Having problems with your GMC Envoy XL ?
I have a 2004 Envoy XL. The passenger side dim headlamp went out about 2 weeks ago and I replaced it. On Friday, I was leaving a meeting and I noticed my neither one of my headlamps were on, then I hit a bump and they came on. This evening, I was leaving to go somewhere and got in my Envoy, turned the lights on and neither dim headlamp came on. I tried changing the fuses out but still nothing. High beam headlamps work, parking lights work and fog lights work, but my low beams do not. What could
Had both low beams go out on my 04 Envoy about 5 years ago. Don't have the service receipt but IIRC it was a bad module that controls the lights. The dealership replaced it for free even though my vehicle was out of warranty
This sounds like a loose connection/bad wire somewhere for the low beam lights. Can't really give you more information without seeing the vehicle, and wiring diagram for the circuit. Usually, things that go on and off when hitting bumps are connection/wiring problems. The fact that one of your low beam headlamps burnt supports this theory. Bad connections or wiring mean lower voltage, thus higher amperage at the bulb, motor or whatever it's running, which makes them burn a lot quicker.
