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.
When diagnosing a windshield wiper issue in a 2015 BMW 535d xDrive, it's essential to adopt a systematic approach that begins with the most straightforward checks before delving into more complex diagnostics. Start by examining the condition of the wiper blades; if they are streaking or not moving smoothly, replacing them may resolve the issue. Next, observe the wiper's resting position when turned off; any abnormal height or failure to return to the base position could indicate a malfunction in the wiper system. Ensure the windshield wiper sprayer is functioning correctly, as a blockage or failure here can also affect wiper performance. If these initial checks do not reveal the problem, inspect the Junction Box Electronics (JBE) for faults, as this component controls both the wiper and washer functions. Look for any wiring or connector issues, particularly at the wiper stalk, which could disrupt the electrical supply. Testing the voltage at specific connectors can help confirm whether the system is receiving adequate power. If the wipers behave erratically, consider the possibility of a defective relay or software error, which can be diagnosed by accessing the vehicle's fault memory. Lastly, don't overlook the rear windshield wiper; ensuring it is in good condition is crucial for overall visibility and safety. By following this structured diagnostic approach, you can effectively identify and address any issues with the windshield wiper system in your BMW.
Repairing non-functioning windshield wipers on your 2015 BMW 535d xDrive should be treated with urgency, as failing to do so can significantly compromise your safety while driving. Windshield wipers are essential for maintaining visibility during rain or adverse weather conditions, and any malfunction can lead to dangerous driving situations. If your wipers are inactive when switched on, it may indicate a failed wiper motor, while slow or uneven movement can suggest underlying issues that require immediate attention. Ignoring these symptoms not only increases the risk of accidents but can also lead to more extensive and costly repairs down the line. Therefore, addressing wiper issues promptly is crucial to ensure a safe driving experience and to prevent further damage to your vehicle's electrical system.
