Why are all the lights in my car blinking?

The most common reason for flickering lights is a worn out alternator, as one of the three rotating plates that generate electricity wears out. So as the unit hits the "dead spot," the power wanes, causing the lights to flicker. ... Replace the alternator if it fails to produce more than 13 volts, or tests bad.

How do I stop my headlights from flickering?

Can a bad relay cause lights to flicker?

Why do my gauges flicker when I start my car?

Why are my interior lights flashing?

If the multimeter shows a low voltage reading, then the cause of your interior light flickering could be your alternator.

How do you know if its the battery or alternator?

If your engine won't turn over or takes far longer than usual, it's time to grab the jumper cables and attempt a jump-start. If your engine starts and stays running but won't start again later, it's likely a battery problem. If your vehicle immediately stalls, it's probably a bad alternator.

How do I know if it's the battery or the alternator?

Starting and running an engine, in its simplest form, is a three-step process. ... If the engine starts but dies immediately, your alternator probably isn't keeping your battery charged. If a jump starts and keeps your car running, but the car can't start again off of its own power, a dead battery is likely your answer.
