Hi guys, I went to car wash today than gave miggy a nice interior cleaning at home and suddenly speedometer isn't working anymore, the same with rpm gauge. No TC/ABS light on, all the other dash lights and gauges working normaly. I tried to push cluster panel , no result. Is there anything else I can try or is it FUBAR? :-[
Thanks in advance, Stan

I've experienced this problem in the past, you somehow must have blown a fuse, dont know which number but its a 20amp fuse in the middle row :y

And a light bulb in the cluster is blown, thanks Stallion , I've just checked fuses - all seem to be fine :-\
-
I've checked all the fuses again with volt meter - all fine, so I took cluster out, reseated back - with no result. Rpm needle is moving a mm up and down when I turn key to contact and continues movement all the time even if I drive. Speedo is completely dead. I took a video of cold start, waiting to be uploaded :'(

Double and treble check F12. Failing that, check connector mounting behind instruments isn't damaged, stopping unit fully seating.
-
I tripple chedked fuses from 11 to 15 especially :-\ and the connector behind the panel is ok, gave it a good clean with contact spray an on the cluster itself also :'(

Searched german ebay for replacement without any luck. There's car electronic garge near me I'm going to show there tomorrow to see if they can fix it - and the price
-
Cluster could be toast :(
-
I'm afraid yes, but I hope it can be repaired.
-
Or even better, well it depends...Been searching on web and it seems it's quite common for GM cluster stepper motors to fail. So I'm thinkinh about taking the cluster appart, write down the stepper motors numbers and find those on ebay. If it happens (IF) to save the problem I will post pics and procedure. Fortune favours the brave :P

I disassebled instrument cluster today, found two motors inside - part number 91 255 002 65 for rpm and 91 255 003 for speedo.
So I made a call to main dealer just to be told that only entire speedo/rpm unit can be ordered for 230eur :o
Before I try to find those stepper motors on ebay, does anyone know if stepper motors are the same across the range? Old working instrument panel from PFL/MFL can be easily found here for as little as 15eur....I'm thinking of replacing mine with used
-
Ideally you want one from the same body/engine/gearbox otherwise the fuel gauge/rev counter/speedo will.all.be wrong...
Engine is most critical, followed by gearbox then fuel gauge.
V6/4cyl/diesel not interchangeable.
Gear ratios vary according to engine AND gearbox
Estates have a larger fuel tank, so a Saloon gauge in an estate will under read and vice versa.
:y
-
Can't get the same model anywhere - went even german ebay....that's when I got the idea of replacing motors only. I really hoped at least stepper motors would be interchangable :'(
-
They might well be... Certainly worth a punt :y
-
Guess what guys!!! I fixed it :y ;D :D ;)
For all those who have the same problem with rpm/speedo clocks....take instrument panel out, take it apart and resolder every connection to faulty stepper motors :y
Damn I'm happy ;D

It'alive :D ;D

Great result :y
-
I guessed it wouldn't mind anyone of I borrow this topic as the problem is almost the same.
So rpm gauge holding it's place, speedo wigling around zero. Steppers soldered, every single fuse checked, even relays, paperclip test only 31 came, cleaned everything as i was installing the dash, took off battery, and thinking everything that could cause it but im hopeless now... :-\ Help meee

My rpm/speedo gaige stopped working some two weeks after I managed to bring it up from the dead by resoldering evrything so I ended up with buying replacement from ebay.de.
70€ postage incl. Has to be same model/same engine/same transmission AFAIK

Okay, thanks for the info :y
Shame that it can't be worked out any other way :-\

EDIT1. Does it matter if i have 3.0 but replacement 2.5?
-
As far as I can remember it doesn't matter (from searching forum) , it needs to be from same model/same transmission - as long as it's V6

Glad you fixed it , now dont wash it again ;D :P :P
-
The problem solved by itself the other morning..... Can't understand what is wrong there somewhere :-\ :-\
-
It was the same wih mine. You'll see - a few cranks later it won't work anymore. There's no visible damage on solder joints, nothing at all. A local electric shop said they can fix it for 100€, but I went for a good used one. Still kepping the old one in garage though, just in case :-X
-
Is it a manual gearbox? I have a spare instrument cluster off V324DTO, a 2.5 petrol manual V6 2.5 Omega saloon that I scrapped last summer. Speedo has MPH in main calibration, though KPH below and smaller. Any use?

Congratulations!
Forget the above silly offer, I was stuck on page one. I used to mend electronics by thus soldering dry joints for years, especially on car components, but I thought it had gone out of fashion. I have mended ECUs that way on Citroens and Peugeots, but on Omegas I have been advised that Omega ECUs are bullet proof, and so it has proved. Not so on other components apparently.
