Garage door light sensor not working

Making your Garage Door Light Sensor Work For YOU

Sometimes a faulty garage door light sensor is caused by something as simple as poor placement, or buildup of obstructing debris on one of the contact “eyes” or infrared (light sensor in this case) sections of your sensor or sensors.

To get started troubleshooting a faulty garage door light sensor first ensure that there are no dirt, cobwebs or other build-ups or objects blocking the way of the light sensor from telling the difference between light and dark – or Off and On.

In some cases it might be necessary to get a ladder and completely remove your light sensor receiving or sending component, and ensure the wiring is put together. Often, burnt wires, or otherwise faulty ones can cause miscommunication, or a lack of communication at all, between garage door light sensors. Also, poor placement has equally been found to be a common culprit.

If possible, unplug or remove the power mechanism for your garage door light sensor, and unscrew the back to check the condition of all of your wires. Re-fasten or tighten any screws connected to what might appear to be poorly connected or untightened sections. If a wire seems poorly connected, it might be necessary to remove the screws and completely re-wrap and tighten the wires to ensure necessary connection.

Are your sensors displaying green or red LED indicators? If not, this is a rather sure-sign that it’s necessary to either repower, or replace the wiring or parts of either your sender and or receiver.

Sometimes cycling your garage door light sensor between Off and On or Open and Close – can trigger the device to sort of troubleshoot itself’.

Even if your light sensor devices are powered by insulated low-voltage wires, it’s worth bearing in mind the dangers of live electrical wire, as well as the probability that without experience or familiarity that it’ll be near impossible – and dangerous – to try to re-wire or fix the wires and connections on your own. Always make sure the plugs, batteries, or circuits to your sensors are completely disconnected or turned off before attempting to open them up or interact with the (live) wiring of the devices.


Qashqai rain sensor not working

Setting your Qashqai Rain Sensors Straight

Determining what might be causing poor functionality or none at all with any rain sensors can be a very frustrating experience. Customers of Qashqai rain-sensors in particular have reported a plethora of various reasoning behind abnormal functionality, or none at all.

It’s worth first taking into consideration the current settings of your Qashqai rain-settings and attempting to alter the level of sensitivity in favor of getting your wipers to work again. Many customers have reported that these rain-sensors in particular are especially insensitive, and in return lead to your wipers ‘not working’ more than half the time.

Some customers in particular report that by simply adjusting your Qashqai rain-sensors one level under maximum is sufficient to get them working again. In other cases, automatic or manually overriding the settings are necessary.

Have you considered crust and grime build up, and any other possible dirt or objects that might be in the way of your sensor device and the receiver?

If you have a GSM holder on the windscreen this could also be the culprit. In fact, some customers have even reported that certain levels of window-tinting directly interferes with their Qashqai rain-sensors ability to function properly and consistently.

Have you attempted a genuine IPA cleaning of your windshield? Some build-up deposits on your windshield cannot be seen with the naked eye. Before resorting to professional assistance, try troubleshooting your windshield by ensuring you’re using mechanic or manufacturer approved window cleaners. Windshields and sensors can be so sensitive that even after a carwash sometimes a vehicles rain-sensors stop working due to soap or other cleaner residue left behind, although often unnoticed.

With regards to troubleshooting, you can try a form of “resetting” the sensor device by also toggling forward or backward one speed, and then returning it to the original, desired speed.
Lastly, and not quite surprisingly, customers have reported that above all else, the Auto setting seems to work best and most consistently.


Nissan murano rain sensor not working

Nissan Murano Rain Sensor Troubleshooting

The Nissan Murano model comes either equipped or optionally (upon request) has a rain-sensor installed.


While rain-sensor technology is especially desirable for rain-filled climates, it is not without it’s flaws. In fact, many sensor issues can easily be fixed through the process of simply relocating your sensor, receiver, or engaging other possible obstructions.

Firstly, consider the placement of your sensor and receiver. If there are any objects, protrusions, or otherwise obstacles that could interfere with either components. An object as simple as leaves, sticks, or even dirt could mean the difference between proper communications between your rain-sensor and receiver. In many cases, vehicle owners have had to relocate at minimum one of either the sensor or receiver to enhance consistency and performance of their Murano’s rain sensor device.

Have you ensured that the factory “terminal jump” has been removed? It is designed to directly interfere or prevent communication between the sensor and receiver. Often, when your mechanic repairs, restores, or replaces parts on your vehicle – specifically sensors – a factory object such as this could still be left on by accident. A jumper clip or wire will be visibly connected alongside of or directly into the circuit, thereby requiring direct removal for proper operation of the rain sensor device.

Have you checked your rain-sensor bypass switch? Many rain-sensor models on the Murano’s come with this, and simply toggling to the “Active” or “On” position can restore or activate functionality of the rain sensor.

Aside from intrusions or instability of connection caused by physical obstacles or poorly assembled locations, radio signal can also be the culprit of malfunctioning rain sensors. To fix this, refer to the Murano’s manual and reset the address for both the sensor and/or receiver to redirect the appropriate commands and compatibility with your uniquely programmed device.
