Half of the lights in my instrasument cluster is off

[newsh]

I think there’s a circuit board track inside the gauge cluster that can burn out leaving half the cluster dark. I’m sure someone had this problem on here.

I found this old thread and was told the lighting booster could be the problem:

However looking at wirering diagrams at s2central.com I cant really see that the booster could cause this?

Ahhh yeah Oki.

I managed to find a the wiring diagrams for the instrument cluster. So will try and put some power on and see what is what.

Some confusion between instrument cluster and lighting cluster [emoji6]

If you have an avant check the wiring harness in the lift gate. Wires break and chafe due to frequent opening and closing.

Are you saying that this could be related to the lift gate? I will check it.

Ok so not the plug but the connector on the dash. Problem is that I tried with another instrument cluster and it had the same fault. So I dont think that two instrument clusters will have the exact same error.

I dont remember exactly color, but i advise you to check both or all connectors for poor joints

[Jonas_R]

Yes what?

[valjo]

By dash connector do you mean the blue og yellow plug or the connector soldered to the PCB?

yes

[Jonas_R]

Have you tried adding temp ground or power to see if either fix it and then check back?

No because I'm not sure what pin is ground and what is +12V at the blue connector.

i had same problems. i find out that i have cold joint in dash conector ....
