Headlights low beam randomly turn off during night driving. When using turn signal the headlight high beam turns-on and cannot be turned off with switch, the only way to turn-off high beam is to press forward on turn signal.

The low beam headlamps randomly turn off while driving. We have tried using the auto setting, and the "on" setting and it happens either way. The lamps are fine, the fuses are fine, the wiring is fine. We are unable to locate the problem. This makes the car nearly impossible to drive at night. It is very dangerous to be doing 55 mph and have this happen.

A couple of months ago (April maybe) as I drove home from bible study the road suddenly became very dark...as the road is in a poorly lit Suburban area I noticed the difference immediately and flicked my light switch in the car at which time the lights came back on. I thought to myself, 'that's odd', but really did not make too much of it. (it was a typical rainy spring night in va and the road I traveled is extremely dark with headlights and curvy, luckily I am familiar with the bends and twists as I travel the road at least four times a week. I shudder to think of what could have happened if a less experienced drive or someone less familiar with the bends and twists of this ditch lined road had been driving when the lights suddenly and inexplicably stopped working). A couple of weeks ago, again as I left bible study, my low beams stopped working again. I was still in the parking lot at the time so I got out of the car to be sure and several church members also came over to see what the problem was. This time, the low beams did not come back on. I drove home with my high beams on and hoped the issue would resolve itself by morning. Alas, it did not. I began the quest to find the problem and was told that the problem was the fuse box...it was not. I was told that the problem was the actual switch...it was not. Finally, I took my car to tidewater auto electric and they diagnosed the problem as follows....removed BCM to pin check. No output from BCM to low beam relay module. Checked resistance from BCM to fuse box all wiring ok. Needs BCM replaced also needs low beam relay module. It was explained to me in laymens terms that the computer was bad and had to be replaced and that the signal from the light switch to the fuse box was bad as well and had to be repaired. This repair cost me $694.07 for a vehicle that is just over two years old. This defect seems to be something worth looking into as it could prove extremely hazardous in certain conditions.

Driving home on memorial day, night through traffic, people yelling to turn "turn your lights on". my lights on my 2007 Pontiac Grand Prix are automatic. I have driven my car all week long only to find out that I do not have any headlights. The fuse block has gone bad and my low beams do not work. There is no alarm, notice that goes off to tell me this. My lights when I turn them on manually do not say that they are not working. Everything appears to be fine in side the car. You just have not headlights, low beams, only high beams.
