The warning cluster is known for bad cold solder joint problems. Typically,
having a non-functioning (digital) clock is a sign that the unit needs to be
resoldered. Also, verify that all the lights are working by doing an initial
"key on" - this should light ALL lamps within the warning cluster.
To remove the warning cluster, pry the bezel off by prying the front corners.
There are two clips that hold down the bezel to he dash. After removing the
bezel, you should be able to access the two Phillips screws on each side of the
warning cluster. Removing the two screws should loosen the warning cluster
itself. You'll need to unplug the main wiring harness from the rear to remove
the warning cluster totally. Once removed, remove the three screws from the
rear. You'll need to remove the small flathead screw that secures the adjustment
knob in place, as you'll need to remove the circuit board from the main housing.
Once the circuit board is removed, concentrate on resoldering the main cold solder joints
that connect into the main wiring plug. This will fix the intermittent problems
99% of the time.
