you hit the nail on the head. took it to a chevy dealer, Dimmitt chevrolet, in clearwater, fl. who on another post was supposed to provide great service but the service tech, Larry wasnt there , they could not make a decision on the warranty coverage without larry,

(hope nothing happens to him) so i took it to autoway chevrolet and they found just what umpire13 said and the part is on order. should be here in a week or less. thanks again umpire13.
