Anyone know of any known issues with the ribbon block on the interior light or an issue with dim or unlit buttons...

I've had an issue with my buttons not illuminating, or having any power whatsoever (so not turning light on etc) since fitting my rear light and footwell lights way back, so i assumed i'd slit the ribbon in the roof lining etc but something weird happened today...

I Got in the car after work and the buttons where lit, as i drove they dulled and lit etc, buttons would put the light on also and the only thing that's different is I dropped the roof lining to check all the length of the ribbons (all perfect) and fit a new aerial base this weekend, so...

Would a dodgey earth effect the buttons, or are the blocks weak if removed regularly and heavy handedly... Anyone had anything similar, how did you solve it?
