2007 Chevrolet Trailblazer 360 Exterior lighting Problems

“I was going down the highway and all of a sudden my headlights cut off. I turned the vehicle off and pulled some of the fuses and put them back in. The lights came back on later. We continued down the road to our destination and the lights went out again. We ended up having to get a hotel room for the night until we could drive home during the daylight hours.”

“Driving down the road the head lamps would just go off. I would still have high beams however the lights would flicker and then come back on. They were checked and no loose connections were found but they would always come back on. Fast forward to about a month ago, I was driving home in the dark again and the lights went off but this time they did not come back on. They have been out and have not come back on since. I still have high beams but no low beams. Thank you”

“I was driving home one night about an hour after dark. As I was driving about 45 MPH, my headlights just completely went out without warning. After carefully pulling off to the side of the road I realized my high beams were still working. I looked into this issue and realized it was a relay 45 and 46 issue. The next day I replaced this relay and my lights worked. For a day. Now it's been almost a month, and I can't drive after dark. I've asked my local GM dealership to look into this and they told me there was a recall but yet they don't have a resolution. …”

“I was driving home from a wedding on the interstate at 55 MPH, and my headlamps failed. Everything went completely dark. After a panic, I was able to turn on my high beams, and they worked properly. I had to drive the rest of the way home with my high beams on for safety, blinding oncoming drivers. When I got home, I tested my fog lights, and they worked properly. I turned the car off, waited a few minutes, and turned it back on. The low beam headlamps worked then. Since the first incident, I have had approximately 10-15 other incidents of the same occurrence. …”

“Low headlights (both) are off continuually. High beams are ok, no matter which position dash headlight switch is in. High beams come on with steering column control, but not low beams. Replaced relays and fuses although originals checked ok.. Removed each headlight nacell assembly and checked each light individually with separate source 12v. All ok. Meter checked hi-lo headlight plug, 12v ok on hi wires, no voltage on lo wires. Problem exist whether car is running or not. I am stumped!”
