Has anyone had one of the set/resume switches (right grip) go bad on them? I think I have it narrowed down to this as my problem. Any other ideas?

 

Would be the first thing to check anyway with TBW

 

I have an 08 Ultra and had to have it replaced last summer under warrenty.
With the cruise switched on the speed would only set after repeatedly hitting rocker switch to set. All would seem fine then the bike either would speed up on its own or the cruise would just shut itself off. Unuseable the waqy it was acting. We were on a trip down to Virginia and we were heading back to Ontario when this started to happen.
We went to a Harley dealer down there and they confirmed the switch but were unwilling to repair it so I had to ride back without the cruise control. Dealer back in Canada fixed it the following week for me.

 

I had mine go bad in less than a year. The cruise was an addon. Now out of warranty. I didn't mind paying $200+ for it the first time around but, damn I hate to pay it again for 1 failed switch.

Cruise disengages on it's own.
If accelerating with switch it will keep on going after you let go.

 

First thing to check is to see if your brake lights are working.

 

When mine acts up it will throw a code. Once back to normal the check engine light will go out.

I don't remember all the right steps. But the electrical manual will explain how to look for past codes...

That or someone will chime in with the exact steps.

 

I'm sure lubing the CC cable gets overlooked.

 

Had to replace my control switch (right side) this summer. 1000 miles into 4500 mile trip (Sturgis) it quit. My son liked the fact I had to 'twist' for the rest of the ride (he was on a Street Bob)! It was still under warranty and I'm given to understand this has been fairly common. Mine's an '08.

 

Had mine go out twice. Both times the check engine light would come on and the cruise would not activate. It was a micro switch in the housing. The bike is also an 08 Ultra

 

Mine went out on my 04 Ultra while on a trip. Dealer in York,PA worked on but could not fix and I could not wait for new part. They graciously offered to let us wash our bikes and furnished everything, including a power dryer. After drying the bike, including hand controls, the cruise worked fine. Could you possibly have some water in the contol housing from rain or washing?
