are torn, cracked, hard, or brittle, it is time for replacement. Wipers should also be replaced if the wiper blades only smear water around, seem to make a mess, streak the windshield, and miss large patches. If you are unhappy with the current wiper blades on your vehicle, this is a very economical change to make.
Windshield wiper arms will be replaced mainly for aesthetic reasons or damage. If the windshield arms become bent or rusted, the windshield wipers may not contact the windshield at the proper angle, or there may be no contact at all. Also, the sun will take a toll on these parts after years of use, and fading or clear coat peeling will result, not to mention rust.
To effectively diagnose a windshield wiper issue in a 2013 BMW 320i, start with a systematic approach that prioritizes simpler checks before moving on to more complex diagnostics. Begin by inspecting the wiper blades for any visible signs of wear or damage, as this is often the easiest fix. Next, test the wiper motor by unplugging it and checking for 12 VDC at the wire connector while the ignition is on and the wiper switch is activated; this will confirm whether the motor is receiving power. If the motor is functional, proceed to examine the wiper relay for faults, as a malfunctioning relay can disrupt the wiper's operation. Additionally, inspect the wiper linkage for any damage or misalignment, ensuring it is securely connected to the wiper transmission shaft. It's also crucial to check for any electrical issues, such as loose connections or damaged wires, that could affect the wiper system. Finally, observe the behavior of the wipers when activated, noting any unusual movements or sounds that may indicate specific problems. If these steps do not resolve the issue, consulting a professional mechanic with expertise in BMW vehicles is advisable for a thorough inspection and repair. This methodical approach not only helps in identifying the problem efficiently but also saves time and resources in the DIY process.
Addressing the issue of non-functioning windshield wipers on your 2013 BMW 320i is not just a matter of convenience; it is a critical safety concern that requires immediate attention. When wipers fail, visibility during rain or snow is severely compromised, increasing the risk of accidents. Moreover, many common problems, such as worn-out blades or loose components, can be resolved quickly and affordably through DIY repairs, making it a manageable task for most car owners. Ignoring these symptoms can lead to more severe issues, such as motor failure or damage to the wiper system, which could result in costly repairs down the line. By taking action now, you not only ensure your wipers are ready for use when needed but also prevent further complications that could jeopardize your safety on the road. Therefore, it is essential to prioritize the repair of your windshield wipers to maintain optimal driving conditions and avoid unnecessary risks.
