Ok, cluster came today, pulled it apart, took out lh display and put it in original cluster. by the way getting the needles on in the right place is a bugger, speedo is about 2ks out to the centre digital readout. All working now.
One for the brains trust, I have 3 window cluster and the LH screen goes dark or partial brightness, have tried reseating contacts on the rear, looked at solder joints etc. but no luck.
Any ideas ???
Done the relearn thing, no difference, the LH servos work as well as the upper RH. What does the lower RH one do, Holden spares say they have never sold one
