Five problems related to headlight switch have been reported for the 2005 Chevrolet Trailblazer. The most recently reported issues are listed below.
My headlights keep going out while driving. I have replaced the bulbs and the relay switch. They will work for a while and then will go out again. Sometimes they will come back on. I cannot drive my vehicle at night with no headlights. The bright lights will work once in a while. This has been an ongoing problem for a few years. I have not been able to get my lights back on and no one seems to know what the problem is. This is a big safety issue and I see that there are many others with the same complaint. Gm needs to do something to fix this issue. The 2005 seems to big a big issue and a recall should be issued for the safety of all drivers and passengers. The date I selected below for when this happened is the most recent.
The headlights go out without any warning, I can't seem to turn them back on, I have to pull off to the side of the road, I tun the switch on and off and nothing happens, I've had the fussed and headlights changed and I can't seem to find a solution. The seem to just go on and off on their own. This if a very dangerous issue and I have found out I am not the only chevy owner that this is an issue with this model and I's surprised to find out there has not been a recall for this unsafe defect!.
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.
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.
