Intermittent Windshield Wipers move 1/4 of the way

2015 Encore AWD – Intermittent Windshield Wipers, as well as using the squirts – the wipers will wipe up completely normally, and on the return, only return 1/4 of the way. Requiring multiple wiper lever presses to return the wipers to their starting position. This is also the case with the rear wiper. A couple times it continued for my entire drive (about 20 minutes), a couple other times it seemed to correct itself about half-way through the trip. The Encore is a lease that i've had for a little over a year, not sure if it would be something that would be covered by warranty or somethin

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.
26″ Wiper blade.
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.
Windshield wipers are operated by an electric motor. The electric motor is attached to a worm gear, which transmits the necessary force to a long rod that sets the wiper arms in motion. The worm gear is able to generate the force required to move the wipers as fast as they need to move.
INTERMITTENT FAILS

Check the wiring, connectors and switch contacts. If OK, suspect a faulty intermittent control box. If the wipers stop halfway, check wiring to the self-parking circuit from the switch and control box.

When adjusting the windscreen wipers, you must twist the wiper blades over the wiper arm. Be very careful when doing this because the material is flexible and can easily break if too much force is applied or it`s twisted too much. Therefore, always adjust the angle in small steps only.
A short cam is attached to the output shaft of the gear reduction. This cam spins around as the wiper motor turns. The cam is connected to a long rod; as the cam spins, it moves the rod back and forth. The long rod is connected to a short rod that actuates the wiper blade on the driver`s side.

Wiper has to manually be lifted before working – 1996 Chevrolet Beretta
ANSWER : You will have to replace the "wiper arm shaft" and/or wiper arm for the side which isn’t working. Both of these components have very small splines which interlock when the nut is tightened. A heavy snow or ice load can cause the splines to break down, or strip, rather than damage the electric motor. A certified technician from YourMechanic can replace the windshield wiper arm at your home or office.

my rear windshield wipers move very slow and sometimes even stop. I am sure they could never move snow
ANSWER : When wipers move slowly or not at all, that can indicate a couple of things. The wiper motor may have failed. It could be damaged internally or simply worn, not producing enough power to even move the wiper correctly. Also, loose or damages linkage between the wiper motor and wiper arm can be at fault. There can also be an electrical issue that is reducing power to the wiper motor.

TIP: Neither front or rear wiper motors or linkages respond well to the heavy weight of snow. It is always best to clear the vehicle of snow before driving off, and not relying on the wipers to clear a heavy snowfall. That damages the linkage and motor over time, or even immediately in many cases.

Have a certified technician inspect the rear wiper system to locate the exact cause.

Windshield wipers move slow and get stuck
ANSWER : A few different items can cause the windshield wipers to work slow. The most common causes are the windshield motor beginning to fail, poor electrical connection at the windshield motor, or high resistance at the wiper motor.

Windshield wipers not moving.
ANSWER : The wipers on your vehicle are powered by a multi-speed motor that is controlled by the wiper switch and a relay module. A set of gears, crank arm, and linkage attach the motor to the wipers. If you hear the motor running and the wipers barely move, the problem is likely in the linkage. A professional will be able to remove the cowl and underhood seals to determine the exact cause. I suggest you have a certified technician inspect your wipers to pinpoint the cause of your problem.

How do I adjust the intervals of the windshield wipers on intermittent operation?
ANSWER : Sometimes you’ll want the windshield wipers to be working, but not at a steady pace. You may be driving through a light rain or just a few sprinkles. Intermittent operation can be adjusted to activate the wipers at the right times.

Locate the dial on the windshield wiper lever. It’s located just below the end grip.
Turn the dial upwards to increase the frequency at which the wipers operate.
Turn the dial downwards to slow down the frequency at which the wipers operate.

Need instructions to set timing on windshield wipers
ANSWER : The process can be very difficult and there is some steps that require turning on the wiper to intermittent and then measuring the alignment.
