2003 Sedan-- G35 Dome lights and vanity lights will not come on when doors open or when the 'on' button is pushed. Is there a universal on/off switch i'm not seeing?

 

if the vanity mirror lights are out to it may be a fuse

 

fuses are fine

 

Bulbs out? Might as well upgrade to some LEDS I just put some in the other day love the way it looks.

 

If the fuses are fine then there might be a problem with your BCM. Also make sure you check your bulbs.

If the bulbs are fine then the only thing that you can do is to take your car to the dealership. Or you can take the dome/maplight wires and solder it together with with the step light wire so that it'll be drawing power from there instead. Had a similar problem, but with my step lights.

 

on top of the lights (the top on the roof) there should be a switch next to the light that you switch to on/door or off maybe you just have to switch it to the door so when you open it the lights should automatically go on

 

RTFM. I did (for the same reason). Flick the switch in the centre of the reading lights to the left. The double light will come on, but it will go off under the proper conditions. And come on when the door is opened. The manual also addresses how to make the rear seat overhead lights operate.

 

BCM is my thought LOWKEY ur gonna be dark for some days to come cause that thing is EXPENSIVE! I advise you get it new because junk yards dont do returns on electrical parts and this problem is actually common! Ran me around $500

 

Well it depends on how cheap they're willing to sell it at a junkyard. For the most part the bcm shouldn't die on you or screw up unless you did something to mess it up. I did something to mess mine up -____-.. luckily it was just the step lights and I could kinda fix it.

Maybe the dealership can fix it? If not if you can get a bcm for like $150 or something at a junkyard.. DO IT!
