While driving the dim lights turn off by them selves. Now they will not turn on at all. I have replaced relays and fuses. No help.

When driving vehicle both left and right low beam headlights go out. The first time it happened was when I was driving long distance in the dark. Had to drive with my high beams on for the rest of the trip. There is no specific time frame, but generally it happens anywhere from 10- 30 minutes of driving. I suspect it is heat related. I have changed the headlight relay #46, bit it only fixed the problem for a week. Again the lights will go out after driving several minutes. I noticed there is a recall for a similar issue on the 2006 Chevy Trailblazer. Could this be the same problem with my vehicle. There are also multiple forums explaining the same exact issue with early 2000 model Trailblazers. This issue happened approx 6 months ago. Last week we ran into another problem. Our ABS light comes on periodically. Like the headlights going out, the ABS light comes on after driving the vehicle for a certain amount of time anywhere from 10 minutes to 30 minutes. Again, I feel it electrical components/wiring is overheating and causing these issues. I feel there should be a safety recall for this this issue as it is affecting hundreds of customers usa wide.

While driving several times the head lights have went out or dimmed a lot.

This vehicle has the same problem with the headlight relay. The headlights go out on dim occasionally. The lights will also stay on when the switch in shut off. They will also come back on after going off when the switch is off. There is an active recall for 2006 models with this issue but none for the 2005. This occurred while driving the vehicle.

I bought this car used in 2009. It had about 60000 miles on it. 1) the first problem I had with it was a burnout of the hac blower plug, that part of the wiring harness had to be cut out and replaced wth a completely new plug( both halves) and rewired in for a cost of 125.oo and 3 hours of labour. I looked this up on the internet very common problem 2) rider side door control panel stopped working with strong odor of burnt plastic. Again looked up and found there was a recall, but only 2006 vehicles 3)brakes burn out of rotors only on rightside- left side rotors were fine, brake job with replacement of 2 left rotors I front piston amd all 8 pads $650. Failure occurred while driving on city street 4) failure of ignition switch with erratic electrical function of running lights, radio and dashboard instrumentation. Happened on the road early twilight very dangerous had to get a local toll for $75 all of these failures have made me very wary of driving this vehicle. They occurred at various times over last 4year some have been repaired as noted above. Presently waiting for igniton system repair.

Passenger low beam headlight has gone out several different times over the 5 years we've owned it. Had a relay switched out that helped for a little bit. Also had to change the wiring right by the headlight because it was burnt up. We took it to Chevy in devils lake, nd. I seem to notice other Trailblazers driving around with the same headlight burnt out.

Day/dim lights kept going off while driving at dark. And now they wont come on at all. Having to drive with brights on. Just wandering what do I do. Or how much would it cost to fix it. Im tired of getting bright lighted from other cars that I pass. There's been a recall for this particular problem but my vehicle is not on there. Not sure on the date below, just and estimate.

The headlights and gauges keep dimming while driving.they will flash.the headlights will go off completely and then come back on after a minute or so.it is very dangerous when the headlights go off while driving at night.I have seen several complaints of the same trouble.the 2006 models were recalled for this problem but the 2005 models were not.why when they have the same dangerous issues?this needs to be recalled and fixed before someone is killed by the lights going off causing a wreck.this problem has happened allot every since I purchased this Trailblazer several years ago.

Occasionally headlights go out at night while driving. I see that 2006-07 were recalled but many others with a 2005 also complained of the same issue I'm having.

- Granger, IN, USA

The low beam headlamps fail simultaneously. This occurs while driving at night. I have replaced the hdm solid state relay twice, but after a time. 6 months to a year, the failure occurs again. Once the hdm module became to hot to touch upon failing. This last time, the third, the lights may come on again after some time has passed. It is as if the module is short circuiting or overheating leading to a short circuit.

2005 has the same headlight malfunction as the 2006 headlight go out by themselves, thus causing a unsafe condition on the hwy. They should be on recall too. This has happened 4 times since I 1 owner had vehicle.

While driving at night, low beam headlamps go out completely. High beams still work and are the only option for getting home. Has happened multiple times. The first time it happened we were traveling away from home. We were on the highway and realized that we had no headlights. Very dangerous situation and from looking online - this seems to be a very common problem without a solution. Shop can't help unless they are doing it at the time.

The contact owns a 2005 Chevrolet Blazer. While driving at approximately 30 mph, the low beam headlights were activated and illuminated intermittently. The instrument panel warning indicators also illuminated. In addition, the high beam headlights experienced the same failure when activated. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 150,000. The VIN was not available.

Headlights go out while driving at night. Very scary

Low beam lighting was out when the vehicle was turned on at 2030. It did not come on while driving (20 minutes) so I had to use the high beams. I did check multiple times while driving.

I was leaving a parking lot at dark and my low beam headlights were working. After exiting the parking lot to the road, I note that the low beams were out. I then had to drive through town on the busiest roads with my high beams on. It was approximately 2100 and the temperature was in the 70's.

While driving after dark, the low beam headlights went out. The high beam lights continued to work. This is a recurring issue and seems to occur more once the vehicle has been running for some time. The lights did not come back on until the car was left parked overnight.

While driving southbound on I-75 in Michigan at approximately 9:10 pm on August 16, 2015, the low beam head lights went out near mile marker 180. The high beam lights and running lights continued to work. The low beam lights remained off until after I exited I-75 at the southbound 155 exit. After leaving the exit and driving an additional 4 miles, I again tried the low beams and they worked. I later got back into the vehicle (after it was off for approximately 30 minutes) and the low beam lights were again off. They would not come back on and I left the vehicle. The following morning, the low beam lights were functioning again. This situation has been reported to the executive customer service office at GM and they have stated that there is not a current recall and therefore they will not repair it.
