I'm thinking of pulling the plug on the rainsense. 2 times in the last 3 days Rainsense turned on the wiper for 1 swipe each time, screwing up a perfectly nice clean windshield.
Will the car quit running or anything?

Why "pull the plug"?

From the Owners Manual:

Rainsense™ Wipers
Vehicles with Rainsense windshield wipers, have a
moisture sensor for this feature mounted on the interior
side of the windshield behind the rear view mirror. This
sensor automatically operates the wipers by monitoring
the amount of moisture build-up on the windshield. Wipes
occur as needed to clear the windshield depending on
driving conditions and the sensitivity setting. In light rain
or snow, fewer wipes will occur. In heavy rain or snow,
wipes occur more frequently. If the system is left on for
long periods of time, occasional wipes may occur without
any moisture on the windshield. This is normal and
indicates that the Rainsense system is activated.
The wiper control should be left in the off position,
unless the wiper is needed.
The Rainsense system is sensitive to vibration and
can activate if something hits the windshield or if the
vehicle hits a bump.

Why "pull the plug"?

He just told you why. They operate when they shouldnt and it dirties a perfectly clean and dry window. Pulling a fuse or turning a setting to 'OFF' would stop this from happening...

This is why I am glad the '11V does not have this feature. A friend had a DTS with rainsense and it drove him nuts.

I agree. They should not cycle through when they are turned OFF, which is what the manual suggests doing. A simple flick of the wiper stalk and they are off, along with the advisement in the DIC that the RainSense are deactivated.

To pull the plug (remove the fuse... if there is one) seemed a bit extreme to me.

To each their own. I love them on those days when I'm in and out of misty or spotty light rain.
And yes... I use RainX also.

When I was looking at 11 leftovers in august, I asked whats different for 12? Sales guy said oh rain sense is back, I said oh great I definetely want an 11, I HATE rain sense on my suburban...

To pull the plug (remove the fuse... if there is one) seemed a bit extreme to me.To be honest, when I said pull a fuse, I wasnt paraphrasing the OP. When he said 'pull the plug', I assumed he simply meant he wanted to get rid of it in general.

On the 1st gens, pulling the fuse was a good way to get the headlight washers to stop working. I always had streaks of white down my paint until I did that.

Oops, my bad. Bad selection of words. When I phrased "I'm about ready to pull the plug" I merely meant to deactivate them. Sorry to have confused anybody. It is a rather annoying condition, and even on a spotlessly clean windshield, even one pass of the wipers will streak the windshield enough to make it aggravating when heading into the sun.
Many thanks for the info. When you deactivate rainsense system, you also automatically deactivate the system that turns on the lights within 7 seconds during rain for safety.

Do you get a "Rainsense Activated" warning in the DIC when you 1st start up the car?

I am like Trapspeed, I leave the switch on the wiper stalk in the "off" position when it is not raining and have never had a problem. I have an '09 CTS-V with the Rainsense wipers and I love them. My wife's '08 DTS has them too and she likes them also. No problems in either case. And the answer to Gary Wells is, no message in the DIC with Rainsense turned off. If Rainsense is turned off on the wiper stalk and you are getting a "Rainsense activated" on start up, then you have a problem.

I am certain that the wiper stalk is turned off, but I will check it in the AM.

OK, thanks, guys. All well now. I did not have the wiper stalk in the "off" position, but the next position up. Many thanks again.

Oops, my bad, wrong forum.

All kidding aside, Jim, at my age I'm happy if I can even find my "stalk", let alone tell what position it's in.

That's awesome...

Should I blush?
All kidding aside, Jim, if I feel my feet touch the floor in the AM I'm a pretty happy camper.
It's either that or a buck a pop via a Viagra just to see if it is still there.

I thought I would turn this thread back to the good siode. :)

One of the things I regret about my 11 coupe is no rainsense. It worked just fine in my 09 sedan and I miss it now. I didn't notice any difference in the size of the stalk from one car to the other, just the capability.

Now that I know a little more about how it works, and the fact that I did not know that the windshield wiper stalk had been bumped up 1 notch, thus engaging the Rainsense where it had not been engaged before, I am sure that I will enjoy it from here on out down the road. Many thanks again for everybody's input.

I do wish the Rainsense was calibrated differently as I only use it at it's least sensitive setting. Go anything over the least sensitive and it wipes too fast. BUT, that first setting is about perfect to me anyway so I still really, really like it...

I'm with vade_R, I have had it a couple of times on my Caddy's and just loved it, no more constantly playing with the delay sw. I was really disappointed when I couldn't get them on my "11" Coupe.
