my bmw has headlight wipers any idea how to make them work and if they dont work what could be the problem with them

Thanxs

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.

cheers mate any idea how they work

when operated the n/s one is wired to the switch and the o/s one is driven by a conection to the left......does the water still souirt on them or does nothing happen at all

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.
