How are windshield wiper issues diagnosed?
Most often, windshield wiper blades will be noticed on an inspection, or noticed by a driver who is dissatisfied with the level of performance, or materials in their current windshield wipers. When a vehicle hits the mileage mark for a factory scheduled maintenance interval for windshield wiper replacement, they should be changed as soon as possible, but most times, they will not be, and a technician will take notice when the vehicle is in for the next oil change. Lastly, if the customer complains that the windshield wipers miss spots, move water around, or streak water, the windshield wiper blades will most likely be recommended for replacement sight unseen.
