Hi

Just got my IS200 a few weeks ago and just getting used to it as well as looking in to what I can change / improve.

Before I had a mk4 golf which I added auto wipers too. was a simple case of add the rain sensor and change the control relay.

now the rain is on its way again, wanted to know if auto wipers could be added to the IS as I am finding the timings on the int wiper dont always suit and I kind of forget to turn them off when the rain drops off.

On a maybe related note, what are the sesnors on the dash for? I assume one of them is for the auto lights (liking this BTW) but what is the other for?

Thanks

I have a few other questions planned but still checking the search button.

other sensor, is for the solar sensor, to determine functions of the Aircon and climate system.

regards adding rain sensors, no mk1 is200 was fitted with them so, its not something that could be retrospectively fitted.

if there was a kit, then it could be possible...but i dont know, i personally dont have any issues with the intermittent settings.

regards the auto headlights feature, leaving it switched on, can cause the relay to burn out, causing the lights to stay on all the time.

so, i would only switch it to auto, during a trip, but switch it off, on parking

I believe the other sensor is the same as on my GS, and is the solar sensor for the aircon. I always assumed the auto-wiper function on other cars is controlled by sensors on the [b]outside[/b] of the windscreen to detect moisture, so would be relatively easy to add. I could be wrong though.

the sensors for the auto wipers are on the inside of the window in the center and its incased in gel(thats why 9 times out of 10 when you replace the window you replace the sensor)

Does it just work on light levels?

handy info about auto lights.

solar sensor is different, guess it can guess how much the car will warm up before it does kind of thing.

I did find something on the search about a rain tracker, looks like this will be the only way just did not intergrate in that well as you have to turn it on/off with a toggle switch.

thanks anyway, will just have to adjust back to manual ones.
impress by everyones fast, helpful responses.

to be honest i don't know some people make out it senses dampness???and some say light levels but i really dont know ,but it has somthing to do with the gel because if you damage the gel in anyway the auto wipers stop working.

the rain sensors work on a disruption to light, as the rain droplet, will effect the light pattern received by the sensor, the heavier the rain the greater the disruption to the light received

Refraction and all that lark

indeed....

Yep it's light that makes them work - there are aftermarket kits that you could install but it was never a specific thing on the IS.

Interesting about the auto lights, I've had mine on permanently pretty much for the last 7 years - is it a long term thing or would it have happened already if it were to burn out?

from past cases they have normally started to fail by now, ....maybe it was rectified at some point by Lexus....

I'm touching some wood as we speak - knowing my luck it'll fail the next time I start the car now.......hopefully it was sorted out then

I have installed Rain Tracker on my Previa.works 100% .
Easy to install.

I've actually looked at that before but then wasn't sure whether to go ahead. When you say easy, how easy was it to install? And does it work well?

urm... details please.
did you use the 40A or 50A?
did you have to use thier on/off switch or could you build it in to the wiper arm mode i.e only works on the intermediate setting.

thanks

i'm not trying to offend anyone but is moving the wiper stalk too much hastle now adays??

I used the 50A.
I have connected in paralell with the cables to the wiper engine.
I also installed the on/off switch .
And the original switch works as before.
I was impressed by the way it worked.Almost perfect.
No need for adjusting or anything.


Nice thing to have here in Norway in these rainy days:)

Cheap to.
