Today I had my key in the ignition, and I turned it to "on" to activate radio, air blah blah.

It was pretty quiet in the truck, and I heard a strange noise coming from behind the dash, near the middle. The noise originated slightly to the right of my radio.

It almost sounds like a faint sizzle, like someone is frying bacon in another room. The intensity of the sound fluctuated slightly, but mostly kept the same level of volume.

What could this be?

 

Anybody have any idea? A buddy at work said that it may be a relay behind the dash. I dont know so im not sure.

 

Are all the fuses going to the dash good (ie radio, etc.)? Just a thought, but I may be of no help too though lol.

 

I have the same thing going on. Anybody? It almost sounds like a leaf or somethingin the blower. At least for mine anyway.

 

^Well, the noise left, but it wasnt anything in the blower. It sounded electrical. I havnt had a chance to listen for it again.
