I misspoke a bit in the original post. on the top of the unit, two cables attach to the flat, elliptical shaped plastic piece, not all three. The cables are held with cap nuts into grooves in the black plastic piece, and move in the groves when the selector lever is moved from Off to Normal or De Ice. The third cable attaches to the bottom of the unit. Mine is good there. My whole unit would be fine if that little plastic piece wasn't missing a piece, but it's pretty useless without it.
