The Datsun 1200 windshield/windscreen wiper motor is very reliable. A 38-year-old unit was disassembled and no problems found. If the motor is still working, just lube the linkage, this will make it work well. However, if you wish to repair a broken one, here is how you can dissamble and inspect it.

Overview

These are the only tools you'll need: Flat and philips screwdrivers, 8mm and 10mm wrenches:

Removal

In the engine compartment, pull the connector apart. There is no catch or locking tab, just wiggle it straight apart.

Go into the cabin, on the passenger side, and look under the glove box for this cover:

Remove these four screws on the firewall:

This will expose the motor shaft and passenger-side linkage

Pop the clip off the linkage with a flat screwdriver

This is where to lubricate the linkage:

The ball-end needs lubrication inside and out. Roll grease in as you would do a wheel bearing.

Now that it is disconnected from the inside linkage...
Remove the three 10mm screws holding it to the firewall.
Then pull/pop/wiggle it loose, as the rubber tends to stick after 30 years...

Tilt the motor so the shaft linkage clears, and remove from the firewall
