My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Hi there – the lack of slow or intermittent motor speed can be caused by 2 issues: failure of the switches on the steering column stalk, or within the motor pulse control inside the motor housing. You’re going to need a voltmeter to check power to the motor for low speed to isolate this one to either the motor or the switch. I recommend an electrical inspection by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

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.
Most wipers have a low and high speed, as well as an intermittent setting. When the wipers are on low and high speed, the wipers move continuously. But in the intermittent setting, the wipers stop momentarily between each wipe.
The intermittent DC relay is used for controlling the windshield wiper`s operation. Working with automotive combined switch and windshield washing control switch, the relay controls the operation of the wiper motor.
The relay switch sends an electrical signal to the module that controls the operation of the wiper motor and gears inside. When the relay is faulty, the windshield wipers will only work at the same speed that the last relay signal was sent.
Generally, the wiper control module is located under the dash, but it can be found in other places as well. If you have a hard time locating the module, consult the factory repair manual for the location.
A control signal is produced by digitally processing the pulse signal. The control signal is applied to a wiper driver circuit to adjust the operational speed or timing in accordance with the control signal.
Use the rotary control to adjust the intermittent wipe interval. Speed Dependent Wipers. When your vehicle speed increases, the interval between wipes decreases. Push the wiper lever up to switch the wipers on. Use the rotary control to adjust the intermittent wipe interval.
Grab a multimeter and set it to Ohms. Touch the leads across the electromagnet coil pins and measure resistance. Anywhere from 50-120 ohms is OK. Out of range or open means a bad electromagnet coil winding and time for a new relay.
Here are some of the most common reasons your windshield wipers aren`t working: Your wipers are frozen or snowed on to the windshield. Your windshield wipers don`t weight very much so its easy for heavy wet snow to weight them down or cause them to freeze onto the windshield. Your wipers aren`t fastened in properly.
Most rain-sensing wipers use a sensor that`s mounted behind the windshield. It sends out a beam of infrared light that, when water droplets are on the windshield, is reflected back at different angles.
When windshield wipers are slow, it may be caused by a problem with the wiper motor. Sometimes the mechanical components inside the motor are clogged and it can impact the motor speed. If you experience this, you should contact a garage as soon as possible.
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.
Move the windshield wiper lever to AUTO. The Driver Information Center will display that Rainsense is enabled. Turn the Rainsense sensitivity band UP for more sensitivity to moisture. Turn the Rainsense sensitivity band DOWN for less sensitivity to moisture.
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.
L298N Driver
The L298N is a dual H-Bridge motor driver which allows speed and direction control of two DC motors at the same time.
Brushed motors working principles
Brushed motors generally operate at low speed and can be driven by a simple pulse width modulation (PWM) controller to vary the voltage supplied to the motor to control the speed in one direction and provide the torque for the motor drive.
Look for recent cracks, chips, nicks, or warping. Study the area where the rain sensor is located. There can be no cracks or chips in that place. If you find chips or cracks, particularly in the area above the sensor, you will need to repair the crack or replace the windshield.

Dirt in the Nozzles
One of the most common causes of screenwash issues is clogged washer nozzles. This happens when small particles of dust and dirt get in the nozzles attached to the top of the bonnet, preventing the spray from working. Use a safety pin or needle to prod inside the nozzles and clean the blockage.

Intermittent and low speed wiper don’t work fast speed wiper works 2014 Chevrolet Silverado 1500
ANSWER : Hi there – the lack of slow or intermittent motor speed can be caused by 2 issues: failure of the switches on the steering column stalk, or within the motor pulse control inside the motor housing. You’re going to need a voltmeter to check power to the motor for low speed to isolate this one to either the motor or the switch.

Windshield wipers stopped working. They’ll suddenly stop working then suddenly start working again. Has been happening for a week.
ANSWER : The problem you are describing likely stems from an intermittent electrical fault in the wiper circuit. The windshield wiper system uses a small electric motor to move the wiper arms that you see on the windshield. That electric motor is controlled through a switch, relay, fuse, and wiring. One, or more, of those electrical components has failed although it is also possible that the mechanical arms are binding (seized, if the lubricant has dried out) thus causing the electric circuit to the motor to overload. Regardless of the underlying fault, if you request a non functioning wiper diagnostic/repair, the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
My dash board don’t work my front light work when I change my light into high beam and my back window won’t go down
ANSWER : As unfortunate as it is, your vehicle would be considered flood damaged. Diagnosing electrical problems in a flood damaged vehicle is nearly impossible. This would take many hours or even days to determine which wiring harnesses and circuits have been affected. Then nearly all of the wiring under the dash would likely require replacement as well as many sensors and switches. On a BMW vehicle, the amount of wires and switches are likely more than that of a lower end vehicle. Due to the inefficiency in cost, you would likely be able to purchase another BMW like yours for less than what it would cost to fix your car. Many insurance companies would consider this type of damage to total out the vehicle unfortuantely.
Wiper speeds not consistent, and wiper failures
ANSWER : For your vehicle there is a recall for this problem, you should be able to get your faulty wiper module replaced. Contact your local dealer to check your vehicle identification number with them to perform this and any other recalls that may be valid for your vehicle. If for some reason you are not included under the recall, replace the wiper module to correct the condition. A certified mechanic could help you get this done at your own convenience.
Both R&L low beam headlights quit working simultaneously.
ANSWER : Hi there. Check the switch to the headlights and see if there is a break in the wiring. Check the fuses and see if there is any fuse that are blown. If the fuses are good and there is no break in the wiring, then either the switch has failed or the ballast resister has failed on the low beam circuit. Turn on the switch and check for power coming out of the switch. If there is power to the switch and power out of the switch, then I recommend replacing the ballast resister. If there is no power coming out of the switch, then the switch needs replaced. If you need further assistance with diagnosing the low beams, then seek out a professional, such as one from Your Mechanic, to help you.
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.
One of my car’s headlights does not work
ANSWER : Hello. There are 2 devices in the front wiring of your vehicle called "Signal Acquisition Modules." One is for the left side of the front, the other is for the right. They act as an electrical "router" and power distribution module for electrical loads up front. These modules take signal pulses from light switches and other controllers, and turn on power to the requested device.
The SAM units have fuses in them, just as a traditional box would. I would check the fuses in each SAM for both low and high beams, then check the igniters for the xenon low beams. If this seems a bit intimidating, I recommend having a certified mechanic, such as one from YourMechanic, come to your location to inspect for any electrical problems and suggest the needed repairs.
