Have the rain sensor but not the option.
Noticed the module on my windshield just to the left of the Lane departure camera (when looking from inside).
Wondered what the heck this is. It was relatively easy to disconnect, wrote down the p/n 113890-0031, it’s a rain sensor!
Problem is, my wiper control arm doesn’t show this as an option. My new 2018 NX300 awd is the base model (for Canada).
hmmmm... I guess another question for the dealer at the 1600km courtesy service appointment.

Does it have to show? Auto wipers work simply when wiper stalk is moved one click down from neutral. I really doubt Toyota will place sensor without any need for it. Toyota is KNOWN to be very lean manufacturing and that's waste.

I even poured some water on the windshield to see if the frequency changed, nope, work s like a regular intermittent wiper system.
It absolutely seems like a waste to attach a perfectly good rain sensor onto a vehicle that isn’t set up to use it.
It’s not like it ever was an option, we ordered the base NX300 model, the only options available were just your typical dealer add on accessories like BSM, hitch, door sill lights, etc.

If you have the rain sensor can you not purchase the replacement stalk? I would imagine it's all plug in. Then use TechStream to enable rain sensing wipers. I remember when I was looking through techsteam you could enable/disable the rain sensing wipers. But who knows... might be more to it than that. I'm sure others can chime in.

Might just be a techstream programming thing. I wonder if rain sensing is turned off (on those vehicles with it) does the system default to regular intermittent function?

Discovered some hints in another post, so it lead me to the owners manual, and presto,. Here’s the answer.
Humidity sensor, which is used when using Auto climate mode.

The Part# I discovered on it shows online that it’s used over several Toyota and Lexus models for the rain sensing wipers.
But, you would think that if they were installing at the factory for either the Auto Climate or Auto Wiper function (or both), why not just include both functions full time?

I checked my NX300 which has the Rain Sensor attachment compartment on the windshield (cannot see what is inside), but the wiper control arm doesn't mark rain senor choice. Anyone know how to make it work ? I will to pay a reasonable cost!

I had rain-sensing wipers on my 2008 IS, and they were terrible.Never again will I buy a car with them. They moved when there was no rain, and often didn't move when it was raining. They never operated at the correct speed, always faster or slower than what I would have chosen if I'f had intermittent wipers.
