Chevrolet Impala driver side wiper arm repeatedly comes off and both wipers malfunction after snow storms on Chevrolet Impala

Some Chevrolet Impala owners report experiencing issues with the driver side wiper arm repeatedly coming off, often attributed to factors such as ice build-up, frozen components, or mechanical problems. Additionally, many owners notice both wipers malfunctioning after snow storms, which can result from ice accumulation, freezing of wiper components, or damage to the wiper blades. To prevent these issues, it is recommended that owners lift the wiper arms off the windshield when parking in snowy or icy conditions and clean any ice build-up off the wiper blades before driving. Troubleshooting may involve tightening the wiper arms and link arms to prevent dislodging, inspecting for bent or broken components like the "park tab" on the windshield wiper motor bracket, and ensuring proper removal and reinstallation of the wiper arms. Addressing these concerns promptly can help maintain wiper functionality during adverse weather conditions.
