Rear Window Wiper Washer Motor problems of the 1997 GMC Yukon

Brakes failed at low speed and hit the car in front of me at stop light. Pushed brakes to the floor and seemed to pick up speed. Air bag did not deploy. Totaled the other car. Went right up on top of his back end. It cost me 200. 00 to fix my Yukon. Had already replace abs system about 8 years ago. The back windsheild shattered one day when I got into the drivers seat. The windsheild wipers had serious problem. Replaced the computer part twice.
