Hand and thumb wormer problem ??

[snobill]

On my 12 apex xtx ,So they both turn down but don’t turn up I was thinking it was the switch’s but both at the same time? And after my hands got cold I turned my handle bars back and forth a few times while trying to turn both up and it worked ??? A short somewhere ? What do the apex experts think?

Dirty contacts in the switch.

Both at same time ? hopefully it’s easy to take apart
