Thanks for the suggestions fellas.
Upon further inspection, I have found NO leaks or dragging belts, pulleys, pads etc.
I DID notice that the middle 3(?) fan speeds all blow at the same rate.
Only the low & high settings differ.
I suppose my blower resistor and/or switch may indeed be on its way out and I'm just smelling its slow, painful death....
Does anyone know FOR CERTAIN if there is a time limit on the related campaigns/recalls/TSBs? ...or will I just have to shell out the 20 bucks & buy the part for a DIY?
