instrument cluster malfunction
My 03 CTS cluster stopped working on me last night. It is stuck at 2,000rpm, 35mph, and a quarter tank of gas. Also it doesn't light up anymore. The only thing that lights up is left, right, and hazard turn signals. Also the red gear selector light isn't on. I tried the easy route and disconnected the battery and checked my fuses and nothing happened. Anyone have any idea whats going on.
First thing I would try is disassembling around the cluster to remove it and check for any connectors popping off then work back from there, you might find a loose connection and then when you put it back in place it works again, depends how its plugged in at the back.
Check the fuses under the hood one is labeled ELEC PRNDL, also worth checking any other fuses in that block.
Have you checked fuses also in both rear under seat blocks both left and right?, if not check them all one at a time.
And there are more in the fuse boxes under the rear seat.
I've read this a couple times but kept on having the brain fart of the century. I have seen this problem before, so I thought, but I couldn't figure out what the fix was.
With the previous problems with the IC, for some it was the connection on the back. While for other's it was the IC itself, or either they couldn't figure it the connection out. Some who could, said there was a cold-solder joint on the board for the IC, hence the connection. So if you are able to solder, then I suggest removing the IC and re-solder the solder joints.
