Hi, i have a 2007 vauxhall vectra. Change side light as dash said not working. Still not working after changing it? Any ideas please. Thx Naomi :-)
Bulbs not working can be for a number of reasons. It could be a bulb, a fuse or a wiring problem. Checking the fuse is easy to do.
Just changing the bulb may not resolve the problem (as in your case). Take the bulb that is not working and place it in another working bulb holder to see if the "so called" blown bulb actually is okay. If it doesn't light up then throw it away, don't put it down as you will get it mixed up with working ones (been there, done that). Take the "known to be working" bulb you removed from the working bulb holder and try that in the "blown bulb" holder. If that doesn't work replace it in the original working bulb holder and see if it still works. If it does then the "blown bulb" holder is the place to start looking. Clean up the contacts on this holder and try a bulb again. Still no luck, check the wiring at the back of the holder for broken connections. Most cars are now wired to light clusters that hold indicators, brake, side, reverse and fog lights. These are all on a circuit board (you will see what looks like silver strips from each bulb holder running to a connector that the wiring loom plugs into). If you have a meter, check to see if you have power to the faulty holder. Sometimes just wiggling the bulb or connector plug will make the bulb work, in which case it is a connection issue. If you can, try swapping over the left and right light clusters (just remove and plug in as they won't fit the car the wrong way round). If the "faulty" cluster works in the "working" side and the "working" has the same original problem in the "faulty" side, then it is the light cluster that has the problem and not the wiring from the connector back into the cars wiring loom.....big relief.
I always find electrical issues frustrating, so be methodical and eliminate any possible problem one at a time. Don't do lots of work and then check because if you can identify the single cause, should it reappear (and it most probably will in my experience) that is the first place to check again.
Good luck and hopefully that eliminates the need to call an expensive repairman.
