A few days ago I got into the car and on switching on the ignition my speedo sat at zero flickering rapidly. It then ceased to work but a few minutes later was fine.
Today, I find the speedo nor the rev counter works, they just sit there. I'm thinking a loose connection on the multiplug, have tried to press the clocks back and tapped the dash top to no effect.
The ABS and TC lights are NOT on
Any ideas?
Thanks

dash out i guess. Guide in maintenance as im sure you know. My old cdx had a dicky moment once but only after i had removed it to change a dash bulb. The tape/circuit board was very close to not lining up the with the pins on the plug. Should be able to see the pin marks on the tape. In my case just re seating sorted it. Failing that...?
-
I had the same problem a while back, various theories put forward but basically it's most likely component failure in the cluster. Or just push the dash in hard and hope it's a dodgy connection!
My tale:

The dash is well easy to get out, once the vents are prized off anyway, but what i've found so far is that dash's from 1996 cars don't seem to want to work with a 1999 one. :(

Thanks fellas
Will pull the dash out tomorrow. Give that a go, if not will try to source another clocks unit. Am I correct in thinking the proper mileage can be programmed into the new clocks using a Tech 2?

It's not an electronic dash unit so there is no need for a tech 2 you can do it yourself :y

And how do you diy?
But if it's not electronic, how come there's no cables coming from it, just that connector thingy - which looks electronic to me! :-/
-
Well I've pulled it out today, tried to clean up the contacts as well but nothing. Still sits there flickering so assuming the clocks are dead.
Just realised I cannot post a Wanted ad in said section either, don't have enough posts :-/

PM Markey Mark, he breaks Omegas for breakfast ;D
He should have a V6 dash, remember 4pot dashes are not suitable.

Check your fuses as well! If I remember correctly with mine when this failure occurred, it was either No 12 or 19 fuse that had blown. Yours may have worked loose, hence the earlier flickering. ;) ;)

I think he means the actual odometer bit. The odometer is the old fashioned numbers on a mechanical barrel rather than LCD display eg Astra G. Digital can be Tech II'd for 'milage correction' ....... ::)

Thanks Lizzie, alas it is not. They are both fine. The needle flickers constantly with ignition on now. Only after it is switched off and you wait 10secs does it stop, and then it doesn't return to zero, stops around 5mph.
Thanks tunnie, will do so now.

That is what I meant yes :y
-
So does it need Tech 2 or can it be done by other means?

Other means :)

Dare I ask how?

Dare I ask how?
small screw drivers to dismantle the speedo/odometer and 'adjust' as necessary ::) ;D ;D

Exactly that :y

Ok thanks! Just need to source some clocks now.

Well this morning all worked ok. This afternoon, nothing. Went to scrappy and picked up a set, dismantled them and tried to adjust mileage (not knowing exactly how) and managed to pull a fine wire from its solder so doubt these will work now either.
Big dirty great engines am ok with, small fiddly electronics not so good. So back to square 1. I'm just not happy with having clocks in that show the wrong mileage. Am a perfectionist really with cars :D :-[

I'd have just tried the 'new clocks' for a few days to check that yor old clocks were the actual problem. You could always look into 'correcting' your milage at another time.
-
A valid point, one which I overlooked :-[
Good news though, just in case, I swapped the PCB's inside the clocks over; using my clocks with the correct mileage and the board from the donor clocks and now all works fine. Unfortunately though due to it getting dark now, as I was putting the clocks back in I managed to loose two of my screwdriver bits in the bowels. Will have to look for them when it's light.
Shall also look at the climate bulbs then too.

Well all was well until I came to start up to come home from work. Rev counter dead, speedo flickering again. Now I'm wondering if its the clocks or not.
Any ideas?
-
A bit of thinking leads me to suspect the crank sensor. Is this possible? Does the speedo take its info from the crank sensor? The needle does flicker 'in time' with the engine as it were.
Crank sensor price if it could be this?
-
Anyone confirm or think what else it could be?
-
Checked fuses and relays?
-
Yep, all checked, all seem fine. Was working again this morning, has become intermittant now.
-
Right, to complicate matters it seems I now have a flat battery whenever I go to the car. I can't help thinking the problems are related. I know a voltage issue COULD cause the speedo problem. Trying to source a multimeter (mine broke) so I can do some testing.
In the meantime. Any ideas?
-
Battery showed 10V static. When engine on, 13.7V but never dipping below 13V even with headlights etc switched on.
Am I to assume the battery has had it?
-
Alternator, that was my problem, new one and sorted.. :y
-
My non working rev counter and fluttery speedo was fixed today :y after months of relying on tomtom for speeds!
how?
by replacing the clocks. straight swap from another 2.0 '99. :y
worth finding another set from a near identical model to your own to try the swap without tinkering.
I've just lost 60k off me tacho, but in a fortnight if all's still well I'll look into the adjustment!
