Becker Grand Prix TG schematic request and seek function not working

[col320ce]

Has anyone got a schematic for the above?

Also, the auto seek is not working properly; it is motor driven working in both directions. 
Motor works intermittently
Need to press and hold the name plate down to make the dial move (rather than moving by itself after the initial press)

Does anyone have some insight into this part of the radio?

Thanks Mark!

Anyone have any thoughts on fixing the auto seek??
