Six problems related to headlight switch have been reported for the 2004 Chevrolet Trailblazer. The most recently reported issues are listed below.
On June 11 2016 at 5:00am while driving my headlights went out, I used my high beam to return home from by pass highway 15miles. Once home tried the manual switch to see if lights would come on . No low beam but high beam worked. Couple of days later at dealership they could not find anything. I notice on occasion the low beams were not on when driving with the daylight running lights when I pull behind a car I would switch to high beam which did work. On 18oct 2016 time 7:45 the lights low beam did not come on when starting my truck. I tried the high beam and it worked. Had to drive 10 miles on city street to get home on high beam. After getting home I played with switch switching from manually to running the low beam came on afte I turned the car off and back on with light on the manually position. Please help dealer can't find the issue or duplicate it neither can I. . I travel alone and female I can't have this happening. I have to get repaired. On.
The headlights will turn off while the vehicle is in motion for no apparent reason. This has been occuring for several years. You can switch to the high beams and the high beams will work. After about 10 to 15 minutes of driving, you can put the lights back to normal and they will operate on the low beams. It may be a month before this occurs again.
The contact owns a 2004 Chevrolet Trailblazer. The contact stated that while driving approximately 75 mph the low beam headlights suddenly failed. The contact quickly turned on the high beams and continued to drive the vehicle. After stopping the vehicle the low beams lights were switched back on and operated as normal. The contact indicated that the failure occurred on multiple occasions. The vehicle was not diagnosed or repaired. The manufacturer was informed of the failure. The failure mileage was 84,000.
I bought this car about 4 years ago and it has been nothing but an elecitrical mess. First my head lights would go out once a month, then a couple times a month, then once a week. My brake lights started doing the same. Our famliy mechhanic couldn't figure it out, he just kept replacing them and sending the bad bulbs in for warranty. A couple times the pigtails and lamps had to be replaces. Also 3 seperate occasions both headlights went out at once while driving. And I had to drive home in the dark with no head lights on. I took it the chevy dealership after the third time abd apparently my fuse box was melted and needed to be replaced. Spent over 1000. 00 doing that and it worked okay for about a year. Then headlights started going out again and brake tlights as well. Not once a week, but still about once a month or every other month. Recently my drivers window stopped working and I couldn't control the master switch to lock my car or roll up my windows. The cluster panel in the door needed to be replaced. Also, had two sensors that needed to be replaced because my 4 wheel drive, parking brake, and crusie control would stop working all at once and the lights would be lit up on the dashboard. I wasnt' able to use any of them until the sensor was replaced. Also the power shorted out in my side mirros, so I can't adjust the mirrors with the control or they start tiliting back and forth like crazy on their own. I have to get out of the car and adjust them manually. Gm needs to do a recall, this car is not safe and I will not be buying a gm car while I look for a new car soon.
I have a 2004 chevy Trailblazer; while driving on the highway; all guages, lights, etc. Abruptly stopped working and continue to not work. I researched on line and found it could be what is called the "cluster board". I took my vehicle to a local chevy dealer in daytona beach FL. They insisted it was the ignition switch. They replaced that mechanism for just under $300. The following week (this occurred in 2010); the exact same situation recurred; so I brought it back to the dealer and they then agreed it was the cluster board which would now cost me close to $700. 00. In order to avoid being ripped off to the tune of almost $1k; I purchased a gps unit so I could at least monitor my speed. The speed/rpms never register correctly; however, so far the other guages seems to be ok (except for the oil pressure, it goes out of whack frequently so I just bring it in quickly to make sure I have sufficient oil and that it's clear/clean). Most recently my headlights just go out without warning; I am able to use the high beams, but of course that puts me in jeopardy of getting a ticket. There are so many complaints on the 2004 chevy Trailblazer - I do not understand why there has not been a recall on the cluster board and the electrical issues (lighting). I cannot afford to have all the repairs completed and would like to see Chevrolet take on some responsibility for the cost of these flaws in the manufacturing of this vehicle.
The low beam headlight quit working after further investigation found all fuses to be in good working order as well as all relays and the dimmer switch, after checking the bulbs in the low beam assembly the bulbs were not charred or burnt and the filament was still in contact as normal, after reading some excerpts on another website this is an all to familiar incident. Luckily we were not driving at night and no one was injured thankfully. Its time for a recall before someone is injured and or killed from this type of manufacturing malfunction.
