Dear jshatzer,

Hope you're well. I deferred commenting, in the hope that a Brickboarder would respond, who had a wiring diagram for a '92 960. I do not have such, as I don't own a 960.

The intermittent symptoms suggest a loose ground wire and/or a corroded ground point, or a circuit card failure.

The ground points for a '93 940 instrument cluster (the closest I have to a '92 960) are: (a) on the inner fender walls, behind each headlight unit (North American models); (b) next to the ECU, which is behind a panel on the door-side of the passenger footwell. Clean these contacts with an aerosol corrosion remover (or very find sandpaper). Apply a thin coating of di-electric grease and reconnect the ground wires.

Do not trust a visual inspection. A corrosion layer may be only a few atoms thick, so invisible to he unaided eye. Clean the contacts, coat with di-electric grease, and reconnect the ground wires.

If this ground point clean-up does not help, it will be necessary to pull the cluster and closely inspect the circuit card.

Please post back with any results from cleaning the ground points.

Hope this helps.

Yours faithfully,

Spook
