Click wheel is haunted
I must have some dust or something in my click wheel. The volume starts going up and down on its own while playing a song and if I try to use the wheel, it's very jumpy. It's pretty bad if I leave the iPod in my car and it gets hot. Once it cools off, it works normally for the most part.
Can I clean underneath the wheel without taking it all apart or do I just need to replace the click wheel altogether?
Well, if you want to give cleaning a try I'm almost certain you'll have to take it apart. But I agree that chances are that it's unlikely to be dust.
From your description, however, I get the idea that it's the click wheel that has been damaged, and it can be replaced.
They've got one here:
Don't know if you'll be able to find one without getting a new front cover with it. And worst case senario is that it's the logic board that's damaged.
