When something like that happens in a good ole g-body the first suspect is the fusable links going to the starter...might but wrong,but.......

Is their any power at the fuse?

It has contacts that are over 20 years old. Try taking the cluster out and cleaning the brass contacts in the white connectors in the dash. I also like to bend them outwards SLIGHTLY to give them better contact. The cluster may also be loose on the black plastic piece it screws to ( over time, they loosen up). Since the plugs do not have a positive engagement to the cluster, any looseness will cause a bad contact.

If you're going to pull the cluster out here's a link that will help:

I did the same thing last spring on the '86, my gauges were just reading off slightly. As 85 Brougham stated, clean the contacts at the dash connector and also the circuit traces on the back of the cluster, as well as the contacts on the bulb holder. I used a pencil eraser - worked great. I took apart the cluster and cleaned everything too. I would suggest while the cluster is out to replace the bulbs as well; they're #194, #168 & #161s (about $1.50/pack of 2). Lastly I sprayed lubricate on / in the speedo cable at the dash end.

Know it sounds like a lot but since you have the dash opened might as well take care of those things.

Homer Glen, your not too far from me.

Glad you got your gauges working. Those "fingers" on the flexible printed circuit get dirty, the plastic drys out and the copper foil will seperate (i.e lift)
I am converting several of these units to White Dial Faces with LEDs and el
dial lighting. Once everything is cleaned and working (a soft eraser works best) I personally Armor All the flexible PC circuit to keep it from drying out (those under dash temps get really high!) Then clean contactrs again with "Q" tips and alcohol.
If the bulbs are good (you can check with a Volt/ohm meter. Your Inst. lights are connected to you headlight dimmer. Make sure it is turned up and see is the lights for you Vent. Control Light and work with dimmer.
