Auto-wiper insanity

TheWidup · May 25, 2018

My experience with the auto-wipers is mixed at best. Occasionally they'll run a swipe when there's no rain. Sometimes it'll be pouring rain and they don't turn on unless I flip it up to a faster speed. Other times they run great. Then other times they run wicked fast for about a minute and then go oddly intermittent.

Is the programming logic on these that bad or do I have some sort of connection issue with the sensor to the windshield? It's the original windshield with the heater.

I leave the stalk in the Off position - this prevents sudden wipes out of nowhere, I think certain reflections on the sensor can trick it at times, and also prevents them from working furiously inside car washes, which could actually damage them... I only flip it to Auto when I see the first droplets of real rain collecting on the windshield. I never liked auto wipers much personally, but I find that mine work almost to my liking - almost (I also turned the sensitivity trimmer knob on the stalk to the slowest position, as I find them overactive otherwise.) Of course, living in Southern California I don't get to ***** too much about them, it's almost a friggin' miracle when we get measurable rain here.

Also have the heated windshield, auto wipers operate just fine. That being said I do exactly what Umberto does.

Been in a bunch of cars where the wiper just turns on out of nowhere.... really annoying!

Replacement windshield? Or OEM installed? Ours is a replacement and it sketchy. Needs to have the attaching pad replaced.

It’s OEM. It seems it goes nuts if I flip it from lowest to anything higher and back during rain. I guess I’ll just keep it off pop it on when it actually does rain and see how it goes.

The rain sensor cover just snaps off like a claim shell if I remember correctly and you can see if it is attached correctly under the cover.

You can buy the pad clean it up and replace.

If you unplug the rain sensor they will revert to regular timed interval intermittent, and should also respond to the time gap/sensitivity setting.

How do you unplug the sensor? The sensor on my 2010 LR4 is very erratic. I was rather set the intervals and disable the sensor.

It's a rain/light combo sensor. Unplugging it may disable your automatic headlights as well (and I'd be surprised if you didn't get a fault somewhere on the dash.)
