Blower switch issue

[Canuck2500hd]

This morning my truck's blower went crazy, all i get on high position is a click from the selenoid, no action from the blower. The truck is a 06 2500hd 6.0 with manual heat/temp. Any Ideas?

Are *all* the speeds busted or just the max speed? Do you turn your blower off for long periods of time while driving?

Just #5, I usually have it on at least 2 or 3 at least during winter.

Here's something to chew on. Not sure if this will help. Might want to read the whole thread, it's not too long. It's an older truck but it could be similar.

Thanks alot for the info. Truck is still under warranty tho, so i'll probably send it in if I can't find the issue.
