What is Intermittent Wiper Timing Reslay?
This is a useful feature that allows you to increase the speed of your windshield wipers when there’s a downpour. The intermittent wiper relay is also available to complement this feature.
Many vehicles come with intermittent wiper relays, which can gradually alter the speed of the wipers. The relay activates each time you operate the wipers. It allows you to change the speed of your wipers. When the wipers are running at high or low speeds, the motor will continue to run. The intermittent setting stops the wipers from stopping between every wipe. Relay acts as a switch, turning circuits on and off according to the driver’s preference. It controls the electrical current to the wiper motor. This type of control allows the driver the ability to adjust the speed according to the intensity and amount of the rain.
What are the Signs of Intermittent Wiper Failure?
It is extremely useful as long the windshield wipers system works properly. But, there is a risk of safety hazards if some components fail. The intermittent wiper relay is one of the most likely parts to fail.
The intermittent wiper relay, like any other relay in your vehicle, is designed to last for the lifetime of the vehicle. It can be damaged by the constant use and high temperatures it is exposed to and may stop functioning properly. This could cause the windshield wiper system to stop working properly and make it inoperable.
The following are some of the most frequent symptoms that indicate it’s time for a replacement of the intermittent wiper relay:
- – Inability of changing the speed of the windshield wipers
- – Windshield wipers not working
- – Wipers running at a constant speed or at a different rate than the chosen one
- – A hum when the wipers are on
Relays can fail completely or one circuit may be damaged, just like all electronic components. Your wiper relay could be defective if the high and low speed positions of the wipers work but not the intermittent function. A faulty relay can be identified by a combination of non-operating and working positions.
If the intermittent wiper relay stops working, it is usually because the wipers only operate at one speed. It is possible that the intermittent wiper relay has failed to respond, even though you have tried different settings.
