Instrument Cluster not Working Properly ! (Tacho & Rev)

So i have this problem when i got the car, Its been through a crash before i got it

The Issue with it is that the Rev and Tacho doesn't work sometimes, for example ill be driving and the speedo and rev would be fine and then it would just both drop to 0 and the Kilometers on my dash would just disappear ! only thing that would be working is my Fuel gauge and my oil gauge !  

so i wouldnt know what speed im going or how high my rev is, and then it would just come back to life after driving for a while. Sometimes i start the car and it wouldn't even work.

So most of the time i have to have my GPS Speedo reader on my phone so i can keep track of my speed.

The fuse is fine, i hear people telling me to replace the Instrument Cluster but im worried it would do the same thing because it is working and for some stupid reason instead of my REV being at 1000RPM when its warm and stationary its always at 2000RPM, some faulty shit going on but the engine is running perfectly fine.

People said the Speed sensor might be faulty at the Ground cable, but what do people think it is PLEASE HELP !!

Read my post in the other thread. And for future reference a fuse will either be blown or not, so if it was a fuse the issue would stay.

Read my other post. I cant be bothered typing it again lol

Hey thanks 89cal but you have so much post and reply I can't seem to find the topic on your profile LOL

Take it out remove & clean the 3 electrical connectors replace them & check probably a bad connection by the sounds of it. Be gentle as they are just strip connectors just clamped in by the plugs.

So now it got worst and now my REV Is OVER 9000 !!!! And got stuck there

Now should I just replace the whole cluster ?

Before replacing the cluster have you PM'd the guys above or followed what has been suggested since they're familiar with your cluster's issue?

Have you used an electrical connector spray to dissolve oxidation? Being an intermittent problem it cannot be the fuse anyway. Have you tried this cluster on the same model of a mate?

[89CAL]

What did you do to make it do the above?

Cluster needs to come out to have a look what is going on at minimum. May even just be a shorted wire etc

Dry solder might need resoldering perhaps ?

[breaker1845]

Easy way to explain it is dry solder/contacts in the PCB of the cluster, specifically the speedo. The soldering of the clusters is usually of poor quality and overtime it's easy for it to go 'dry' and the condition degrade, causing intermittent faults on the cluster. If you aren't the best with a soldering iron/electronics you can get a place to do it for you and test it for like $200 or something and restore it to new condition I guess. To sum up, the electrical circuit on the PCB which gives you the reading for your tacho has a bad connection due to dry solder/contact but the needle still works fine resulting in the obscure rpm's you see in the cluster.

I tried everything and I gave up, I bought a second hand cluster and it works AND FIXED ALL THE PROBLEMS !!!
