Today, for the first time, when I turn on the heater the fan sounds like you stuck in a piece of paper in there and the fan is just going - Rrrrrrrrrr humming sound. The heater works - as it seems but this weird noise now exist. Any ideas. Also the sounds seems to come more on the passenger side. Any idea of what it may be and cost to fix
FYI, I bought a 2007 Tahoe (nice setup) but I still love this car!
