2006 GMC ENVOY XL Visibility Problems

WHILE DRIVING I TURNED ON MY LEFT BLINKER TO TURN. THE WIPER CAME ON AND IT SPRAYED WINDSHIELD WASHER FLUID. I PUT IT BACK INTO THE NEUTRAL POSITION AND THEY KEPT SPRAYING AND WOULD NOT STOP. I PULLED OVER TURNED THE VEHICLE OFF AND BACK ON. THE WIPERS CAME BACK ON IMMEDIATELY AND CONTINUED TO SPRAY WIND WASHER FLUID. THEN MY SPEAKERS STARTED TO PLAY A DISTORTED SOUND. I TURNED OFF VEHICLE AGAIN ABOUT 4 MORE TIMES AND EVERY TIME THE WIPER BLADES AND SPRAY CAME BACK ON. I HAD TO STAY PARKED ON THE SIDE OF THE ROAD FOR ABOUT 10 MINUTES THEN THEY STOPPED. OR SO I THOUGHT, AS I STARTED TO DRIVE AND HIT 20MPH THE WIPER BLADES CAME ON AND IT STARTED SPRAYING AGAIN TILL IT FINISHED THE ENTIRE GALLON OF WIND WASHER FLUID.

I OWN A 2006 GMC ENVOY AND MY DAUGHTER HAD GONE OUT TO GET SOMETHING OUT OF THE BACK. SHE CLOSED THE HATCH AND WAS STANDING THERE TALKING TO MY BROTHER-IN-LAW AND THE NEXT THING YOU KNOW, THE WHOLE BACK EXPLODED OUT! IT WAS HORRIFYING. IT SOUNDED LIKE A BOMB GOING OFF! MY DAUGHTER WAS SHATTERED WITH GLASS BUT FORTUNATELY WAS NOT INJURED. *TR

BACK WINDOW ON MY 2006 GMC ENVOY EXPLODED WHEN THE TAILGATE WAS CLOSED. GLASS WAS NOT PREVIOUSLY DAMAGED IN ANY WAY. HINGES HAD JUST THE DAY BEFORE BEGUN MAKING A NOISE WHEN TAILGATE WAS OPENED AND CLOSED. MY HUSBAND'S HAND WAS CUT. GLASS FLEW 20 FT. OUT OF GARAGE WHERE CAR WAS PARKED. NOISE OF EXPLOSION WAS LIKE A LIGHTENING STRIKE OR GUNSHOT. *TR
