How does the intermittent wiper relay system work?

This operation is completed thanks to the intermittent wiper relay; an electrical switch that sends a predetermined setting to the wiper module to power the wiper motor. When all of the components involved in the windshield wiper blades work correctly, the system is very convenient.

Why is my wiper blade motor not working?

Similar to the issue above, if you notice that your wiper blades are operating at a different speed or intermittent setting than you selected, it’s a good indication that the relay is damaged and needs to be replaced. This is also a symptom that you don’t want to avoid as it may cause the wiper blade motor to overheat and break prematurely.

What to do if your wiper module won’t turn on?

Wiper blades won’t turn on or off The wiper module’s primary job is to send a signal to the wiper motor which powers the wiper blades. Before it can control the speed or duration of the wiper blades, it must first tell the motor to turn them on or signal them to shut off.

What happens when a windshield wiper relay goes bad?

When the relay is faulty, the windshield wipers will only work at the same speed that the last relay signal was sent. In layman’s terms, if you had your windshield wipers on the slow speed the last time they were active, and you turn them on again under a different setting, the relay switch should send that updated information to the module.

How can I tell if my intermittent wiper relay is bad?

That the high speed — the least frequently used — selector still works suggests the tension has gone from the low and intermediate speed contacts. If they can be accessed and bent to create more tension this is a temporary fix at best; replace the switch. Having ascertained that the switch is good, test the wiring harness.

Why does my windshield wiper keep working intermittently?

If the problem is not in the switch, then there could be a bad relay in the circuit (if so equipped), loose fuse, bad ground, and/or the motor could have a bad (intermittent) connection on the armature.
