The good: the outside temp gauge measures the temp correctly/accuately and illuminates when the headlights/park lights are off.



The bad: the gauge goes blank (no longer illuminated) when I rotate the headlight switch to any position other than OFF. <img src="/forum/images/smilies/968/sad.gif" class="smilie" alt="" />



Any ideas?



Thanks

Funny, mine goes from bright to dim when i plug/unplug the cigarette lighter. I'm thinking that there is a bad connection on the back side. I don't know how to take off the trim pieces (haven't really looked yet). Have you looked at the wire connection on the back of the temp gauge? I'm assuming the connections use crappy PVC terminals or something that can vibrate off of a wire.

Nope, haven't tried or removed anything just yet. I'm hoping this is going to be one of those "D-oh" moments when someone chimes in with the oh-so-simple answer.



Still waiting though...



I know Flash has experienced this one... come on Flash...

This summer the light stopped working (temp worked) on mine and when I tested it I found no voltage to the bulb (failed PCB?), I took the light from the cig lighter and stuck it in the temp gauge; it has no light with out the parkings lights but until I get a replacment it works for me (more of a toy really).

Mine defaults to Celsiuses, when I push the buttom I get Fahrenheit.

After about 30 seconds it goes back to Celsiuses.



Both scales are accurate.

That's odd. Mine stays at what ever it was on before turning the key off. It only defaults to C if I pull the battery.

Mine is stuck permanently on celcius, and doesn't respond to my pushing the button.

Mine displays the correct temp in the correct fashion (C or F) but the light went out very recently. Bummer.

Mine light goes on and off randomly. Seems to be affected by plugging things into the cigarette lighter. IMO it is not wortjh tearing the dash apart. If I need a temperature reading I stick my head out the window. It will just be one of those idiosyncrasies that is part of my car's DNA.

Ahh, the old fashioned method still works. <img src="/forum/images/smilies/968/wink.gif" class="smilie" alt="" />

Thanks for all of your inputs. Seems like if you have a temp gauge that still works, you're among the few.



Is the temp gauge good for anything other than reading the temp? In other words, is it a clock or timer or ???



Maybe the hole it's occupying right now could be better used for something else cool like......... I don't know what... maybe an eject button or something.



Any ideas?

The gauge does nothing other than provide the outside temperature - which it gets from a sensor mounted on the underside of the housing of the passenger outside rearview mirror. Knock wood, mine still works, and lights, just as it's supposed to. Someone, though, years ago scratched the readout so it's not as pretty as it should be - which I won't worry about until I enter concours events, which is never going to happen.

You could put a 944 clock and timer there (a down grade?)



I have seen people with turbo cars put a/f LED readouts and LED knock counters there.

i've seen an AFM that fits there - not very accurate though

I kind of like having the outside temperature displayed, though I wish mine would switch back to farenheit, with the option of viewing in celcius when I want it. I seem to rememebr there was a fix for the "stuck on celcius" problem, but I can't remember what it is. I'll do a search, but in the meantime, does anybody remembr the fix? I think it had something to do with one of the fuses, or something in or near the fuse box...

The unit is very easy to remove by first removing the horizontal trim strip. Start with the passenger door open and remove the triangular plate on the side that you will see held on by a few screws. Then just follow your eyes. It all gets removed from outer side working to the centre. Be careful of the cover to the interior temp sensor hole (it twists 90 degrees on a bayonet) and there is also a screw in there. The knobs on the sliders for upper and low air distribution just pull off. Be careful not to break the tabs. These won't go back on if the tabs break. The rotary knobs don't need to come off so don't try. Once this is all off (5 minutes) the temp gauge just comes out. The connections and bulb are easy to access although the fingers take a bit of a beating doing it until you are familiar with the routine. OJ would be convicted with the blood I have left in there. I have done this a dozen times fixing dash stuff. The bulb works full power when the lights are out and half power otherwise. Probably if the bulb is on when the lights are out you simply have a dirty connection. Good luck.

Wow, great write up Kim, thanks! When you say "dirty connection", do you mean at the bulb itself or are you talking about the light switch rotary knob?
