Part: Windshield wipers

This video tutorial explains step by step how to diagnose the operation of the front windshield wiper system, using a diagnostic tool connected to the vehicle via the OBD port. If nothing happens when you activate the switch, first check the fuse by locating it in the fuse box and replacing it if necessary. Next, check the pump that pushes water onto the windshield, ensuring that the inlet and outlet hoses are not clogged.
