What are some common issues with the Vauxhall Astra's electrical system?

I have been experiencing problems with my Vauxhall Astra's electrical system. The car intermittently won't start and the headlights flicker. What could be causing these issues and how can I fix them?

First, check the battery connections to ensure they are clean and secure. You may also want to have the battery tested to make sure it is holding a charge. If those things check out, the issue could be with the alternator or a loose electrical wire.

It's possible that water has gotten into the electrical components of your car. Check the fuse box and any exposed wiring for signs of moisture. If you find any, dry it out thoroughly before attempting to start the car again.

Another common issue with Vauxhall Astras is a faulty ignition switch. If none of the other suggestions fix the problem, it may be worth having a mechanic take a look at the switch.
