Scion has many merits, but problems arise after the mirror switch parts have been used for a long period. A mirror switch is responsible for allowing the car occupant to control the mirror motor and move it to their desired preference. Signs of bad window switch parts include: no mirror movement, clicking noise coming from the mirror motor, and mirrors adjusting up and down but not left to right. There are plenty of inexpensive and quality Scion parts on our site. Consumers can get great Scion parts and services online 24 hours a day and 7 days a week.
