2005 GMC Envoy XUV Questions & Answers
My dim headlights went out. What can I do? Has anyone else experienced this problem?
For more than a decade, GM used wiring for the headlights that barely met the amperage requirements for stock headlights. When owners replaced stock headlights with upgrades, the wires would simply fry.
The only real solution is to run NEW 10AWG (or 8AWG) wires from the headlight switch (or automatic headlight relay) all the way to the headlight connectors. (You can follow the extant routing of wires.) Best of luck to you!
Can you tell me what
Firing order is 1, 5, 3, 6, 2, 4. Number 1 cylinder is up front. Why would you need the firing order, this engine does not have plug wires, each plug has its own coil pack, each coil pack is controlled by the computer.
