I've had this rattle (buzzing) sound behind the glove box since purchase. When it occurs you can take your foot and press up against the wiring and it will stop. It only occurs on cold mornings while the truck is warming up and driving below 20mph. Anyhow, I thought it was the plastic coating and placed zip ties around it tight. Seemed to help for a couple of weeks. Now its back. With the glove box removed and the buzz occurring I can still put my finger on the wires and it will stop. A lot of vibration can be felt here and in the floor board.
Anyhow, I haven't taken it to Toyota because unless you drive it first thing it wont do it. And, once it warms up it does not do it. Unfortunately my drive to work is short and slow and it buzzes all the way in. In the afternoon, there is no buzz.
I guess its something that once warmed up (expands) and then fits correctly so it doesn't rattle. There are a lot of plugs and a ton of wires behind the glove box and I can't rule out the exact place its coming from.
Has anyone else had an issue with this behind the glove box?
