Waht does this do ?

[scooby_doo_do]

Does anyone know what the little black Dome looking lump thing does inside the car just before you reach the windscreen ? (Sorry about the description!). Is it something to do with the standered alarm ? Or is it a gprs system for aliens because they all want supra's to fly around space in.. (Sorry for the last bit :-) )

It's a solar sensor for the A\C system.

Its a mini trackball for the in-car Atari system. All imports have them, doesn't yours?

[scooby_doo_do]

I must of had an upgrade option on mine... I got a commodor with the nice green screen...

What does the solar sensor do?

and don't just say "senses the sun" like you were going to.....

[Martin F]

It senses........................ :baa:

On hot days when it is particularly sunny (so not in the UK then) it causes the A\C to increase output slightly to compensate for the heating effect from the sun. Hence the reason why it is at the front of the windscreen.

And there was me thinking my car was special, i didnt ask about it because i knew everyone would want one, darn it now it looks like everybody had one all the time.

well I think its crap .. coz my A/C doesnt work . .never has ..and never will . . but really I'm making excuses for being an Essex boy coz I love driving with the windows down with my arm dangling outta the window !!!!!

Have you tried some AC diagnostic codes????

[sky]

well . .this was the situation Mr T !

When i bought the supe . .i was told the gas was low . .so I go Toyota Citygate (slough) to check out the level and also a general check to see if it worked . .it came back all clear . .but when I got it back it was the same . .I took it back and they said that its different on every car or some bullshit like that . . I had someone else take a peek at it but no result . . so .. what do you advise I do chap ?

is this the sensor that also detects whether it's daylight ?
since when it's dark if you pull on the door handles it the interior lights go on - as doe the lights around the door and ingition key holes !

[Terminator]

You can do some checks your self, I can email you the checking charts for codes, but I can't remember which two heater/air con buttons you press to get diagnostic at the moment, I am sure some one else will beat me to it.

Most main dealers know very little aabout aircon specialist firm is the best way to go once you know what is wrong with it.

Errr as far as i know that happens whether it's day or night, it's just not so easy to see during the day.

Correct. Strangely, the keyhole on the door does not illuminate on facelilt cars.
