Need a bit of help and advice.. so here goes..

Had a corsa c in part ex a few days ago the speedo cluster is playing up. Some of the warning lights dont light up on ignition and the mileage display is so dim you can barely read it. Also when you indicate left it doesnt light up on the dash but right works. Someone at some point changed the LEDs to blue so took the clocks out and put standard bulbs back in and still the same problem. Ive briefly tried another set of clocks where on that all the lights light up apart from again the mileage display is dim. Any idea as to what the fault could be? Also if I was to get another set of clocks then what would I need to get them programmed in and mileage adjusted? Is it just a case of visiting [MENTION=4]Pecky[/MENTION] to get them programmed and mileage adjusted? If I do get a set of clocks it wont have no codes or anything as it would be out the scrappy.

Thanks
