Windshield Sensor Leaking Fluid?
Hi, wondering if anyone can help or have experienced this. There is a sensor to the passenger side of the windshield (not under the rear view) that is attached to the windshield near the top. In extremely hot weather (above 100F) when the car is parked outside for the day during work, a clear oily liquid leaks out from this sensor area and runs down the windshield. I've experienced this on about 5 occassions and each time i wipe it off. there' is no odor, just clear and oily.
this is a problem as i have a radar detector suctioned to the area where the liquid runs to and the suction cups won't stick if i don't clear the liquid off before installing each time.
Has anyone else experienced this? I'm afraid to make a trip to the dealer since it's not reproducable unless it's really hot. thanks

Never heard of that one. You'll have to make that trip to the dealer with the oil on the windshield. Don't speed w/o your radar detector .

I would rush right to the dealer since you are in California.....We last had rain in April where I am....I think that option was for the minority in Oregon who drive a Lexus!!

Thanks all. At least now I know what sensor it is. I wasn't sure if it was the light sensor for the auto high beam or the rain sensor for the wipers.
I'll call up the dealer and ask about it and perhaps get the floor mat recall taken care of all at the same time.
I just hate hearing "we can't reproduce the problem." I also cleaned my windshield, so now i have to wait for another hot day before i can show the problem.

Interesting. I just bought a 2010 LX350 and I am having the same problem with a slowly leaking rain sensor. Lexus dealer (via phone) says that he has never seen the problem. How did you resolve the problem with the dealer? were they able to seal it, or did they need to replace the entire unit? Thanks for posting the problem.

Kind of off-topic but does anyone know if there's a way to adjust the sensitivity of the rain sensor? I live in a foggy area and often times, the windshield would be covered from the mist of the fog and even though the entire windshield is covered with water, the auto windshield wiper still wouldn't move. Any other folks here experience the same issue?

I believe it's on the wiper stalk. Rotate the dial to the highest setting.

Issue was identified and fixed by the dealer. The rain sensor is attached to the windshield with gel tape. In heat the gel tape shrunk and the gel melted causing the oily run. Dealer replaced the tape and remounted the sensor and no more issues. Lets see if it gets through the summer with no problems.

I'll usually just pulse the wipers once then it's fine.
Put the old Buick away about a month ago & Jane now gets to park in the garage. This will likely make the issue disappear. As soon as she backs out in rain/fog, the detector will see the change in state of the glass clarity.
