I have an interesting issue. Occasionally my speedo dies out, it will read the speed and then drop instantly down to 0 and then run up to speed quickly. Then, more recently the speedo has cut out altogether. When it goes I lose the display and the idiot lights and also the indicators. It's blowing a fuse which should have nothing to do with any of these things and the indicators and display should be on seperate circuits. She was pretty filthy but cleaning out the speedo pickup hasn't helped. I've also cut and removed a damaged rear indicator which I thought might be shorting, none of this has worked. I'm slightly concerned that the dash itself is going which won't be cheap, I'm sure... Anyone got any ideas???
