The switch (push-in and lock, push-out unlock) works off a little cam lever. Fred’s way works and he shows it in his maintenance DVD set. Great DVD set, much detail.
What you have to do is to remove the switch and disassemble it, being very careful of the spring and those electrical contacts. Fred has used a plastic garbage sack pushed onto the handle bar and acting like a sack to catch your dropped items. I’ve been doing this since my GL1200. I got to learn a lot with old Harleys!
Once you can see the cam lever clean it really good and degrease the entire switch with a tooth brush and a cleaning solution, I use Dawn and alcohol.
Then grease the switch, cam lever, contacts and housing with silicon grease. If you work the switch button you’ll be able to see the cam lever working back and forth. Fred shows this better than I could write it up.
Re-assemble and you’re back in business.
If the lever is broken get a new switch. What is the cost of frustration?
If you don’t like to tinker with this stuff take the bike to the dealer. Warrantee should be good to go if you have the extended stuff. I don’t take my stuff to anyone, not even my buddies. Except the time I had a race shop bore out my jugs on the Harley.
