Need some help/info about headlight adjust switch

[R Livingston]

Folks I'm not sure what I need to do. When I move my headlight adjustment switch located on the left hand panel below the left hand pocket no movement occurs in the headlight. I can feel a little vibration in the left hand motor at one position but feel nothing in the right hand motor. I was wondering if there was a connection between the two that might be unplugged or are they wired together in the harness. Really didn't want to start pulling the fairing apart if I didn't need to. Thanks for all replies.

Each headlamp assembly has 3 electrical plugs. 1 for its low-beam bulb. 1 for its high-beam bulb. And 1 for its motor that makes each inner-assembly move up and down. The motor plug is located at the bottom, rear, outboard corner at each head-lamp assembly.

The plug is grey and has its connector-release-point on top.

For access to a motor plug, you will need to remove the inner-cowl side panel #15/16 on the fishe below. To do that, remove the lower center cowl #12, the upper center cowl #14, and remove the 2 screws on the underside for #3. Then, pull part #3 gently forward. Now remove #15 or 16.

To test headlamp movement, what I do is start the engine. Then, while moving the switch to the full up position, I look at the headlamps from above and watch the gaps around the reflector edges in the headlamp assemblies widen and narrow as the switch is moved from full up to full down. It sounds like one of yours maybe working.

Thanks Greg. I was wondering if there was a connection between the two motors that might be unplugged since one was trying to work and the other was not.
