2009 Chevrolet Trailblazer headlight problems

EXTERIOR LIGHTING

My first complaint is that headlights, low beam, would not work. Only high beams worked. The issue stopped, unexplainable, on its own, has not occurred again. The 2nd complaint is the radio volume would 'slip' as if there were a loose wire to the speakers, and loss of sound became more frequent and for longer periods of time, eventually all sound stopped, it has not been fixed, as of yet. 3rd complaint, a brand new battery, in under a year of use, went completely dead, without any visible explanation. When an attempt to jump start the vehicle the cables from another cars battery were touched at my cars battery, it sparked, indicating to the person performing the task, there is a 'short' somewhere in the wiring system. I drive this vehicle less than 3000 miles per year, and use it sporadically with my second vehicle to keep the batteries active. I cannot explain why these issues are occurring but thought it important to mention them to other possible victims with the same issues.

THE LOW BEAM HEADLIGHTS KEEP GOING OUT. ALL OTHER LIGHTS STAY ON AND THE HIGH BEAM LIGHTS WORK. ONLY THE LOW BEAM HEADLIGHTS ARE AFFECTED. THIS HAS HAPPENED WHILE IN MOTION AND FROM A STOPPED POSITION WHEN FIRST STARTING THE CAR AND PUTTING IT IN DRIVE. I HAVE RESEARCHED IT ON SEVERAL GROUP WE SIGHTS AND FOUND THAT THE PROBLEM IS THE HEADLIGHT DIMMER MODULE (HDM). I HAVE REPLACED THIS TWO TIMES OVER THE LAST TWO YEARS WHICH ALWAYS FIXES IT FOR ABOUT A YEAR THEN IT STARTS FAILING AGAIN. THIS IS A VERY DANGEROUS SITUATION BECAUSE IT HAPPENS AFTER DARK. I CAN PULL OVER AND STOP, OPEN THE HOOD AND TAKE OFF THE FUSE BOX COVER AND REMOVE THE HDM AND PUT IT BACK IN THE SOCKET. SOMETIMES THIS WORKS AND SOMETIMES NOT. IT IS A DANGEROUS SITUATION. THERE HAVE BEEN RECALLS ON EARLIER TRAILBLAZERS BUT NOT THIS YEAR. IT SHOULD BE INCLUDED.

THE HEADLIGHTS HAVE FAILED. ALL THE LIGHTS BLINK WHILE YOU RIDE ALONG. THE TWO BACK DOORS WILL NOT LOCK OR UNLOCK AND THE FRONT DOORS ARE STARTING TO NOT LOCK OR UNLOCK PROPERLY. THE ITEMS THAT LET YOU KNOW WHEN A TIRE IS LOW IN AIR ARE FAILING. THE LAST ONE COSTING OVER $100 TO FIX. I AM GETTING VERY UPSET WITH THE ELECTRIC PARTS IN THIS TRAILBLAZER. THIS HAS BEEN GOING ON SINCE PURCHASE. AS A PHOTO I CAN SEND YOU A PHOTO OF THE VEHICLE.

I JUST SAW THE RECALL GM IS DOING FOR THE 2006~2007 CHEVROLET TRAILBLAZER. I NOTICED THAT OTHER YEARS ARE NOT AFFECTED SPECIFICALLY MINE. MY 2009 TRAILBLAZER CURRENTLY HAS THIS ISSUES, BOTH LOW BEAM HEAD LAMPS DO NOT WORK. I HAVE TRIED EVERYTHING TO GET THEM TO WORK. I HAVE HAD NO LUCK. PLEASE INVESTIGATE THIS ISSUE FURTHER. WE HAVE TO DRIVE WITH OUR HIGH BEAM LIGHTS WHICH COULD POSSIBLY CAUSE AN ACCIDENT. THANK YOU
