LOWERED THE DRIVER'S POWER WINDOW & IT DIDN'T GO BACK UP. OPENED & CLOSED DOOR & TRIED BUTTON A FEW MORE TIMES, THEN IT WENT UP. UNSURE OF BURN SMELL AS I WAS ON HIGHWAY. CHECKED AGAIN WHILE STATIONARY & WINDOW BUTTON NON FUNCTIONAL. NOTED THAT INTERIOR DOME LIGHT DID NOT LIGHT WHEN DOOR OPENED & ALL POWER BUTTONS IN DRIVER'S DOOR (WINDOWS, LOCKS, MIRRORS) RENDERED NON-FUNCTIONAL. ALSO NOTED THAT THIS DOOR DOES NOT RESPOND TO REMOTE KEYFOB FOR LOCK/UNLOCK, AND DOOR BY-PASSES ALARM SYSTEM. ALARM CAN BE SET, DOOR OPENED WITH KEY AND ALARM WILL ONLY TRIGGER WHEN KEY IS PUT INTO IGNITION, BUT UNARMS WHEN IGNITION CRANKS. IT SHOULD ALSO BE NOTED THAT THE DRIVER'S DOOR IS THE ONLY DOOR THAT HAS A KEY LOCK MECHANISM. THE REST OF THE VEHICLE RELIES ON REMOTE OR DOOR SWITCHES. APPROXIMATELY ONE YEAR LATER I OPENED THE DOOR (AS I COULD NOT PUT THE WINDOW DOWN) AND THE INTERIOR DOME LIGHT LIT, SO I TRIED THE POWER LOCK BUTTON AND IT WORKED. TWICE. THE ENTIRE DOOR AGAIN WENT DEAD/NON-RESPONSIVE. WITHOUT WINDOW ACCESS, THE DOOR MUST BE OPENED ON HIGHWAYS WITH TOLL BOOTHS. THE LACK OF INTERIOR LIGHT, INABILITY TO READILY ACCESS THE DOOR LOCKS, AND THE ALARM BY-PASS CREATES A SECURITY ISSUE. THE INABILITY TO ADJUST THE MIRRORS CREATES A SAFETY ISSUE, AS THE WINDOW CANNOT BE LOWERED.THE DRIVER'S DOOR NO LONGER LOCKS WHEN THE VEHICLE IS PUT INTO DRIVE. THE SCARIEST THING IS THAT THE CONTROLS SIMPLY STOPPED. WHY? A SHORT IN THE SYSTEM IS A VERY LOGICAL POSSIBILITY, ESPECIALLY WITH THE RANDOM FUNCTIONING JUST A YEAR LATER. I HAVE NOTED MULTIPLE ISSUES ON REPAIR SITES REFERENCING THIS PROBLEM WITH 2005 TRAILBLAZERS, AND AS OF TODAY (6/15/13) SAW A RECALL FOR A SHORT IN THE DOOR FOR 2006/7 TRAILBLAZERS. IF THE SAME ISSUE IS OCCURRING WITH OTHER YEARS, WOULDN'T IT FOLLOW THAT IT WAS A FLAW THAT SHOULD BE REVIEWED IN ALL TRAILBLAZERS OF THE SAME BODY STYLING? *TR

THE CONTROLS IN THE FRONT DOORS FOR THE WINDOWS STOPPED WORKING. THERE WAS A SLIGHTLY BURNT SMELL WHEN I GOT IN THE CAR THAT DAY. NOW THERE IS A CLICKING SOUND IN MY DRIVERS DOOR THAT HAPPENS ABOUT EVERY 35-45 SECONDS EVEN WHEN THE VEHICLE IS TURNED OFF. WHEN THIS CLICKING SOUND OCCURS WHILE THE VEHICLE IS RUNNING MY ENGINE LOSES POWER. THIS IS ALSO KILLING MY BATTERY EVERY NIGHT BECAUSE IT IS OCCURRING EVEN WITH THE VEHICLE TURNED OFF WITH NO KEYS IN THE IGNITION. I AM AFRAID IT IS GOING TO START A FIRE IN MY DOOR. THERE IS ALREADY A RECALL FOR THE 2006 AND 2007 FOR THIS EXACT SAME ISSUE. 2005 NEEDS TO BE ADDED TO THE LIST BEFORE SOMEONE GETS HURT. *TR

WHILE DRIVING DOWN THE HIGHWAY, THE DOOR LOCKS BEGAN TO OPERATE INTERMITTENTLY, LOCKING AND UNLOCKING. THE DOOR LOCKS ALSO OPERATE WHILE PARKED IN THE GARAGE AND THE VEHICLE IS OFF. THERE IS A BUZZING SOUND IN THE DOOR AND THE LOCKS HAVE COMPLETELY DRAINED A RATHER NEW BATTERY. A NEW BATTERY WAS INSTALLED, BUT THE BUZZING AND THE INTERMITTENT OPERATION OF THE DOOR LOCKS CONTINUE. I WAS TOLD THERE WAS A RECALL ON SOME VEHICLES FOR THIS SAME PROBLEM, BUT GM TELLS ME THERE WAS NO RECALL ON THIS PARTICULAR VIN. DURING A CALL TO GM, I WAS TOLD THERE WAS A "RATHER LARGE RECALL" PENDING THAT WOULD BE FINALIZED THE MIDDLE OF JANUARY. I WAS ADVISED BECAUSE OF THE PROBLEM TO TAKE MY VEHICLE TO A DEALER TO HAVE IT REPAIRED AND GM WOULD REIMBURSE MY COST "IF IT WAS INVOLVED IN A RECALL". IN A SUBSEQUENT CALL TO GM, THE PERSON I SPOKE WITH SAID THERE WAS NO PENDING RECALL FOR THIS VIN AT THIS TIME. BECAUSE OF THE SAME PROBLEMS IN OTHER GM TRAILBLAZER MODELS, I WAS ADVISED BY THE DEALER I CONTACTED NOT TO PARK IN THE GARAGE BECAUSE OF THE POSSIBILITY OF FIRE DUE TO A POSSIBLE ELECTRICAL SHORT IN THE DOOR MODULE. *TR
