why do you think the motor still works if the wipers don't move? Can you hear the motor run or can you see a little movement when you turn the switch on?
What happens when you activate the washers?
go to a salvage yard that allows you to remove the parts yourself. Then you can see how the motor and linkage assembly comes out.
don't have 1983 info, but here is 1994:
