Mine does it when the accessory power is on. Don't know what it is, but I try not to leave it on for extended periods.

Okay thanks guys..

So far it's a tie, one truck does it and the other doesn't.

Anyone else's truck buzz when in auxiliary or accessory mode from the passenger side front wheel well area?

If it is normal I'm curious to what it is.

I just went out in the rain and checked for you...everything turned off and ignition in "on" position...I can hear the buzzing. No idea what it is and did not try to trace it. If you find out, let us know.
