o.k. guys need a little help.I have a 2010 SHO with 17,500 miles on it ,has been a great car.A couple of days ago when i left home and turned on the outside air thru the vents there was a series of clicks (6 or 7 ) before the fan kicked on . Everything was normal after that.Sounds like a gear slipping trying to adjust the flow of air into the cabin??
