Wiper motor conversion

[Dodger]

Hey all,

Worked on the truck all day and all electrics are now spot on. A mate of mine volunteered to fit the new electric wiper motor and after much frustration and swearing, it all looks good, except, it's not moving the wipers.

From what we can see the motor is doing everything it should, moving the arms but not much is happening at the wiper shaft. The shaft doesn't spin.

Are these shafts, that stick out the cowl, prone to seizing up or have we done something wrong. Maybe a trick with these motors that we don't know about??

Any advice would be great.
