How much does it cost to fix a Mitsubishi Outlander 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.

Troubleshooting Non-Functional Windshield Wipers in a Mitsubishi Outlander

When troubleshooting non-functional windshield wipers in a Mitsubishi Outlander, it's essential to adopt a systematic diagnostic approach. Start by checking the wiper motor, as a complete failure of the wipers often points to this component. If the motor appears operational, the next step is to inspect the wiper switch, which can malfunction and cause erratic behavior, such as wipers that activate unexpectedly or fail to stop. If only one wiper is not functioning, examine the wiper system for potential issues, as this could indicate a problem with the linkage or the wiper arm itself. Pay attention to any unusual symptoms, such as decreased wiper speed or strange noises, which may suggest a deeper motor issue. Additionally, if the washer function is compromised, it could signal problems with the wiper switch input circuits or the ETACS-ECU. By following this methodical approach, you can effectively diagnose and address the issue, ensuring your windshield wipers operate smoothly and reliably. If the problem persists despite your efforts, seeking professional assistance may be the best course of action.

What to Check When Windshield Wipers Aren't Working on a Mitsubishi Outlander?

When your Mitsubishi Outlander's windshield wipers fail to operate, it's essential to systematically diagnose the issue to avoid unnecessary repairs. Start by examining the wiper motor, as a malfunction here is often the primary culprit behind wiper failure. If the motor appears functional, the next step is to inspect the wiper switch, which can also lead to operational problems if faulty. Additionally, ensure that the wiper blades are free from obstructions such as ice or debris, as these can hinder their movement. It's also wise to check the windshield wiper linkage and arm splines for any signs of damage, particularly if the rubber edges have frozen. Lastly, don't overlook the windshield washer system; clogged nozzles, leaking hoses, or blown fuses can all contribute to wiper issues. By methodically addressing these common problems, you can effectively troubleshoot and potentially resolve the malfunction without needing professional assistance.

Why Are the Windshield Wipers Not Working on a Mitsubishi Outlander?

When your Mitsubishi Outlander's windshield wipers fail to operate, it’s crucial to address the issue without delay. Neglecting malfunctioning wipers can lead to dangerous driving conditions, particularly in inclement weather, where visibility is paramount. Common culprits include a faulty wiper motor or switch, which can prevent the wipers from functioning altogether. Additionally, if the wipers are activated while frozen to the windshield, it can cause damage to the wiper linkage or arm, leading to more extensive repairs. It's also essential to inspect the wiring harness for any loose or corroded connections, as these can disrupt the power supply to the wipers. If the wipers are not returning to their park position, this may indicate a problem with the motor's internal switch. By diagnosing and addressing these issues promptly, you not only ensure your safety on the road but also prevent further damage to your vehicle, making it a vital DIY task for any Mitsubishi Outlander owner.
