Hi

I have a yeti that has a rain sensor fitted behind the rear view mirror.

However there is no where to activate it on the wiper stalk.

How can I turn it on?

Model : outdoor se TDI CT

 

Thanks

There should be a sensitivity slider on the top of the wiper arm. The wiper needs to be in position "1" (position "0" being off.) for it to work. Then sensitivity can then be adjusted using the slider.

Thanks I'll give it a go

Do you there is a slider on the exterior wiper arm?

Hi Graham and welcome.

 

Sensitivity slider is on top of the wiper control arm (i.e. the "stalk" referred to in your original post).

I do believe the lights have to be in Auto too.

Thank you, Urrell.   To date I've been underwhelmed by the performance of the rain-sensing wipers with lights in the "Off" position.   I'll give "Auto" a try next time it rains.

..I am sure mine work OK without the lights being on auto?...

Just tried mine, I thought they worked manually without the lights being in auto but they don't.

The automatic rain sensing wipers work irrespective of the headlight switch position.

 

The only connection between the wipers and headlights is when the light switch is in the 'Auto' position, the headlights will turn on after the wipers have been in continuous operation for more than 30 seconds.

There is no logic that I can think of for the auto rain sensors to only work when the lights are on auto?....I rarely have my lights on auto and I regularly use the wipers on auto?

Are you sure your Yeti has the automatic windscreen wipers feature?

 

Even though the sensor is fitted, the feature might not be active. Some models utilise the same sensor for multiple features, such as the light sensor to operate the automatic headlight control.

 

Did the Outdoor SE get the rain sensor wipers as standard?

 

If not, then the first position up from 'off' on the wiper stalk will operate as a regular 'intermittent' mode, the slider switch on top of the stalk simply alters the time in-between the intermittent operation.

I'm pretty sure that the ran sensor and the light sensor are separate, or at least function separately.  My understanding is that the rain sensor works on the principle of total internal reflection (effectively, how much light is reflected or transmitted through the glass).  I once had the windscreen replaced in an Audi A1 with the same lights/wipers setup as the Yeti - afterwards the auto wipers wouldn't work at all (but auto lights were fine).  It turns out that the fitter had forgotten to fit a gel pad into the rain sensor - once a new one was fitted it all worked fine.

 

And also, the presence of a slider on top of the wiper arm surely doesn't confirm auto wipers are fitted?  The same slider is used on non-auto wipers to control the interval setting for intermittent wipe, no?

 

Back to the OP - there is no 'auto' setting per se, there is just the intermittent setting.  On a car with auto wipers, the interval is automatically adjusted (and only automatically adjusted - there is no way of setting a periodic interval).  If you flick the wiper stalk up one on a dry day and the wipers do not wipe regularly, then you either have auto wipers, or a faulty manual setup!

 

Auto wipers is a must-have for me on any car; I've had it on various cars (Ford, BMW, Audi, Skoda, Volvo, SEAT) and it has always worked fine.  You need to sometimes manage it a bit (like in very fine spray) but for the most part it works away unnoticeably in the background.

Doesn’t the rain sensor also allow  automatic closure of the windows and sunroof if car is parked with them open?

What is the interval wipe on manual wipers is the sensitivity adjustment on auto wipers.

I don't think you need a rain sensor for the remote closing to work.

You do if you mean auto-closing if it rains. Mine also closes the blind on the sunroof if I've left it open.

there must be a sensor that detects the rain to activate the closure of sunroof and windows.i thought this was a very good system,also if the car is locked after a certain time it closes the sunroof blind.

They share the same window on the windscreen though. The OP mentioned he had a rain sensor, I was asking if he was sure. Just because the aperture is there doesn't necessarily mean the rain sensor is behind it. There might only be the light sensor for the headlights.

 

We need the OP to answer some of the questions.

 Well well well, I didn't know that such a system even existed! I don't have a sunroof, but I do have windows, so I'll test it next rainy day.

Make the most of it, its a neat feature that is now disappearing from the latest models (Superb MkIII), something to do with a new type of sensor.

I have "automatic" wipers with my car. They aren't truly automatic of course if you have to have a slider/switch that needs moving now and again which I have to do on occasions!

If you leave the wipers in Auto mode, then each time you restart the engine you need to 'activate' them to get them to work again i.e. adjust the sensitivity toggle, or turn them off and back on.

 

This prevents them from turning on as soon as the ignition is turned on if the windscreen is wet, especially useful if the screen is covered in snow, or if the wiper blades are frozen to the windscreen.

I have never had to reactivate them.

Yes it does.
