On Board Computer Different Problem

I've had no on board computer for a while now and didn't really give it a second thought until I realised I can't change my clock

I got a spare indicator stalk and pulled it open and checked the cables from the bc button were intact and the switch is working then put it in the car. The OBC still isn't working so I checked all the fuses and they are all good and still no OBC

I was tempted to get a spare instrument cluster and try it but as far as I know that will leave me with a tamper light on both, next up i'll check for a break in the wiring from the indicator stalk to the cluster so i'm looking for a wiring diagram if anyone has one?

MIGHT be a chance (highly doubt it though) that something in your car reset and it disabled your OBC function which might need to be re-activated by PA Soft or similar diagnostic program.

Did your car come with the stalk that says BC on it in the first place?
