My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
The low fluid sensor is mounted inside the washer tank. The sensor may have been contaminated with different typed of cleaning fluids or contacts blocked with debris. I would recommend cleaning out washer tank and sensor to see if this fixes the sensor. If it still will not register full then replace the sensor.

Windshield Fluid Warning Light is always on

Another common sign of a broken windshield fluid level switch is when the warning light stays on all the time – even if the tank is completely full. The level switch is designed to measure volume inside the storage tank.

Check the Fuse

With the car parked in a quiet place, operate the window washer and listen for the whirring of the pump. If there`s no sound, head right for the fuse box. If the fuse is blown, it`s usually a sign of a dead pump motor or one that`s ready to check out. If it blows again, replace the motor.

The washer fluid low light warns you when your windshield wiper fluid needs to be checked and refilled soon.
Use The Gas Pedal

You may have to reset the signal if you`ve refilled your washer fluid and still getting the warning sign. To do this, turn the ignition and push your gas pedal downward five times. You must do this quickly (within three seconds). This will reset the light.

Listen for the pump whirring and see if you can feel any vibration when the switch is activated. If you can`t, the pump is faulty; if you can, there`s likely a blockage or a leak from the reservoir. If the pump isn`t working, turn the power off and access the bottom of the washer reservoir.
Tip: Typically, the washer pump is on the same fuse as the motors that control the wiper arm. If they share a fuse and the wiper arms still move when you turn them on, then you have a faulty pump.
Always keep your windshield clean and clear, and make sure you have plenty of wiper fluid in your washer system at all times. Without wiper fluid, you can risk having a streaked or smeared windshield, which can ultimately compromise your safety on the roads.
Window washer fluid is mostly alcohol and water so there shouldn`t be any engine harm.
In most cars, the windshield washer fluid tank is located in the engine bay or around the front wheel wells, often behind the front bumper or one of the front fenders. The washer fluid pump/motor and the washer fluid level sensor are attached to the windshield washer fluid tank.
Pull the hose off of the nozzle at the jet as well as the nozzle at the reservoir, then use an air compressor or can of air to force air through the line and remove any blockages. If the air cannot pass through the line to unclog it, you will need to replace it.

Washer fluid is normally blue, but can be other colors depending on the manufacturer. “I particularly like RainX Winter Fluid, because it does help clear the windshield and it puts a light RainX coating for when it rains,” Steve`s Auto Repair & Tire Owner ST Billingsley.
Can I drive with the low washer fluid warning light on? Yes absolutely. If the light just came on you may even have a bit of washer fluid left to clean your windshield.

I’ve filled my washer fluid up but the light saying it’s low is still on
ANSWER : The low fluid sensor is mounted inside the washer tank. The sensor may have been contaminated with different typed of cleaning fluids or contacts blocked with debris. I would recommend cleaning out washer tank and sensor to see if this fixes the sensor. If it still will not register full then replace the sensor.

Abs light, emergency brake light, steering wheel assist light, engine light, EPC light, traction control light
ANSWER : Hello, thank you for writing in. The vehicle does utilize a lot of the same sensors for these systems. Are there any other codes that are coming up when this code appears? If so you will want to take these into consideration when processing the repair and making a diagnosis. The module may be bad, and replacing it should fix the problem. The lights should turn off once the main computer recognizes the new module and the sensors sync up. If you believe the sensors need to be cleaned you may do so. Do as minimal as possible to make sure you are not damaging the sensor or disrupting the wiring inside. A bad connection would make the lights stay on. With so many lights that are effected by the module being illuminated, the module is likely bad or does not have a connection. Check the connection first and then resort to replacing the unit.

Brake lights are not working. replaced brake light swtch still no brake lights. the third brake light the connection was melted at
ANSWER : The first thing to do is to repair third brake light and replace the brake light fuse and then see if the third brake lights work and the lower lights start working? If only the 3rd brake light starts working then you may need a further checks on the turn signal flasher or switch could be bad.

No dash lights, back right tail light is out, no parking lights. Brake lights work though as does head lights.
ANSWER : Hi there. In many cases, when you have electrical problems like you’re describing, it’s caused by multiple electrical component failure. It’s likely that a few electrical relays are not working; especially if you have systems that utilize the same components (such as your brake light and tail lights). I would recommend having a professional mobile mechanic come to your location to complete an electrical problems inspection first, so they can pinpoint what is damaged and recommend the right repairs.

Low coolant light comes on when AC, defrost or heater is on, but only if the car is in gear and stopped, what’s wrong with my car?
ANSWER : First, you want to make sure your cooling system is full. Check the radiator not the coolant jug. And check it when it is cold. If it needs coolant, add some. Of course, I don’t feel this problem is an actual low coolant condition. I would expect to find an electrical failure in the instrument cluster or from a component or wiring harness that is connected to the instrument cluster.

As a technician, I have access to reports from technicians across the country. I could not find any reports of this problem, so diagnosing this will require an experienced tech as this is not a common problem. In addition, this happens at intermittent times making it difficult to recreate. The most challenging part of this diagnosis will be recreating the symptom. I suspect it has something to do with the brake switch circuitry because it only seems to happen when you have your foot on the brake. I would begin my diagnosis there with a wiring diagram and test light in hand. The brake switch, instrument cluster, and environmental controls all interact with each other. Something is crossed either because of a failed module or damaged wiring in a harness.

Aside from making sure the coolant is full, this will not likely leave you on the side of the road. If you take it in to be diagnosed, be prepared for them to spend more time than usual to figure it out. Since it isn’t a key problem, you may need to live with it until it completely fails making it much easier to diagnose. Either way, I do recommend having a certified mechanic diagnose the warning light to make sure there isn’t anything serious going on.

Good luck.

All my exterior lights work (brake, signal, hazard, reverse, etc.) EXCEPT running tail lights
ANSWER : If you are certain all fuses are good/tight, grounds are good and all bulbs are correct in voltage for the vehicle, I have a suggestion from personal experience with a MK 5 Jetta sitting right outside. Make sure the front marker lights are working. The issue we were experiencing with this Jetta was similar. When switching the lights on, the left rear marker would light for a brief moment, then go out and set a bulb fault on the instrument cluster.

After spending a bit of time on that, we found the left FRONT marker light in the headlight housing was out. The bulb was found to be good upon removal and inspection, but the terminals had a bit of corrosion, giving a poor ground. After cleaning the contacts with a bit of emery cloth and reinstalling the socket, both front and rear bulbs are working properly.

ABS light on, ESP light on,Traction OFF light on, engine light on, rides perfectly OBDI reads only Front Right Wheel Speed Sensor
ANSWER : If a faulty component is still in place, the fault codes will return almost immediately after clearing them. ABS, ESP, and traction control systems all rely on input from wheel speed sensors to determine as the name implies, the speed of each wheel. When a wheel, or wheels are spinning faster than others due to wheel slip or the vehicle is sliding, the ABS and ESP systems can reduce throttle input as well as apply braking to an individual wheel or all of them if needed. With a wheel speed sensor fault code stored, these systems cannot determine the rate that all 4 wheels are spinning and sets a fault. That is why the abs/esp light is on. The system should be scanned by a certified technician and the wheel speed sensor replaced if found to be the cause. The warning lights will stay on and these systems will not function as designed until the fault is corrected. These lights do not come on to indicate a need for routine service. Rather they only come on when a component in the system is at fault.

washer fluid hasn’t been coming out nozzles to windshield, yet within 12 hrs "refill washer fluid" notification comes up – leak?
ANSWER : Before replacing the reservoir, you should check the hoses to see if there are any leaks. It could be something as simple as a hose coming loose or breaking. If you are certain it’s the reservoir, then I would go ahead and replace it. If you would like to have this checked, have a local expert inspect the windshield wiper system so that this can be resolved properly.
