Left windshield wiper not working is a common issue faced by drivers in a variety of vehicles. The most common cause of this issue is a faulty or worn out wiper motor, which is responsible for powering the left windshield wiper. Other possible causes include broken or loose wiring, a broken linkage, or a defective wiper arm. Diagnosing the cause of the problem requires inspecting the wiper motor, wiring, linkage and arm, as well as checking for any electrical faults in the system. Once the cause has been identified, it can be repaired by replacing faulty components and/or tightening any loose connections. In some cases, it may be necessary to replace the entire left windshield wiper assembly if it cannot be repaired.

Common Causes of Left Windshield Wiper Not Working

When your left windshield wiper is not working properly, it can be extremely frustrating. There are several common causes of this issue that you should be aware of.
