or bent components that may be preventing the wiper from functioning properly. Ensure that the wiper arm is securely attached to the motor shaft and that there are no loose or missing components.

Inspect the Fuse

it may need to be replaced.

Inspect the Wiring and Connectors

as well as loose or corroded connectors. Repair or replace any damaged components as necessary.

Reset the Rear Wiper System

resetting the rear wiper system can resolve issues with its operation. Consult your vehicle’s owner’s manual for instructions on how to perform a system reset. This may involve a specific sequence of actions or using a diagnostic tool to initiate the reset procedure.
