This is very hard to open, maybe invest in special tool.
It is likely that a cog wheel has come off an not a scredew up wiper motor.
It is also quite likely that a cog has worn itself out, in which case you need to replace the cog.
The wiper motor is extremely expensive... even used, so I hope there is some noise coming from this box when you try to use your wiper or your wiper is likely banjaxed...
