Here are 2 sources that may be useful.
If you dismantle the arm mechanism ,check the spring attached to the arm, sometimes it comes off.
Clean the piston that moves in the solenoid and all fulcrums with brake fluid cleaner.
I also found that the insulation on the copper wire for the bulb was shorting out. Is affected the movement.The insulation inside the arm frame had disintegrated . I unsoldered the wire, removed the copper wire for the bulb holder, cleaned it refitted with heat shrink where it goes in the frame and put it back together and re-solder it.
I can send some photos via email if you need them?
Good luck.
