What Causes Simultaneous Failure of Windshield Wipers and Turn Signals?

[PenelopeLee]

Here is a detailed explanation of the possible causes for simultaneous failure of windshield wipers and turn signals: Check Wiper Operation Inspect the wiper operation and check if the wiper arm exhibits uneven movement or missed spots. If any of the following three conditions occur, it indicates faulty wipers: first, irregular movement or abnormal jumping of the wiper; second, incomplete contact between the rubber blade and the windshield, leaving streaks; third, a water film or fine lines, haze, or linear residue remaining on the windshield after wiping. Pay Attention to the Arm Connection Check if the wiper arm is correctly connected to the wiper linkage. Some arms are secured to the linkage with screws, while others use a locking tab mechanism.
