Weird noise when foglights turn on

[DenaliAJ]

Anyone with a Yukon or Tahoe noticed a weird noise from the rear when you turn on your foglights?  When I turn mine on it sounds like a solenoid is popping in the rear or something, I dont know what it is...just want to make sure its normal and Im curious as to what in the rear is related to the foglights?

It could be your rear wiper moving a little when your turn the fogs on.  Someone had mentioned that problem the other day.  I'll see if I can find the thread and post the link in here for you.

On another board they talked about this, this has been a problem with the grounding.  I am taking mine to the dealer later this month to repair.
