How to troubleshoot electrical issues in a Vauxhall Zafira Life?

I have been experiencing some electrical issues with my Vauxhall Zafira Life and I'm not sure how to fix them. The car won't start and the dashboard lights are flickering. Any advice on how to troubleshoot and potentially fix these issues would be greatly appreciated.

First, make sure the battery connections are clean and secure. If that doesn't solve the issue, you may need to check the alternator for any faults. Also, check for any blown fuses that may be causing the flickering lights.

I had a similar issue with my Vauxhall Zafira and it turned out to be a faulty ignition switch. I would suggest checking that as well.

In my experience, electrical issues can be tricky to diagnose and fix. I would recommend taking your car to a certified mechanic for a proper diagnostic and repair.
