I have a 2005 5.4L F150 supercrew. At different speeds i get a high pitch whine or squeel from the dash, could it be the speedo cable??? It does it a 60km 85km 115km,real annoying and don't need another repair bill, please help thanks.

 

What truck? what year? They pretty much quit using the cable in 99 or so. I know my 99 dont have one. Could be some garbage got down the defroster..
