Common electrical issue in Vauxhall Astra

I've been having issues with the electrical system in my Vauxhall Astra. The lights keep flickering and the car sometimes won't start. What could be causing this and how can I fix it?

It sounds like you may have a problem with your alternator. This is responsible for charging the battery and if it's faulty, it can cause electrical issues like you described. It's best to take your car to a mechanic to get it checked and repaired.

Another possible cause could be a loose or corroded battery connection. This can disrupt the flow of electricity and cause issues with starting and lights. Check the connections and if needed, clean or tighten them to see if that solves the problem.

A faulty ignition switch can also cause electrical problems. This is responsible for sending power to the starter and other components, so if it's malfunctioning, you may experience issues with starting and lights. Have a professional inspect and replace the switch if necessary.
