first, disconnect the negative terminal on the battery, you will have to pull of the front of the dash first, then you will see four bolts on the cluster, one in each corner. remove those and the cluster will slide right out. unplug the harness connected to the top of the cluster. the cluster will then basically pull apart from there.

You have to pull the gauge cluster out. On the back of the gauge cluster there will be little gray bulbs that twist in, turn them to the left and pull them out. Be carefull not to break the clips on the dash while removing it, or installing it.
Bad stepper motor in instrument cluster. Very common problem. Search for "speedometer whizard" in Google.
The fuel gauge is integrated into the gauge cluster. To replace the gauge you need to replace the entire assembly. You will need to remove it-which is very easy, and give the dealer the number from the back. It will take a couple of days to get a new one. I'm in the process of doing one right now.
