Weird electical fault

[sparkyscfc74]

Hi there,

Would really appreciate some help with this one, my Astra J has developed a weird electrical fault. Most of the exterior lights have stopped working except for the middle brake light and high beams, the interior lights have stopped, the central locking, fans and rear window washer as well. This all happened at the same time, I get lights on the dash saying that I need to check the bulbs but that doesn't make sense with everything stopping at once. I've had it to a couple of garages who have both said it's the fuse box, but Vauxhall want around £700 to replace this.

Is there anything else that it could be? I've going to try and take the fuse box out and spray with WD40. Also, my car was serviced about 10 days before this happened - when I took it for the service I had a message on the dash to check one of the daytime running lights, this message went after the service but the bulb was never changed. Could that have anything to do with it?

As Rusty says go through every fuse as this seems very similar to what I’ve just gone through and thought it was the body Control Module. It’s surprising how many different components one fuse can control and not listed in the handbook!!!
Hope you get it sorted
