Cectra C. dials not working after removing them?

Did a led conversion on Vectra c everything ok, but when I did the clocks and replaced them the dials didn't work apart from the rev counter. All other warning lights work and also the back lighting just not the dials.
Tried resetting them but nothing, does anyone have any ideas ??

#fixed# It turns out I was too rough when removing the clock needles and pulled the stepper motor gears out of place, quick fix just pulled the back off the stepper motor, aligned the gears then put back together

leds can only go in one way but they are all working. Temp is now working its just the speedo and fuel gauges not working. Maybe blown the stepper motors ??

Are the LEDs you used polarity sensitive? Can they be put n back-to-front?
