First check the motors in both lamps are working. Switch on the lights and they should do a up down self test.

Never heard of the thumb wheel to become faulty before, if it has start by changing the front of the LSM.

Even try a battery disconnect, you never know.

Right first off,Neither of the lights do a self test.So whats next? How do I check the motors on the head lamps

Another possibility, check the loom that runs over the chssis leg. Could have chaffed.

It's unusual that both motors have failed.

I hate electrical faults

I know this gets said a lot but always default to the good old battery reset as a first move on such niggles...

Well I did a battery reset,The N/S one is now working but the O/S is not so I think its a bumper off job to check the wiring and/or the stepper motor for operation or the wiring on the chassis leg.

Is there a how to to check the stepper motor??

I've never seen any info on checking the headlamp motor. On that basis alone, I'd be very surprised if the motor itself is faulty. I know the mechanical linkage from it can give issues due to seizure, but it's very rare. I'd put my money on a simple electrical fault. But simple doesn't mean easy to find. The chassis chafe is favorite.
