97/98 saxo vts/vtr dials not working (speed rpm and fuel)
But when holding the key to start position everything works
Only the dials are not working. Lights etc work fine

Tried the unplugged battery trick for a couple of nights didnt work.

New ignition switch and same problem

I would check the earths and try a different set of clocks.

Had the same issue and was the clocks for me,got a new cluster and it was all good again.

Rather weird for it to be working while starting. Hard to find new clusters

I've checked the leftside A-pillar ground, scratched some paint off and checked the ring terminals, and added extra ground from the strut tower to the battery.

I'm thinking it might be a relay or something like that, because everything works when I have the key in the start position

Would a cluster from VF7S0KFXF56982621 fit to a VF7S0KFXF56484893
cheers

New dials fitted, not working still. Guys please any ideas

pyxq · 10th February 2023, 14:28

Could it be a relay in the footwell? There is a greeen and a yellow relay next to each other, yellow one is activating when starting the car, but the green one does nothing

sri_130 · 10th February 2023, 19:02

I didn't think the dials had a relay... I couldn't find one that was specific when I had problems on a 106.

Not for the dials, but there is something that has to do it, because how could they work when starter is in use and only then

Am I really gonna have to scrap a little bit over 60k gone car that 0 rust and paint in perfect order, just because of a electric fault

theres a few fuses in the glove box wihch are linked to the dials, remove and re-insert them with the ignition on. over time they get a tiny bit of corrosion on them and it causes this fault.

If you've changed the whole cluster, clearly there's a supply fault.

Well driver side for me, but yeah I've removed and checked and changed them plenty of times. Doesen't explain why dials work when starting tho

That's not what I said though, have you tried doing it with the ignition on? Specifically the bottom right fuse.

I see your fuel gauge acts strange, it's not like the power is being cut immediately. Is the battery voltage stable? It's not over-volting to over 16 volts ? That could maybe cause an issue.

It's clear the fault is in the wiring somewhere, since you've changed the cluster.

Voltages are stable and

I did try the taking out fuses with the ignition on, I took out every fuse and re inserted still not working. I found another post by saxoestonia or something along those lines who had the exactly same problem. But well did he tell what the problem was. of course not, Well I guess I will just have to go to try the mot, get 1 month of driving and then scrap it unless I find out a way to fix the dials even with a switch or something like that

pyxq · 18th February 2023, 15:49

Well i got a year more but would still be nice to have working clocks

MartinObviously · 20th February 2023, 21:57

Hmm, I'm wondering if there's a problem with one of the main relays then.

The engine loom and ECU run standalone through the ignition switch, but all the interior things are usually switched by a relay. That relay usually disengages when the starter is engaged (your radio goes off etc). You have the opposite problem.

Is this a standard car? Or have you changed the locks or interior loom as part of a conversion? There are around 4 types of ignition switch wiring where the colours changed, but the plugs still fit each other. That could give you the possibility of reversing relay functions etc.
