headlight wipers

Welcome to the site mate 
They do tend to fail with time, the dealers charge Ԛ£88 for each of the motors, so you would have three options:
- Pay the stealers for new motors.
- Get them cheaper from somewhere else
- Or just remove them and never fit ones again.

The headlamp wipers probably don't require any new parts, just a bit of servicing
Remove the wiper arms,( 8mm nut each), remove the headlamp grilles,(three clips and two self tappers), remove the headlamps, (three large self tappers each + several plugs), and remove the wiper motors,(two six mm nuts and bolts each).
Unclip the motor rear covers and how the mechanism dismantles should be obvious, except you will probably find that the long output shafts are seized up.
Work on them untill they come out, clean everything up, grease it all and reassemble.
Before refitting them test them by applying 12V to them.
Brown is negative, red or black is positive. If 12V+is applied to the red , they will run continuously. If applied to the black, they will complete their sequence, then park.
The motor with the extra wire in the plug controls the headlamp washers, so if this wiper doesn't work, then the washers won't either.
You may have to experiment a bit to get the wiper arms on the right spline. Don't forget the wipers only operate every fifth time or so that you use the windscreen washers with the lights on.
