Dim lights are flickering not wanting to stay

- St. Paul, NE, USA

About 4 years I noticed my low beam headlights sometimes would not work at night, forcing me to drive with my high beams on, blinding other motorists. This was reported to the dealer's service manager and he said it may cost $500 to determine the cause. I could not afford this expenditure. I try to avoid driving at night and only recently I had to drive at night and again my low beams would not work, forcing me to again drive with my high beams on. My fianc did a google search and learned this is a common problem with this fuse/relay. We learned we could pull out the high beam fuse/relay which is identical to the low beam and switch them. Upon doing so, the low beams once again worked.

I had just drove my truck the night before headlights worked fine. I went to leave the next night and no headlights at all. So vehicle was stationary when I realized I had no headlights. I have to drive with my brights on at night. I have no regular headlights at all. Then my passenger side window just quit working as well.

While driving, low beam headlamps will turn off without warning...high beam headlamps still function

- Columbia, SC, USA

A while back, we noticed while driving down the interstate at night that our lights seemed to be flickering (low beams). It would do it occasionally, but we never knew when it would happen. Since then, we have had the lights go completely out while driving, and had to turn the fog lamps on to have headlights of any sort. Tonight, the lights went out, and I pulled into my driveway and was going to have my husband come out and see what was going on if he could. While I sat there with the car running and in park, after about 3 minutes, they came back on. I have read that there was a recall on the light modular for 2006+ Envoy, but mine is a 2005, and having the same problem that I heard the recall was for. I have also heard that the 2005 trailblazers were included in the recall, but not the Envoy"??"

The low beam headlights went out while driving 50mph on a highway because a relay in the fuse box overheated and melted the fuse box. I know there is already a recall on the trailblazer from the same year because they are the same car but there is not one for the Envoy.

Low beam headlights go off without warning. High beams still work. This has happened when moving on city roads and highways. The next time I drive the car the low beams may or may not work.

The vehicles headlights keep going out at night will driving. I have been dealing with this problem for about 2 years, I am a certified mechanic and I believe the problem is the headlight relay that is overheating. This is the same GM part that is being recalled in other GM vehicles. GM part # 15016745. So why has it not been recalled in 05. The problem happens at random the light will go out while driving or parked it does not matter.

I've had my 2005 Envoy for a little over a year and had my headlights flash on and off while driving on the road and freway. On one occasion while driving on a two lane highway ay night the lights went out completely for a few seconds. I was so scared wss really glad for no one behind me or on coming traffic. On another occassion I had to pull over on city street as my lights were going on and off and I could see the car ahead was a cop and I didnt want him to think I was flashing for help especially at 2 in the morning. Ive also had to exit the freeway because my lights started going on and off and on and wasnt sure if they would just go out completely while I was driving and since it was night time I didnt want to take the chance of causing an accident and hurting someone else or myself. I have a teenage daughter and am afraid to Transport her and her friends in my car.

Reading numerous complaints that compare to mine the fuel gauge, oil gauges, air conditioner are all malfunctioning in my car and I'm very upset because all of this should have been recalled. I purchased my car brand new in 2005 and I will never buy a GMC car again for this reason it's one thing to recall repair parts that were broken that to repair malfunction parts. Very disappointed. In short my gauges don't work, my air conditioner only works on one side and now my headlights low bean don't work. GMC needs to recall and repair.

Lights go off and won't come back on for 2 hours. You can smell something burning but cannot find where it is coming from. I have replaced all bulbs 3 times. And nothing changes.

I was driving down the highway after dark and my low beams completely went out. I could only get my high beams to work. Currently only one low beam is working and the other will not work even after changing the bulb or the fuse. I believe this is a huge safety concern especially having a young child. It was very scary going down the road at night and have your lights completely just go out. I have noticed that there are issues with 06-07 Envoy but I wanted GM to be made aware that 2005 models have been affected as well.

I was driving on a curvy 2 lane road in the country and the sun was just setting and I couldn't get any lights on my car. My lights are automatic and I just assumed that I had bumped a button and accidentally turned them off, so I started turning the switch to turn them on and it wasn't working. I almost drove off the road several times trying to get some light on. I then hit a section where tree lined curved section that was pretty dark. There had been no shoulder or anywhere to pull over there or for several miles. I could get bights lights, but no dim. I ended up driving with my fog lights, unknowingly at the time. We had just replace the bulbs 5 months before but we tried new bulbs and fuses to see if this would fix the problem. Unfortunately, it didn't. I have noticed a recall on lights for the Envoy years 06-07 for what seems like the same reason and mine is an 05.

As I was driving the vehicle, the dashboard lit up and the odometer and all the information systems went to zero. This has happened often over the years. I took it to two GMC car dealerships and the first one said it was the kill switch installed by a buy here pay here dealership. The kill switch was removed and the dashboard continued to flicker. Then the car would not start, I took it to another dealership and was told they couldn't find anything. The car began to tribble, again I took it in and was told that I needed to clean the fuel injection system. I did that and bought a battery but that didn't help. The tow driver said it seems to be something electrical but the car dealership can't find a solution. Have you had this complaint before? not to confuse the complaint, I have several issues. 1. dashboard lights up and the information panels shut down (all are at zero) 2. the odometer goes to zero and the instrument cluster is black 3. tribble underneath while driving feels as if the car is shaking thank you for any assistance you can provide.

The first day we had the truck the speedometer displayed the wrong speed and has been that way. It works occasionally. Then a week later the low beam head lights went out while driving. They came back on after a few mins. This happened again a few days ago. The fuel gage is in accurate as well. I took it to a shop and they said the instrument cluster needs to be replaced but found no issues with the head lights but there is definitely an issue with the headlights and that is very dangerous.
