Climate Control Sunlight Sensor - Auto Headlight Sensor

[101RRS]

Two newbie type questions for the RRS/D3.

1. I assume the little dome next to the subwoofer on the dash is the sunlight sensor for the climate control. Yes/No? If it is, I have a dash cover which covers over the sensor and a friend said that the climate control will not be turning itself up and down with exposure to sunlight. Ie - turns itself down when there is no sunlight (heat) coming into the car and likewise turns itself up when there is heat from the sun (is in addition to temp sensors).

So is this correct and if so do I need to cut a small hole in the dash cover to let the sunlight in? The climate control does seem to work OK with the dah cover in place.

2. I also assume the sensor for the auto on for the headlamps is the sensor I can see in the headlights. I also assume there is some other triggering sensor somewhere. The reason I ask is that on occasion the lights have not come on until really dark yet on the weekend I was driving directly into the sun just before sunset and the lights stayed on even though the headlight sensor had a direct line to a very bright setting sun.

Can someone enlighten me on the magic of these things.

Oh - the wipers come on even when a big bug gets smashed on the windscreen - where is the sensor for detecting squashed bugs.

Cheers

theres no sub in the dash (its in the rear door(if fitted)) ,, theres nuthen under that cover,, id cut a hole in it , its there for a reasion i guess;),,

the headlights and wipers are in the mount for the center mirror, look from out side in and youl see em,

Ok - thanks for that.

So what is the square fitting on top of the dash (up near the windscreen) with the little bubble on one corner (it is this that I assumed was the sunlight sensor).

Looking at the rear view mirror from the outside there is a small square sensor - is this for the mirror itself (to tell it when it is dark) or is this foir the lights? What is the small bulb in each of the front parking lights - next to the light bulb is a bulb that looks like a sensor.

Isn't that's the door key sensor ? It's on the left side
on many marques as is the mechanical door lock option , for the US and European markets ( where the sales are ......... ).

[101RRS]

I wouldn't have thought so - but what do I know:( - hence my dumb questions.

It would seem though a lot of people are in a similar boat though.

I think it is the door sensor, as in doors open, security off! (on the dash).

Have driven a Sierra in the UK and Jags and I'm certain they had a similar set up.

Just had a dumb ass idea and tried to cover it....but it's RF, so short of a lead cover, that won't work....:(

I guess the grill is for a speaker if you bought the 16 speaker system....maybe.....:confused:

Which door is the Sub-woofer in Stig, the hatches or one of the passenger doors?

LOL, here we go,, the lil dome thingy on the panel at the center dash is the sun sens, the 2 domes eather side in your headlights is just a dumy as you dont have HID with cornering lights,

the sub is in the rear boot door its self, (on the l.h.s if you realy wanted to no), you only get that on the logic7 and harrmen kardon sound sys,,,

oh and the centul locking is mounted in the middle of the head lining bolted to the roof,

what i forget, oh the rear mirror dip is a tiny lil sensor in the middle of the mirror, anything elce :p

[Celtoid]

Oops, guess not then on the dash thingy...LOL!!!

And yes the fake bulbs in the front light cluster....had me guessing for a while....read.....driving around in campsites in the dark....hard turns, blinkers on (like the Nissan idea)...different speeds and angles....LOL!!! Bloody LR :oops2:

Actually Stig.....another Q...I have the logic 7.....where are all of the 9 speakers located? Some are obvious in doors etc, but they don't add up to 9. Now I know where the sub is...thanks.

Are the speakers on the door pillars for the phone only or are they part of the system....conversely, does the phone use all the speakers when activated?

Thanks mate. Appreciate it.

Cheers,

Kev.

Maybe it was only 6...?

Thanks Stiggy - I have my etag mounted just in front of the front sensor of the rear vision mirror but doesn't seem to cause any issues.

What you haven't answered yet is where is the water sensor for the wipers?

I have the standard 6 stacker audio system but it does have a sub woofer setting so I assumed there was one somewhere.

So the dash sensor is the sunlight sensor for the climate control? and the front square sensor on the rear vision mirror is for the headlights??

The rain sensor & headlight sensor are the same unit.

[101RRS]

The rain sensor & headlight sensor are the same unit.

Well if it is inside the car on the front of the rear vision mirror - how does it detect the rain (or squashed bugs)?

Light refraction I believe.


Hmmmm - white man's magic :o

Hi Garrycol,

The attached pics should answer all your questions...

It's handy having the workshop manual:-)

Col,

Thats great - thanks. While my dash cover has a little bump in it to allow for the sunlight sensor it is nevertheless still covers it - maybe I need to cut the bump out so that the sensor can once again see sunlight - though it does not seem to make any difference.

[stig0000]

there are 2 speakers in each door, and if you got the L7 there are 2 more speakers up in the roof at the back, the fone gose thru the front speakers, ,, the park addes have there own speakers,

soz if it wasent clear but the head light and wiper sensors are both in that square pack on the windscreen, its simple sys of it looks at a reflection from the window and if that reflection is broken it wipes, allso if its contently broken it goses faster same as if you speed up it wipes faster,

next :p

And the sensor is part of the windscreen, not the rear view mirror. Having had a new windscreen in mine recently (and now in need of another one) I remember looking at it as the fitter unclipped the mirror to fit to the new screen.

Hi Garrycol,

the manual say;

The sunlight sensor consists of two photoelectric cells
that provide the ATCM with inputs of light intensity, one
as sensed coming from the left of the vehicle and one as
sensed coming from the right. The inputs are a measure
of the solar heating effect on vehicle occupants, and are
used by the ATCM to adjust blower speed, temperature
and distribution to improve comfort. The sensor is
installed in the center of the fascia upper surface and is
powered by a 5V feed from the ATCM.

the ATCM is Automatic Temperature Control Module (the heating head unit in the dash)

So your Temperature control being hidden is working but not effectively and not receiving info to adjust the blower speed.

I'd be cutting a hole in your cover to let the sunlight in:-)

Thems my thoughts too - thanks for the information you have put up - very helpful.
