What is the Intermittent Wiper Relay all about?
Intermittent wipers sweep once every few seconds, which is ideal for light rain and drizzle. A relay or small timer module controls the pause between sweeps.
Keep in mind:
- If the wipers work on the normal settings but not the intermittent one, the relay is a likely cause.
- A fault in the stalk switch or wiper motor can cause the same problem.
- In some cars the relay is combined with other functions in a larger control module.
How it's done:
The fuse, wiper switch and motor are tested. The relay or module is located and tested. A new unit is fitted. The wipers are tested on every speed and with the washer
Our recommendation:
Fix wipers before the rainy seasons. In Kenya the long rains run through March to May and the short rains from October to December. Replace worn blades at the same time.
What common symptoms indicate you may need to replace the Intermittent Wiper Relay?
- The intermittent setting does not work.
- The wipers do not pause, or pause for too long.
- The wipers work on high and low but not on intermittent.
- Clicking from the fuse box when you switch on the wipers.
How important is this service?
Moderately important. In light rain a working intermittent setting keeps your view clear, and heavy rain makes poor visibility dangerous.
