How to solve the problem that the oil-gas conversion switch does not light up?

[AlanaAnn]

Open the driver's door of the car. Step on the brake pedal to prepare to start the engine; press the one-button start key of the car. All the dashboard lights come on, and the engine starts. Press the top of the toggle lever located on the right side of the steering wheel, hold it down for more than 5 seconds without releasing, and the matching will be completed.

When the fuel switch indicator light is off, I usually start by checking the simpler possibilities first. It could be a burnt-out bulb, which is quite common, especially after prolonged use of the switch. You can try replacing it with a new bulb yourself—it's not too difficult. Another possibility is a blown fuse; locate the fuse corresponding to the gas system in the fuse box and check if it's blackened. If replacing it doesn't help, it might be a wiring issue, like a loose plug or a short circuit. I'd gently wiggle the plug to see if there's any response. Sometimes, the switch itself is faulty, or there's an unstable system voltage. For safety, don't force it—it's better to take it to a repair shop and let them diagnose it with professional tools. It's a good habit to regularly check this area to avoid sudden issues while driving at night.
