4 Fog Light Switch problem

Failure Date: 09/25/2015

While driving on the inter state at 8;30 pm both the low beam headlights failed I moved the light switch from auto to manual with no affect. The fog lights and high beam lights continued to work. However using the high on the interstate could affect on coming drivers so where the highway was lighted I used the fog light. Got home off interstate using high beams. Next morning the daytime lights and low beams working however shortly after driving to store the lights again were not operative stopped at pep boys and asked them about it and they said they could make sure bulbs were okay but normally both bulbs don't fail at the same . Later in the afternoon tried lights and both daytime and low beams worked. A friend told me gm was having trouble with 2006 and 2007 trail blazers with the light just shutting off and a module was believed to be problem. Apparently gm has known about this problem and was suppose to recall the vehicles yet they did not warn anyone one about this issues however people with earlier trail blazers have been having problems also. Even if gm is trying to decide on a recall fix they and the government should mandate that they at least warn the vehicle owners and tell him how to fix the problem. I have have not received any notices about the low beam lights as a point of reference my lights failed on an over pass down ramp and caught me totally by surprise thank god it was not a two lane secondary road with on coming traffic. Its time to force gm to deal with the problem. I am taking car to the local dealer to see how they deal with it. I have also seen on the internet you can get a module at local auto parts store I am looking into this tomorrow since I live in florida and soon it will be dark at 5 o"clock and I will be constantly driving home in dark on the interstate.

5 Fog Light Switch problem

Failure Date: 04/10/2015

I was driving my truck heading home and noticed the road looked dark. I pulled over into a parking lot and realized I had no low beams. My blinkers, fog lights and high beams all worked properly. I had to drive home with my high beams on, blinding other drivers. My headlights and daytime running lights have intermittently went out off and on (approximately 4 times) over the past year. I had the dealership look into it the last time I was there and they couldn't find a problem. When researching what could cause both lights to fail at the same time, I came across the latest recall info. I called chevy and gave them my VIN and was told my vehicle is not affected by this recall. Strange, since I have all the exact same problems listed in the recall and my vehicle has been affected by all of the other recalls on it so far.

6 Fog Light Switch problem

Failure Date: 05/01/2013

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. I was positive that my vehicle was included in the recent recall, but when I called my local dealer, I was advised that my VIN number was not included. I don't understand, since the issue on the recall is exactly the issue that I am dealing with. I have had to limit my use of the vehicle at night for fear that the headlamps will fail. Side note - they have failed at night twice in the last week alone. Generally what I have to do is pull over on the side of the road (scary) and turn the car off, wait, and try them again.
