Buzzing when I start and turn off

[chrisschweder]

First post here but have been lurking since last Spring.

I noticed when I start my truck and turn it off that I get a buzzing noise which sounds like it is coming from behind the gauge cluster. It is only for a second or two. Sometimes a little longer. I did a search and the only thing I could find was the MFS but that buzzing was with the blinker activated. My switch has been working fine. Any ideas?

did you check all the functions?

is is possible that copper in the grease could be arcing while the switch is idle

my bet is if you cleaned it out you'd fix the buzzing
