How much does it cost to fix a 2017 Lincoln MKZ windshield wipers aren't working?

Common Repairs

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.

Inability to control the windshield wipers comes in several forms, and they are all indicative of windshield wiper switch failure. The windshield wipers may not work in all settings, may not turn on when requested, may not move to their parked position when turning off, or the washer pumps may or may not run at random. This is a general list of symptoms, but failure of anything the windshield wiper switch controls will indicate the need for testing the windshield wiper and washer switch.

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.

What are the initial diagnostic steps to take when the windshield wipers on a 2017 Lincoln MKZ aren't working?

When faced with non-functioning windshield wipers on your 2017 Lincoln MKZ, it's crucial to adopt a systematic diagnostic approach. Start by checking the windshield wiper fuse, as a blown fuse is often the simplest and quickest fix. If the fuse is intact, move on to inspecting the wiper motor to ensure it is receiving power and operating correctly. Next, examine the wiper switch, which controls the wipers; a malfunctioning switch can disrupt the entire system. Additionally, look for any obstructions that may be blocking the wiper blades, as debris can hinder their movement. Finally, assess the condition of the wiper blades themselves; worn or damaged blades can significantly impact performance. By following these steps, you can effectively diagnose and address the issue with your windshield wipers, ensuring a safer driving experience.

What are the common causes for windshield wipers not working on a 2017 Lincoln MKZ?

When dealing with windshield wipers that are not functioning on a 2017 Lincoln MKZ, it's essential to understand the common problems that could be at play. One of the first things to check is the fuse; a blown fuse in the vehicle's fuse box can easily disrupt the wiper's operation, and replacing it is a straightforward fix. If the fuse is intact, the next likely culprit could be the wiper motor itself. A malfunctioning motor may require replacement to restore functionality. Additionally, worn-out wiper blades can significantly affect performance, so inspecting and replacing them if necessary is a simple yet effective solution. Another potential issue is the linkage that connects the wiper motor to the wiper arms; if this linkage is broken or disconnected, it will prevent the wipers from moving. Lastly, consider the wiper control switch, as a faulty switch can also hinder operation. By systematically checking these common issues, you can effectively troubleshoot and resolve the problem with your windshield wipers.

How urgent is it to repair the non-functioning windshield wipers on a 2017 Lincoln MKZ?

When dealing with non-functioning windshield wipers on a 2017 Lincoln MKZ, the urgency of repair cannot be overstated. First and foremost, safety is paramount; without effective wipers, visibility during rain or snow is compromised, significantly increasing the risk of accidents. Additionally, many jurisdictions enforce laws requiring functional windshield wipers, and driving without them could result in fines or legal repercussions. Beyond immediate safety and legal concerns, delaying repairs can lead to further damage to the wiper system or even the windshield itself, which may escalate repair costs. Lastly, functioning wipers contribute to a more comfortable driving experience, allowing you to focus on the road without distraction. Therefore, addressing this issue promptly is essential for your safety, compliance with the law, and overall vehicle maintenance.
