speedo stopped working advice

[scotzman]

Hi All.,.

  Speedo on dash and digital not working .. On getting it checked out it was suggested the console behind heaters is at fault..

  Anyone any suggestions on recommended fixes  for this..

  Thanks

Possibly the box, do you know a local owner that would swap over to try? Its a 5 min job.

 

is it an import?

Is it just the speedo(s) or the whole cluster? I'd start with fuses personally but I believe the fuse that does those also does the whole dash so you'd know if that was broken!

Garage suggests white box behind heater.. dont know another 350z owner to try a swap. Also would just a different box work or would i need additonal components. Yes an Import.

thanks..

This one? Pretty sure that's just the climate control ECU is it not?

Cant imagine the white box would cost much and would be the first port of call, unless its an import and has a speed chip somewhere.

 

It is all linked through that box Longshot.

Ah, got it.

[scotzman]

Yes an import unknown if it has the chip..

[Jetpilot]

Ok, then if it shows miles per hour, it most likely its been chipped somewhere, usually behind the speedo, i would pull the cluster (easy job) and see whats behind first.

[scotzman]

Hi jet.. yes its showing mph what would i be looking for ?

[Jetpilot]

It should be pretty self evident if the wiring looks like its been spliced, you are looked for something like linked below if you click on the speedo converters:

It might also just have the dial replaced, but then the trip would still be reading in kmh for the distance?
