What is intermittent wiper?

Most wipers have a low and a high speed, as well as an intermittent setting. When the wipers are on low and high speed, the motor runs continuously. But in the intermittent setting, the wipers stop momentarily between each wipe. It can require almost constant attention to keep the wipers operating properly.

How do intermittent wipers work?

The intermittent wiper relay gives you this feature. The relay functions as a switch and energizes circuits as needed. In the case of your windshield wipers, it controls low, high, and intermittent speeds by energizing a particular circuit at a given moment depending on what speed you have your wiper switch set to.

Do I have intermittent wipers?

Common signs include the wiper blades only working on one speed or a different speed than you selected, not working at all, and making humming noises.

Who invented the intermittent wiper?

Robert Kearns
Robert Kearns, 77, Inventor of Intermittent Wipers, Dies. DETROIT, Feb. 25 – Robert W. Kearns, the inventor of intermittent windshield wipers, who won multimillion-dollar judgments against Ford Motor and Chrysler for using his idea, died on Feb.

Did Ford really steal intermittent wipers?

Kearns won one of the best known patent infringement cases against Ford Motor Company (1978–1990) and a case against Chrysler Corporation (1982–1992)….

How do you adjust intermittent wipers?

If you set the wipers to work intermittently, you can change their tempo. On the wiper stalk, you’ll find a dial. Turn it up to set a shorter interval between each wipe. Turn it down to set a longer interval between each wipe.

How do I change my intermittent wiper relay?

Part 1 of 1: Replacing your intermittent wiper relay

1. Materials Needed. Owner’s manual.
2. Step 1: Locate your relay. Many late model vehicles can have multiple locations for fuses and relays.
3. Step 2: Remove the relay. With the ignition in the off position, remove the relay.
4. Step 3: Install the new relay.

How do you make intermittent wipers?

How to use it

1. Switch the wipers to the intermittent setting – the wipers will start to sweep the screen as normal.
2. Before the wipers return to the park position, switch them off.
3. Wait, then switch the wipers to intermittent again.

Did Kearns win against Ford?

Kearns won one of the best known patent infringement cases against Ford Motor Company (1978–1990) and a case against Chrysler Corporation (1982–1992).

What controls wiper speed?

rain sensor
Now, virtually all automotive wipers are controlled by a microprocessor. Many wiper systems in cars today use a rain sensor to detect the speed at which the raindrops are falling on the windshield. A microprocessor evaluates the signals from the sensor to calculate the speed at which the wipers should move.

What is wiper mechanism?

This model shows an application of a four-bar mechanism that converts the rotation of an electric motor into the sweeping motion required for a windshield wiper mechanism. The friction between the wiper blades and windshield is accounted for in the Bearing Friction component.

What does intermittent wipers mean?

Intermittent wipers is a wiper setting that causes the wipers to pause for a driver-selected period between wipes.

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 are speed sensitive wipers?

Speed sensitive wipers, also called rain sensitive or rain-sensing wipers, are a safety feature on newer cars to help with visibility in bad weather. Windshield wipers have been around for almost a century. They were added as standard safety equipment to most cars in 1916.

Where is the windshield wiper fuse located?

The windshield wiper fuse is located in the fuse junction box under the left side of the dash. The fuse is a 25 amp fuse. It will be labeled wiper. Check the fuse to see if it is burned out.
