Default Volvo 940 1992 speedometer now working properly

Hi guys, just bought myself a volvo 940 1992 b230ft with a m90 gearbox.
However i got a problem with the car; the speedometer is not working properly. The RPM's is working, and the KM/H (speed it self) is not. Any suggestions on how to go forward on this? and how to check if it is the speedometer or the power or sensor into the speedometer.
Thanks in advance

The speedometer's capacitors are more likely the problem, need to be changed--not a simple task. You may check the differential pick up wiring but chance are it's the speedo. 1992's are pretty commonly bad...

https://www.volvoclub.org.uk/faq/Ele...eterRepair.htm specific for 1991-1992 740/940 speedos.

you can't replace these instrument panels with a different year, as the gas gauge will be way off if you do.
