Supersession Statement
This PI was superseded to add Models. Please discard copies of PIC6086F.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in
this PI.
Condition / Concern
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.
Recommendations / Instructions
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.
