Are there sensors on my windshield?
Automatic headlight sensors that detect light levels are located at the bottom of the windshield, just below the defogger. There are also heated windshields that melt off snow and ice. Advanced driver assistance systems, known as ADAS, usually have sensors inside the windshield.
Where is the rain sensor on windshield?
rearview mirror
The rain sensor is mounted beside the rearview mirror in such a way that it is in contact with the windshield. A small portion of the windshield is blackened to hide the rain sensor. However, there is a tiny view port which is not blackened and through which the sensor is able to detect rain.
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.
How does a rain sensing wiper work on a car?
Rain sensing wipers have been a fairly recent development on vehicles. 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.
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.
What to do if your windshield wipers do not move?
Turn the ignition key to the “On” position. Turn the rain sensor switch to the “On” position. If the wipers do not move, refer to your owner’s repair manual for the location of the rain sensor module. It will be a small plastic box that receives the wires from the sensor.
How do you test a rain sensor on a car?
Use a spray bottle to wet the outside surface of the front windshield until you see water heavy beads. Turn the ignition key to the “On” position. Turn the rain sensor switch to the “On” position. If the wipers do not move, refer to your owner’s repair manual for the location of the rain sensor module.

Is there a crack in the rain sensor?
Study the area where the rain sensor sits. There can be no cracks or chips at that location. If you find chips or cracks, particularly in the area above the sensor, you will have to repair the crack or replace the windshield. The infrared sensor beam will deflect off any crack or chip and fail to function properly.
How do you turn off the rain sensor?
Disconnect the negative battery cable with an end wrench. Go to the wiper control switch on your vehicle. Spray electrical contact cleaner into the switch seams and rapidly work the control on and off, or turn to the knob dial. Spray contact cleaner on the “On/Off” switch to the rain sensor and activate the switch several times.
