2004 CHEVROLET TRAILBLAZER EXT Visibility Problems

I HAVE A 2004 CHEVROLET TRAILBLAZER AND THE REAR GLASS HAS SHATTERED 2 TIMES THE FIRST TIME WE REPORTED IT AS A WINDOW BEING SHOT OUT BUT IM NOT SURE THAT'S WHAT HAPPENED NOW THERE WAS NO PROOF THAT'S WHAT HAPPENED FOR SURE I OPENED THE OUTSIDE DOOR TO MY HOUSE THEN I SHUT IT TO HEAR MY WINDOW SHATTER INS PAID TO REPLACE IT AND THAT WAS JUST OVER A YEAR AGO IT COST A TOTAL OF 1200.00 TO GET FIXED THEN LAST NIGHT WE WERE GETTING STUFF OUT OF THE BACK OF THE CAR AND AS MY HUSBAND PUSHED IT SHUT THE WINDOW SHATTERED INTO A MILLION PIECES THIS WOULD HAVE CUT HIM UP BAD IF IT WOULD NOT HAVE BEEN COLD AND HE WASN'T WEARING HIS WINTER COAT WHAT IF IT WAS MY 8 YEAR OLD GOING OUT TO GET SOMETHING . NOT SURE HOW WE ARE...

WE ARE THE OWNER OF A 2004 CHEVY TRAILBLAZER. I WOULD LIKE TO FILE 4 MAJOR CONCERNS REGARDING OUR VEHICLE. THE FIRST I HAVE BROUGHT TO THE ATTENTION OF THE CHEVY COMPANY. OUR TRAILBLAZER WAS SHUTTING OFF DUE TO A BAD SEAL SOMEHOW CONNECTED WHEN THE HEAT/AIR IS RUNNING. THE VEHICLE JUST SHUTS OFF AND YOU LOSE COMPLETE CONTROL. WE HAD AN OUTSIDE MECHANIC FIX THE PROBLEM. THE SECOND IS THE LOSS OF OUR WINDSHIELD FRONT WINDSHIELD WIPERS. THEY NO LONGER WORK. THE 3RD IS THE REAR MOLDING BROKE LOOSE FROM WATER COLLECTING AND THEN FREEZING WITH NO WAY OF PREVENTING THIS FROM HAPPENING. WE LOST THIS PIECE OF MOLDING WHILE DRIVING ON THE HIGHWAY AND IT HIT A SEMI TRUCK. THE 4TH IS A MAJOR ELECTRICAL PROBLEM THAT HAS NOT BE ABLE TO BE DIAGNOSED. EACH MORNING WHEN STARTING THE VEHICLE, THE SUV WILL ACT LIKE THE BATTERY IS...

MY AIR/HEAT ON OCCASION HAS NOT WORKED. THIS HAPPENED A FEW TIMES WHERE I WOULD TURN ON THE SYSTEM AND EVERYTHING WOULD SOUND LIKE IT WAS ON BUT NOTHING WOULD BLOW OUT AT ALL. MY VEHICLE IS OF COURSE OUT OF WARRANTY AND I WENT TO MY MECHANIC WHO SAID THIS IS AN ON GOING ISSUE WITH MANY GM VEHICLES. CURRENTLY MY UNIT IS NOT WORKING AGAIN. *TR
