Frequently Asked Questions
Is it safe to drive without wipers?
No. Driving without functioning wipers in rain, snow, or any conditions requiring windshield clearing is extremely dangerous and illegal. Do not drive until wipers are repaired.
Why are my wipers stuck in the up position?
The wiper motor has a park switch that returns the wipers to the rest position. If this switch fails, the motor stops at whatever position it was in when turned off.
What is the wiper linkage?
The wiper linkage is a set of metal arms that connect the wiper motor to both wiper arms. If a pivot point or connecting rod breaks, the motor can run but the wipers will not move.
