I just re-installed my gauge cluster and now my tachometer, speedometer& odometer are not working. So I took everything out and cleaned all of the electrical contacts and still nothing.

It has been out of the car for a few months stored in a box. Previously it was working just fine. I did not make any adjustments/alterations to any of the cluster parts.

Are there any fuses that could have popped that is causing this, or is this where I need to send of the cluster for repair / but replacements?

Trying to prepare the car so I can see it, but pretty sure no one wants to buy a car they can't tell how fast they're driving!

 

No one has any suggestions on how to proceed?

 

I'd start with fuses. Is the engine and wiring harness in the car? I believe the ground on top of the engine will keep the cluster from lighting up/working if it's disconnected.

Yes, everything is in the car.
Which fuses to check? I don't see any labeled "cluster'.

 

Check EVERYTHING. There's a lot of circuits that are on a weird fuse that you wouldn't guess.

link for fsm for wiring diagram if you dont have, find and trace all circuits till you find the fault(great fun solving the electrical gremlins on 3rd gen)

 

Just got back into town from a business trip. I checked all the fuses that are near the clutch. Those are the only fuses, correct?

 

Could you might have left a plug off even after checking/cleaning???
Might pay to go back and check again.

 

Nope

 

After a little google searching, I found some other places to check the connections near the computer. (Possible Bad ground)
I found a cut wire (that I do not remember cutting) and a plug not connected to anything.
I have a Apexi PFC, so not sure if these are cut/disconnected on purpose?

 

Lookup a PFC install. There are a few wires that are supposed to be removed and I believe that is one of them. That connecter is for the fan recall. Also normal.
