2002 CHEVROLET TRAILBLAZER EXT Engine And Engine Coolingcooling System Problems

CHEVY TRAILBLAZER02 MODEL, ABOUT 40K MILES IN 2005 THE CAR DIED ON US 2 TIMES AND WE COULDN'T FIND OUT WHAT WAS THE REASON WE HAD TO ASK FOR JUMP AND IT KEPT GOING ON NORMAL, THEN SUDDENLY AFTER ABOUT A COUPLE MONTH I SAW THAT THE BATTERY WAS LEAKING, AND DAMAGED SOME A/C PIPE LINES UNDER THE BATTERY, HAD TO REPLACE THE BATTERY AND WASH AND CLEAN ALL UNDER AND AROUND THE BATTERY TO REMOVE THE ACID STUFF. AFTER THAT THE TAILGATE WHERE THE THIRD BRAKE LIGHT IS, STARTED MAKING NOISES EVERYTIME I OPENED IT, WHEN CHECKED I FOUND THAT THE PART WHERE THE REAR WINDOW IS AFFIXED TO THE TAIL GATE WHERE BROKE AND THE ESCREWS ARE HANGING BY IT SELF WHICH MADE THE REAR WINDOW LOOSE AND STANDING OUT, AND ABOUT A WEEK AGO NOW THAT I HAVE 61K MILES IN 2009 THE REAR BRAKE LIGHT WENT...

I BACKED OF THE GARAGE AND HEARD A LOUD NOISE. AS I PULLED FORWARD THE TRUCK MOVED VERY SLOWLY FOR HOW FAR THE GAS PEDAL WAS PUSHED. I WENT TO GO IN REVERSE AGAIN BUT THE TRUCK WOULD NOT GO INTO REVERSE AND COULD HEAR A LOUD WHINING FROM THE MOTOR. I THIS JUST HAPPENED TO DAY BUT I FIGURE IT'S THE TRANSMISSION. ALSO, WHEN I BOUGHT THE TRUCK I HAD PROBLEMS WITH THE TEMP. SENSOR AND THE AIR CONDITIONING THE DEALER TOOK CARE OF THE PROBLEM WITH THE AIR BUT THE OUTSIDE TEMP. SENSOR IS STILL BROKE. I DON'T KNOW WHICH IS WORSE THE FAILURE OF THE TRANSMISSION OR, SEEING ALL THE LIKE COMPLAINTS ON THIS SITE WITH NO ACTION. *JB
