Hi, I am new to this but I need help with my Mazda 323 1997. Every 2 or 3 months i go to use my car and the headlights dont go on, I have taken it to the garage every time and they replace the bulbs and cant find anything wrong with it. I have recently had an electrician take a look and he was baffled too. I never know when I am going to get stranded somewhere in the dark, sometimes it is the fuse but always the two headlights together. Can anyone help me?

 

This is just a guess, but could the headlight switch be shorting out internally causing the fuse to blow and lights not to work? You might find a new switch in a local junkyard to try out the theory. It can't be any worse than worrying about it or paying someone to replaced your bulbs and fuse every coupla' months, could it?
Again, I have not personally experienced this phenomenon, so this is ONLY a guess.
