Hi all, i would like to thank this site for info on fixing my instruments. The problem was my Ve Commodore 07 ex police car, instruments were dead no gauges were working and the steering wheel controls not working. I pulled out the cluster and released the clamp on the back as shown in this site. I put the fitting back on (nothing still) then I pushed the fitting in and out and bingo everything worked, except the next day they went out again. I bought some CRC automotive electronic contact cleaner from super cheap $22 and sprayed the pins (socket and plug) and tried to clean them with small paint bush. The cluster is still working after a week so may be ok. I noted that thereare about 17 pins, 3 pins for power, there is a 12volt pin and ignition pin 12v and an earth pin, due to nothing working when ignition was on or off I think it was the earth pin open circuit. Anyway I would have been f---d if not for the info from this site, had it booked in at holden probably charge me for a new cluster.
thanks again Grant
