Automatic Wipers Not Working...

[ugadawgs311]

My automatic wipers on my 2007 Tahoe do not work. Whenever I have them on any speed setting, the only wipe once, then never again. The only way to get them to continually wipe is to set them on the highest or second highest speed (which is quite annoying when it's not raining that hard). All other speeds don't work. I've read around a lot on the web and can't find any solutions.

Does anyone know how I could fix this problem? Thanks for any help.

Do you have the sensor option?

Do you have the sensor option?

Yeah I assume so. I see the black, circular box behind my rear view mirror. It obviously doesn't work though...

Actually it seems like it is working. From your description, when it is not raining hard the wipers do not wipe that frequently. Try the same thing and pour water over the sensor on the windsheild.

For me it did not operate correctly (the way I wanted especially during winter or offroad) so I disconnected it and now it works like normal intermittent wiper.

No, the wipers don't wipe at all. If it is pouring outside the wipers will not turn on at all unless I set the speed to the fastest or second-fastest speed. If I leave it on one of the lower speeds, it will not wipe. So my only option is no wiping or the fastest speed. I may just have to disconnect the automatic sensor.

Yeah that's not right, it seems like the sensor is messed up. Just pop off the plastic sensor cover, unhook, and reinstall cover.

Let us know if that works.

The rainsense wipers suck. My 07 denali did the same as you are experiencing, so did my dad's 08. Pull the cover off the black box above the rearview mirror, disconnect it, and they'll work like normal intermittent wipers.
Supposedly the sensors go bad but they are expensive and still may not fix the problem.

i think they have to work on them cause ppl that get snow it dont feel snow have to keep hitting the mist to see were im going. plus if u have a system and its rain i know it stops them from coming on.

So, when you disconnect them, instead of the stalk position determining "sensitivity," it controls the "interval," and wipes (say, every 3 seconds on a given setting) no matter the amount of rain? I think I'd much prefer that.

Yeah when you disconnect it, it works like typical intermittent wipers. Like you said, once you set the timing it will stay at that rate.

Thanks! And is it pretty clear how to get to the wiring behind the black box on the windshield? (I haven't examined mine -- and don't want to break anything it getting to it.) How exactly does the box come off?

You'll see once you look at it; it's pretty simple. The wires go into the unit on the passenger's side. Just unhook those, put the cover back on, and you should be good to go. I just tested this in my driveway and everything appears to be working; my wipers work just like regular wipers now.

Before you pull it off, there is a little sliding piece that goes into the headliner. Slide it down before you pull the cover off. There is a plug there I believe.

Pop off by hand on the passenger side first. It comes off easily and you shouldn't have to force it.

For the 2010 Tahoe LTZ model, does AUTOMATIC meNan they come on once the sensor senses rain or do I have to have it in a setting?

In my Audis and my Volkswagen R32, my auto rain sensing wipers came on as soon as the sensor sense rain/snow.

Is there not an option in the dic to turn off the auto wiper?

Some customers may not understand the DELAY positions on the wiper/washer switch, which are used to activate the AUTOMATIC rain sensing operating mode. The DELAY positions are also used to adjust the level of sensitivity to moisture accumulation, which determines the dwell time for commanding a wiper motor wipe cycle.

this is from our manuals. is it possible it's just not raining hard enough for them to cycle as much as you want them too?

Yes, they come on when they sense rain/snow IF your truck is equipped. From what I read they removed the automatic wipers in the 2010's and newer.

I have had no problems with mine whatsoever, I love the feature.

Thanks bro.

It does state that I have the Auto Wipers, I just don't know how to use them... do I need to set the wiper One Click?

There are 5 clicks before it goes to always on (I believe there are at least... it might be 3), the further from "off" you go, the higher the sensitivity increases.

to answer your question, yes
