In the instrument cluster the only needle that registers is the gas. The Speedometer, tach, nor temp registers. The trip gauge doesn't work, the mileage does't increase. I've done the diagonstic test, it goes through the motions but the results are the same. Do I Need A New Cluster or Is there some sensor I should be concerned with?

have you got a dimmer switch on your model to dim the dash lights. if you have it may be faulty. link the cables together if the lights work the switch is faulty. if you have not got a dimmer switch
your printed circuit on the back of the dash may be faulty or the plug in the back of the dash is not pushed all the way in. hope this helps

It may not be a bulb, as the instrument cluster usually has a number of bulbs and they probably didn't all blow at once. Pulling instrument clusters can be touchy and may not be for the average "shadetree mechanic" however, typically there are a few screws above the cluster going into the dash pad and a few hidden behind the trim panels below the cluster.
