Lexus GS400 windshield wipers do not turn off unless the car is powered off on Lexus GS400

Some Lexus GS400 owners report experiencing issues with their windshield wipers not turning off unless the car is powered off. This problem may stem from a malfunctioning wiper motor that requires replacement. Additionally, a faulty switch could be continuously signaling the wipers to remain on, leading to the same issue. Electrical problems within the wiper system, such as faulty connections or shorts, can also prevent the wipers from turning off. In some instances, a computer failure in the vehicle's system may be the culprit, necessitating a scan for trouble codes to identify the issue. To address these concerns, owners are advised to disconnect the battery as a quick fix, replace malfunctioning parts, check the wiper motor for faults, and inspect the wiper switch for proper functionality. Prompt resolution of these issues is important to ensure the wipers operate correctly.
