2004 GMC Envoy headlights would periodically dimm and go off during breaking. Without warning headlights failed with no indication. Repair at GMC dealer cost $130 for a "hdm relay". very dangerous failure as no fuses failed, no lamps failed, but a hidden component failed which caused me to go off a highway at high speed at night.

The truck's dim lights all of the sudden stop working. The bright lights come on, but the dim lights will not come on at all. The bulbs were checked, and the dimmer switch. I've taken it to 2 mechanics, and no one can find out what's wrong with the lights. I can't get my tags renewed because the dim lights don't work at all. I've called GMC to see of any recalls, and they stated only rear tail lights. I definitely think its a manufacturers default, and would like the issue resolved.

I have been experiencing headlights, interior lights, lighting in the dash, and other lighting flicker while driving. It appears to be happening more and more. The lights become very dim and then get bright again in a matter of a few seconds. This is getting to be dangerous as people tend to pull over in front of me and sometimes traffic in going in the opposite direction coming towards me will pull of the road all thinking that I am flashing them either due to an emergency or just some wild driver behind the wheel. I had taken my vehicle to the dealer but he states he can not find anything wrong. Of course he also stated they took it for a ride but it does not happen for them. I guess not, it is hard to see lights flickering in the sunshine.
