How much does it cost to fix a 2012 GMC Savana 1500 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.

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 steps to diagnose the windshield wiper issue on a 2012 GMC Savana 1500?

To effectively diagnose windshield wiper issues on a 2012 GMC Savana 1500, start with a systematic approach that prioritizes simpler checks before delving into more complex diagnostics. Begin by inspecting the wiper motor, as a non-functioning motor is often the primary culprit behind wiper failures. If the wipers are completely unresponsive, this is a strong indicator of a motor issue. Next, examine the wiper switch, which is responsible for sending signals to the motor; if the switch is faulty, it may not communicate properly, leading to wiper inactivity. If the switch appears to be functioning, proceed to test the wiper module, as it is essential for relaying commands from the switch to the motor. Lastly, consider the wiper relays located within the fusebox; while these are less common sources of trouble, a malfunction here can disrupt the entire wiper system. By following this diagnostic order, you can efficiently identify and address the root cause of the windshield wiper problem, ensuring a smoother repair process.

What are the common problems that could cause the windshield wipers to stop working on a 2012 GMC Savana 1500?

When dealing with non-functioning windshield wipers on a 2012 GMC Savana 1500, it's essential to understand the common problems that could be at play. One of the first things to check is the fuse associated with the wiper system; a blown fuse can easily disrupt the power supply, rendering the wipers inoperable. If the fuse is intact, the next likely culprit could be a faulty wiper motor, which may require replacement if it fails to operate. Additionally, worn or damaged wiper blades can significantly affect performance, so inspecting and replacing them is a straightforward fix that can restore functionality. Another potential issue is the wiper linkage, which connects the motor to the wiper arms; if this linkage is broken or damaged, it will prevent the wipers from moving correctly. Lastly, a malfunctioning wiper switch can also lead to operational failures, and replacing this component can often resolve the issue. By systematically checking these common problems, you can effectively troubleshoot and restore your windshield wipers to working order.

How urgent is it to repair the non-functioning windshield wipers on a 2012 GMC Savana 1500?

Addressing the issue of non-functioning windshield wipers on your 2012 GMC Savana 1500 is not just a matter of convenience; it is a critical safety concern that requires immediate attention. When windshield wipers fail, visibility is severely compromised, especially during rain or snow, which can lead to dangerous driving conditions and increase the likelihood of accidents. Moreover, operating a vehicle without functional wipers may violate traffic laws in many jurisdictions, exposing you to fines or legal repercussions. Additionally, neglecting this repair can result in further damage to the wiper system or even the windshield itself, leading to more costly repairs down the line. Therefore, it is essential to prioritize the repair of your windshield wipers to ensure a safe driving experience, comply with legal standards, and avoid unnecessary expenses. Taking action now will not only enhance your safety but also contribute to a more comfortable and secure journey for you and your passengers.
