Alex Posted January 22, 2002 Share Posted January 22, 2002 Has anyone else found that their fan speed and heat dials don't light up properly... mine don't come on unless its bitterly cold....guess the contact is bad and as soon as it gets warm it flexes away to break the connection.

FaithStalker Posted January 22, 2002 Share Posted January 22, 2002 err - these are on the dash?!?! mine has never come up EVER ! ===edit=== stupid me - forget i posted it!!!!!! i thought you were talking about engine fans etc. mine light up fine (Edited by ajefford at 10:53 am on Jan. 22, 2002) Link to comment Share on other sites More sharing options...
Digsy Posted January 22, 2002 Share Posted January 22, 2002 Hi Alex, I take it you are talking about the backlighting and not the green LEDs? My temp. dial and fan dial do not light up at all (LEDs work OK thought). In fact I have been meaning to start a thread on exactly which dials and switches are meant to be backlit, because not many of mine are. Link to comment Share on other sites More sharing options...
THOR Racing Posted January 22, 2002 Share Posted January 22, 2002 This may upset a few people but they are ALL backlit when you turn the lights on. The LED's obvioulsly indicate which air-flow setting you have and what fan speed etc but the two rotary dials have backlit illumination and so do ALL the buttons!!! You're meant to be able to see them in the dark to make your choice easier ;-) rather than guesswork. They are little filament bulbs inside the unit so yours must all be broken. Toyota sell these for about £3 ish (don't quote me) each. Also don't ask for the part number as I don't have it. Take it apart and take the bulbs along to them. I actually replaced one members bulbs with RED LED's as he wanted a RED dash to match his red car, illumination was difficult due to the narrow angle of light from a LED verses the wide angle light from a filament bulb. But it was sorted eventually by high intensity LED's and a clever piece of tin foil to reflect the light around inside. Regards Pete Link to comment Share on other sites More sharing options...
Ian C Posted January 22, 2002 Share Posted January 22, 2002 This explains why I can't see my temperature and fan speed dials too well in the dark! Blimey. I have to replace one of the clips on the dash trim, and fit my nice Rio 10Gb MP3 player head unit (:biggrin:) at some point so I'll sort this out as well... -Ian Link to comment Share on other sites More sharing options...
Digsy Posted January 22, 2002 Share Posted January 22, 2002 Cheers for the reply Pete (sorry to hijack the thread Alex). What about the dash illumination level knob on the dash and the door lock and window lock switches on the driver's side door panel? Should those illuminate too? Mine don't...

Alex Posted January 22, 2002 Author Share Posted January 22, 2002 I only have a problem with the back light to the two knob controls. And like I say when the weather is very cold they work fine! Link to comment Share on other sites More sharing options...
THOR Racing Posted January 22, 2002 Share Posted January 22, 2002 Multiple replies.... Alex >I only have a problem with the back light to the two knob controls. >And like I say when the weather is very cold they work fine! Sounds like a simple connection problem with your bulbs, also the bulbs for the rotary dials are connected to the main PCB by a small connector plug. I'd take it apart and remove all connectors and bulbs and then clean any contacts with a bit of emry paper or something (careful not to rub the PCB tracks!) and refit. That should sort you out. Darren, >What about the dash illumination level knob on the dash and the >door lock and window lock switches on the driver's side door panel? >Should those illuminate too? Mine don't... Haven't noticed my illumination knob lighting up so I can't answer that one. The door panel switches should light up , I think these are LEDs though. Never had call to remove them as they didn't go wrong. Sorry Regards Pete Link to comment Share on other sites More sharing options...
Matt Harwood Posted January 22, 2002 Share Posted January 22, 2002 Illumination knob does not illuminate, I had it apart recently to clean the internals and theres no bulb, just a variable pot. Although if it's disconnected nothing illuminates! I only have the drivers window switch illuminated in my drivers door. Are the othersin the drivers door and the passenger door window switch meant to also? (Edited by Matt Harwood at 3:32 pm on Jan. 22, 2002) Link to comment Share on other sites More sharing options...

lust2luv Posted January 22, 2002 Share Posted January 22, 2002 From memory, I'm pretty sure only the driver's window switch illuminates (unless of course mine has the same prob as yours). My ashtray has a nice little light in it though! (or shouldn't I mention that! ) Link to comment Share on other sites More sharing options...
Flipfinger Posted January 22, 2002 Share Posted January 22, 2002 Yeah, definitely it's only the drivers side window switch that lights up, you can see the LED in daylight. Link to comment Share on other sites More sharing options...
Matt Harwood Posted January 22, 2002 Share Posted January 22, 2002 Good, glad my lights all work... I also have an ashtray light and a glovebox light! (lower glovebox only though ) Link to comment Share on other sites More sharing options...
Guest Martin F Posted January 22, 2002 Share Posted January 22, 2002 Quote: from Alex Holdroyd on 12:23 pm on Jan. 22, 2002[br]I only have a problem with the back light to the two knob controls. And like I say when the weather is very cold they work fine! I also had this problem, pulled out the heater switch assembly and couldn't find anything wrong with it. Turned out to be the connection at the other end into the A/C amplifier was very loose. It sits on top of your stereo along with another box (the antenna relay i think).

Simon Posted January 22, 2002 Share Posted January 22, 2002 On mine, the backlight to the fan speed only illuminates brightly as the fan kicks in (I always have it on auto) , the temperature backlight also appears to work the same way. So, if the temperature is right then both lights are dim/off, if I force a temperature change (open windows for a period of time) then when the system is set to auto the fan will kick in to re establish the set temperature. The lights then illuminate brightly until it's all stabalised again. Link to comment Share on other sites More sharing options...
Digsy Posted January 23, 2002 Share Posted January 23, 2002 I don' t know what the hell made me think my temp dials didn't illuminate, because they do! My driver's side window switch is the only illuminated one in the door panel, so it looks like this is normal as well. (Even my ashtray light works).

Ian C Posted January 24, 2002 Share Posted January 24, 2002 I'll tell you what made you think they didn't, because *I* didn't think mine did either, and they bloody do. It's the poxy little marker on the knob itself that shows what temperature you have chosen - *that* doesn't light up, and it's very very hard to see at night, despite the actual tempereature grading being illuminated. So because the marker doesn't light up, we can't see what temperature is set, ergo our brains record the temperature knob as being unlit because it's hard to see at night. Sound plausible? -Ian Link to comment Share on other sites More sharing options...

Matt Harwood Posted January 25, 2002 Share Posted January 25, 2002 Sorry to throw a spanner in the works here, but the little marker on my temp knob lights up. not very bright but it's definately there. Link to comment Share on other sites More sharing options...
Ian C Posted January 25, 2002 Share Posted January 25, 2002 Aye, it's got some sort of phosphorescence (Jaysus - anyone want to check the spelling on that?!) but no backlighting. It isn't bright enough in my book... -Ian Link to comment Share on other sites More sharing options...

jackso11 Posted October 26, 2005 Share Posted October 26, 2005 ok....bit of an old thread but very good. One question.....where is the illumination dial! I just got my supra and did think it was strange there was no illumination dial as Jap cars usually have them. Last car was a mazda, thats what why I thought of it.....its not a function I usually look for! Link to comment Share on other sites More sharing options...

I just got my supra and did think it was strange there was no illumination dial as Jap cars usually have them. Last car was a mazda, thats what why I thought of it.....its not a function I usually look for! its near where you put your key in. turn it clockwise/anticlock wise dim/bright. if the ickle bulbs need replacing this will show you how to dismantle the dash. http://www.mkiv.com/techarticles/boostguage/bg.htm Link to comment Share on other sites More sharing options...
