1989 325iS Gauge Cluster Problem - BMW Forum

Calypso22 · 06-28-2008, 01:29 PM

I am experiancing problems with the right side of my gauge cluster. My Gas level and Speedo work fine, but my Tachometer, fuel economy gauge, and my temp gauge are all not working. I looked at the fuse box just to see if anything was blown but all my fuses are working. So I am curious on why it is that it would only be one side.

you have something like 3 wire sockets that connect behind you instrument cluster. Perhaps, 1 of them popped out.

Yea I took a look where the cluster is and im not seeing it there are these two wires that are connected to each side other than that noting was loose.

I had a similar problem, and a closer look proved that it was a fuse after all.

I looked at my fuses and they look fine. Which fuse is it? If you know or not

i'm scratching my head on this one... there are at least 20 wires connected to the instrument cluster; divided into 2-3 wire socket connectors...

you'll realize diagnostics by description relies solely on how well you can describe what you see, feel , and do... thus, your description of "two wires connected to each side... just doesn't make sense...."

you wanna try again and be more descriptive???

So I have to take out the cluster?

If your talking about replacing the batteries on the SI board then yes you have to pull the cluster...and take the cluster apart...and then solder new batteries onto the SI board.

I chickened out and just bought a new SI board...I'm not sure if that's your problem or not though.
