Mid range whining/harmonic noise
I know it's impossible to describe a noise coming from a truck- looking to see if anyone has some insight. I have a noise at idle only- started during cold starts and now just when idling and in gear. It sounds like a pulley bearing or something. Not sure if this has anything to do with it but I was sitting in parking lot the other day and turned a/c on- after a few moments I thought my truck was on fire. Looked like smoke from under my hood. I jumped out and smelt freon. I shut her down, turned off air and restarted. All was good - I ran air again- no issues and still blowing cold. I'm boggled and annoyed at this new noise! I have a video but don't know how to attach it!

thanks for your reply that's exactly what my truck is doing and while it's annoying my main concern was "what's going on"...kind of sounded like the belt or possibly a bad bearing so when I read this post I had to chime in
