Headlight Switch problems of the 2006 GMC Envoy

One evening while driving my vehicle on the highway, my headlights cut off. At first I didn't realize it until everything just appeared darker than usual. I had to switch to my high beams to finish the travel to my destination. This has happened continuously since then. Lights will come on at the start of the vehicle but shut down in no specific amount of time. I have taken it to three mechanics including a gm dealer and the vehicle lights stayed on during diagnosis. As of last night the lights did not come on at all. I will be returning to the dealership in the a. M in hopes that I may find a diagnosis and the solution. I can no longer drive my vehicle at night because I have already been pulled over by the police for this issue.

The contact owns a 2006 GMC Envoy 360. The contact stated that there was an intermittent electrical short that was progressing and caused the headlights to flicker for the low beams, high beams, and the daytime running lamps. The vehicle was taken to a mechanic who replaced the dimmer switch, but the failure recurred. The vehicle was also included in NHTSA campaign number: 14v755000 (exterior lighting). The dealer was unable to determine when the part and the permanent remedy would become available. The vehicle was not repaired and the contact continued to experience the failure. The manufacturer was notified of the failure. The failure mileage was not available.

While driving on the expressway at about 11pm, going 70 miles per hour, my headlight just went out. I turned the control switch on and off to see if they would come back on but they didn't. I pulled onto the side of the road and check to see if my other lights were working (blinkers, flood lights, brights) and they were. My headlights however weren't. I tried turning the truck on and off to see if they would come back on but they didn't. After sitting there with the car off for about 10 minutes, I started it back up and they came on. I had to turn around and go back home in fear that I couldn't finish my trip because I didn't know if my lights would go out again. Since this first incident, my light go out on a daily basis and at random. They have gone out while my truck has been in park as well as while I've been driving. I have taken it into the shop and after them having my truck for 9 hours, they told me they worked the whole time while they had it (go figure). I took my truck back in this morning because it was happening again and I was able to show to them that my switch was registering my headlights as being on when they weren't. I have contacted GMC to file a complaint and was told at this time there wasn't much they can do and that I just need to get it repaired. Hard to do when no one will acknowledge the problem. I am beyond frustrated because I am limited when I can drive my vehicle due to this major issue that can happen at anytime without any warnings.

Safety issue: while driving home last night both low beam headlights went off. Pulled over and stopped the vehicle as it was dark. Turned head light switch on and off, but could not get lights to work. Bright lights worked and so did driving lights, therefore I drove on home. I checked the GMC web site and found no callbacks. However under problems with Envoy vehicles from general motors there are reports that this same electrical problem is being considered for a callback.

One evening I was driving on the main highway and my inside lights came on. I pulled to the side of the road to check the switch but it was on auto. I turned it off but the lights stayed on. They were still on when I got home and parked turned off the ignition the lights were still on. The next morning my car couldn't start because it had ran my battery down. Another incident was my headlights went off one night while I was drive on the highway. I am also having problems with my gas gauge. My gas light comes on like I am out of gas. The last time I fill my car up with gas it hesitated. It didn't want to start. The light stays on when my car is full of gas. I smell gas. I sat at the gas station for an our because my car didn't want to start. The sound of my radio goes in and out. My lights continue to go on and off when driving or when not driving. One morning I got up to go to work, went to start my car and the headlights were on but the switch was off. I couldn't get the lights to go off when I got to work. They stayed on at least for 4 hrs. Sometime the lights doesn't come on when I put them on. I really have some weird things go on with my vehicle. I did get the module changed and they did some re-wiring in the door. One year before the module, I got them to check my car for a short and I was told from them that my wires were over heated. I paid about $900 to fix it. I strongly think it is a detect some wheres or something that would cause my wires to over heat.
