I’m going to guess its cable driven, my red top was. If so then it’s probably that the cable is fouled somehow e.g. twisted or the connection to the speedo clock not on correctly.

several times i push it up or down and it works for a day or two then stops, otherwise i changed the previous dash with a white one, the other clocks are ok

Sounds like it’s either not connected properly or the cable is damaged/broken. You’d need to take the clocks out again and have a look at both the connection and the cable end

Yes I agree. With agw 9262

Both ends of the cable must be pushed firmly home ........especially where the cable plugs into the back of the clocks.....When you push the cable in you should hear a positive click which comes from the spring metal tab on the back of the speedo which retains the cable in position.

The cable inside the outer housing is metal but the worm drive inside the speedo gauge is mainly plastic which due to age and the plastic is prone to fail. ...A new cable is relatively cheep and fairly easy to replace.....however
before you go out and buy a new cable......make sure the connection points on the gear box and into the back of the speedo are sound.
