Some customers may comment that an oily substance is found on the inside windshield surface and appears to be leaking from the rear view mirror area.

</dd></dl><dl><dt>Recommendation/Instructions</dt>
<dd>
The oil/fluid is from the gel pad of the moisture sensor, the oil/fluid can separate and leak due to heat loads.* The sensor should only leak one time and leakage will not affect the performance of the sensor.


Note: Only 1 gram of oil is used in the sensor – so the leak will be minimal. As such, driver visibility will not be impacted.


Inspect the moisture sensor for being the source of the leak,* If found to be leaking, carefully remove the moisture sensor by gently rocking the sensor in the bracket and pulling down with constant pressure.

Important: Use care to avoid touching the gel of the moisture sensor. Using excessive force*to remove may cause the gel to separate from the sensor.*Any sensor that experiences gel separation should be replaced.



Clean the glass surface and sensor bracket with an Isopropanol Alcohol wipe until the surfaces are clean, then re-install the moisture sensor.

Test the moisture sensor by placing the ignition in the run position and rotating the wiper switch Intermittent (delay) band fully forward.* Once the wipers wipe once, apply water to the windshield in the area of the moisture sensor with a spray bottle. After one or two sprays, the wipers should wipe.

No oil yet on my '14 ATS. Then again, maybe it has been in the sun enough to cause it to leak.
