What should I do if my rain sensor is not working?
Use a magnifying glass to inspect the entire outside surface of the windshield. Look for recent cracks, chips, nicks or “bull’s eye” deformations. Study the area where the rain sensor sits. There can be no cracks or chips at that location.
How does a rain sensing wiper sensor work?
A sensor attached to the front windshield behind the rear view mirror operates by using an infrared light. The infrared light shoots a beam through the windshield at a 45-degree angle. Anything on the window that disrupts that beam triggers the sensor to activate the wiper. Place the vehicle in park or neutral with the emergency brake set.
How does a rain sensor work on a car?
Rain sensors automatically detect rain, snow or moisture on the windshield. They adjust the wiper speed depending upon the accumulation of water drops on the window’s surface. This allows the vehicle owner a hands-off posture while driving through rain, mist and snow.
What to use to clean rain sensing wipers?
Use a spray bottle of window cleaner to soak the inside of the front window. Wipe the window’s surface clean with towels, removing all stains, such as coffee, tobacco, any haze and hand prints. Clean the outside of the front window with window cleaner and towels. Remove all bug stains, bird droppings, oil film, mud or other debris.

Where is the rain sensor on my windshield?
Use extra effort around the location of the rain sensor mounted on the inside window in front of the rear view mirror. Use a magnifying glass to inspect the entire outside surface of the windshield. Look for recent cracks, chips, nicks or “bull’s eye” deformations. Study the area where the rain sensor sits.
Where is the rain sensor on a Nissan Leaf?
It should be in the fuses under the driver side to the left of the brake against the wall. There is a panel you need to remove. Not sure if you are aware but you also adjust the sensitivity of the rain sensor by turning the wiper speed dial up and down.
Why are my Rain sense wipers not working?
The fuse is actually one of the switch things that the factory pulls out (off) during shipping. I pulled it out and pushed it in a few times. It doesn’t seem to come off completely…atleast that I’ve found a way to do. The rain sense wipers, as you know, use a sensor on the windscreen.
What should I put my rain sensor in?
The sensitive coupling medium should be covered by a clean and dry plastic film. To protect the sensor from electrostatic damage, it should be put into intermediate storage in a dry plastic box. The function of the rain sensor can be easily tested by simulating precipitation on the windscreen.
How does the rain sensor adapt to the windshield?
The rain sensor adapts permanently to the relevant windshield condition in the sensor area. Age-related signal changes caused by scratches or contamination are taken into account by corresponding adaptation routines in the software of the sensor and/or control unit.
Where is the rain sensor on a Hella?
Initially integrated in the mirror base of the rear-view mirror, the rain sensor is fitted on the inside of the front windshield outside the driver’s field of vision. Within the sensor area, the sensor detects when it is raining and transmits its information to the windshield wiper’s control electronics.
When did the rain sensor start in cars?
In the mid-1990s, the rain sensor started to be fitted in vehicles and since then has been a permanent feature of modern vehicle electronics. The following technical information and practical tips have been compiled by HELLA in order to provide professional support to vehicle workshops in their day-to-day work.
