Angry Re: Rain Sensing Wipers

How about this...the complete opposite of everyone else when I turn on my wipers they start slow and over a 30 second period they are on the fastest speed even if im in a light mist...im sitting right now in my truck on the first sensitivity in a parking lot in queens and it is barely raining and my wipers are going a mile a minuet. Any ideas?

Re: Rain Sensing Wipers

Can anyone confirm the following for me...

If auto wiper setting is on, but the wipers are in the off position on the stick, the wipers won't come on automatically?

Therefore, despite being "auto", in order to get them working you need to move the wipers from the off position to one of the detents?

And furthermore, if i leave the wiper setting in one of the detents when it's not wet or raining during the day the headlights will remain on until i move the wiper setting back to the off position on the stick?

Only had my WK2 for 3 days, and it hasn't rained yet!

Assuming you have rain-sensing wipers, correct. They need to be at least in the first detent in order to start if your windshield starts getting wet.

Similarly, if you have the auto-high beams selected via EVIC, the auto feature only works if you move the stick to turn on the highbeams and then let the computer control when they should actually be lit. Having auto-high beams on but the high beam stick in off renders the auto-high beams useless.

Correct. This is to stop them from coming on when you don't want them on, e.g. when washing your car.

A bit of a confusing subject for me since I'm in Canada and we have DRL however I believe you can modify the setting in the EVIC whether or not the headlights come on when the wipers come on. If you have it set to turn on lights with wipers, my guess is that as long as the wipers are not turned off that the lights will be on. But that's only an untested guess at the moment.

Re: Rain Sensing Wipers

I too Have the issue of slow then fast then slow when the rain hasn't changed.. Just drove in the rain tonight and hafta say I am leaning toward turning the feature off. I tried hanging the sensitivity and really didn't notice any difference. And it seemed like I was blinded by a water covered windshield alot. Drove in rain in day light yesterday and didn't notice a problem. But at night I had a tough time seeing. So does it change with vehicle speed? So if im at a stop light I won't have my windshield as clear as if I moving? Even if it is raining hard?

Re: Rain Sensing Wipers

The headlights can't be on even when the wipers are set on one of the "detent" positions if the wipers aren't actively moving.

Same here. Drove in the rain all day yesterday and can say I don't like the feature. I have the same issue. There will be light rain or drizzle and the wipers will vary from intermittent to full speed for no reason. It really annoyed me. I turned the feature off later in the day. I'll stick to picking my own speed for the wipers.

Re: Rain Sensing Wipers

I have the rain sensing windshield. (2011 JGC limited) I recently took a rock to the windshield while driving. Had to get the windshield replaced. Did not get the MOPAR replacement windshield. Instead got a pinkerton windshield. The rain sensing wipers with the new windshield do not work as well as they did with the original windshield. Is there an way to adjust the sensitivity of the sensor? I know there are five sensitivity settings on the stick. When I have it it the most sensitive position, the windshield cold be completely covered in water and it will not wipe. It works very sporadically. Just wandering if there is anything on the sensor itself that can be adjusted?

Dear Sir,
I feel my rain sensitive wipers are the same way. Driving at night in the rain, I adjusted the sensitivity setting and all four sensitivity settings seemed exactly the same. It was raining pretty hard and the wipers were just not keeping up. It seemed like there was no difference whatsoever between the least sensitive auto wipe and the most sensitive. I had to go to manual always on to be able to see that night. Could there be something wrong with the programming on my wipers or perhaps the stalk is not changing the sensitivity setting for each of the four indents? Any thoughts or opinions would be gladly received. :-)

~Tom

Re: Rain Sensing Wipers

The one good thing is that Jeep allows you to go to manual wiper mode. First thing I did when I got my Overland was set them to manual. My Cadillac also has them and I wish you could turn the feature off as it also exhibits all the problems that the Jeep users are complaining about. Another Jeep feature I always turn off is the automatic headlight dimming.
