Why are both the headlights and taillights of the Coaster not working?
2 Answers
The reason why both the headlights and taillights of the Coaster are not working is due to a blown fuse. Below is some relevant information about the Coaster: 1. Introduction: The Coaster COASTER is synonymous with Toyota's "luxury passenger vehicles," featuring a spacious and comfortable cabin, as well as a balance of economy, luxury, and overall performance. 2. Custom modifications: The Coaster has a wide range of applications, but its relatively high price makes it suitable for use as a reception vehicle, inspection vehicle, or motorhome. Since the original electronic configurations may not fully meet the requirements for special purposes, the Coaster often requires upgrades. For special purposes, ride comfort is the most critical aspect to improve, as the original Coaster seats use fabric upholstery, which affects softness.
I've been driving a Coaster for several years, and issues with both the headlights and small lights not working are actually quite common. Most of the time, it's a blown fuse, especially when both lights fail simultaneously—it's likely a main fuse that's broken. You can check the fuse box near the steering wheel; the diagram inside will indicate the positions of the headlights and small lights. If replacing the fuse doesn't fix the problem, it could be a short circuit or poor contact in the wiring, particularly in older vehicles where wires tend to degrade. Another possibility is a faulty combination switch—that lever controlling the lights—where corroded contacts cause it to malfunction. When I encountered this issue last time, it was fine during the day, but driving at night was really dangerous. I suggest heading to a repair shop for a check-up as soon as possible—don't delay. You could also try inspecting it yourself, but be careful not to get an electric shock. Simple tools can handle some basic troubleshooting.
