How does the intermittent wiper timer relay work?
The timer is activated from the wiper switch ‘intermittent’ position and closes the relay once every 5 seconds, sending power to the wiper motor. Incorporates an output for supplying +12V to the wiper motor park switch which shorts the motor at the end of the wipe cycle, bringing the blades to an immediate stop in the ‘park’ position.
How do I Change my wipers to intermittent?
Switch the wipers to the intermittent setting – the wipers will start to sweep the screen as normal. Before the wipers return to the park position, switch them off. Wait, then switch the wipers to intermittent again. The wipers will now work intermittently, using the length of time you waited in step 3 as the delay time.
How long does an intermittent wiper motor last?
You also have low and high speeds to deal with. “Generally” you can pulse the wiper switch and the wiper motor takes care of the rest. So, think of a 1 second pulse occurring at some rate from say 10 to 60 seconds using the low speed winding for intermittent.
Is there a variable delay for intermittent wipers?
It’s a function that’s so common on modern cars it barely merits a mention: variable delay for the intermittent wipers. Older cars often don’t have the variable delay, but many of them can be upgraded very simply.
When did “intermittent” windshield wipers start?
Intermittent windshield wipers were invented by Robert Kearns (10 March 1927 – 9 February 2005), an Indiana man who saw an opportunity to improve on standard wipers. Kearns realized a need for wipers that would work on a delayed switch principle, and designed then patented this invention in 1967.
Is my wiper motor failing?
There are signs that indicate pretty clearly if a wiper motor is failing. These may include the blades moving slower than they normally would, only one speed working, the wipers not moving at all, or not parking in the correct position. If any of these start to happen it is a good idea to replace the wiper motor.
What is an intermittent wiper?
Intermittent wipers. Intermittent wipers is a wiper setting that causes the wipers to pause for a driver-selected period between wipes.
What does the wiper Run Park relay do?
The Windshield Wiper Motor Relay is a part of your windshield wiper system. It controls the voltage input to the wiper motor. The relay senses the position of the wipers and transmits power to the wipers they are in their parked position.
