Rain sensing wipers (if equipped): The rain sensing wipers will
automatically activate when moisture is present on the windshield and
the multi-function switch is set to one of five auto/interval moisture
sensitivity settings. Rotate the end of the control toward the windshield
to increase the sensitivity. The speed of the rain sensitive wipers will
vary based on the amount of moisture detected on the windshield and
the auto/interval setting. There are no interval (intermittent wipe)
settings on vehicles with rain sensing wipers. The wipers will continue to
wipe as long as the presence of moisture is detected on the windshield.
More or less wiping may occur depending on humidity, mist or light rain,
or road spray.
Keep the outside of the windshield clean, especially the area around the
rear view mirror where the sensor is located or rain sensor performance
may be affected.
Note: During winter driving conditions with ice, snow or a salty road
mist, inconsistent or unexpected wiping or smearing may occur. In these
conditions, you can lower the sensitivity to reduce the amount of
smearing or override the feature by selecting low- or high-speed wiping
or turning the wiper system off.
Note: The wipers must be turned off before entering a car wash.
Thanks for your response. I have set the wipers on the lease setting and they wipe almost continuously. The one on my 2008 Tahoe are not as sensitive which was ok with me. These are like not having any itermittancy at all.
My 11 is going in the shop tomorrow because sometimes it works just fine then it will go to high power for two drops. Then goes back to normal for a while. Doesn't matter what speed setting. I think the IR sensor might be going bad.
