buzzing noise
When I turn the hazards back on, the buzz goes away. but when I turn them off, it comes back. pressing the breaks also causing the problem to cease.... Eventually overtime the noise will go away.
ideas?

It sounds to me like your multifunction (signal/wiper) switch might be on its way out. It could have a bad connection inside which is causing the buzz. I think I'd remove the covers from the steering column and see if I could pinpoint where the noise is coming from.
If the noise is coming from further down and towards the center of the truck a bit more it could be your flasher relay.
