So i just recently bought a fit, noticed the dome light was out of commission so i bought a new bulb, which i believe is a 3175 or 3022. replaced it and no luck, i then couldnt find the corresponding bulb fuse so i researched found out it may be #8 under the hood, that didnt work. i ended up switching every backup/light fuse the panel noted. No luck, yes my radio works all lighting including the trunk light, only thing not working is the dome light. any suggestions? thanks alot!

 

Try putting the bulb in the other way (reverse it's position/polarity). If it's a new bulb & no fuses are out it has to be the way the bulb is inserted (unless you got a more serious problem).

 

already tried that.....ouch!

 

since you have tried changing bulbs and fuses.. then that leave the cables or the security/alarm module. My car has the dome light cabling connected to the alarm module, so whnever i activated the alarm, the dome light would turn off immediately, and when i deactivate the alarm, the dome light will turn on immediately... try checking those

 

Are you referring to the factory alarm? I don't have a aftermarket alarm yet

 

nope, mine is aftermarket. I don't know whether the factory alarm is connected to the dome light or not. if not, than the cables it is... rerouting them won't be easy :P

 

Absolutely certain you don't have a bad "new" bulb?

 

I'll double check the two new bulbs I bought

 

I left my dome light on over night last night by accident after reading this, car started fine. The light was really hot, and I noticed how dirty the switch was, I should get led but am lazy.

Just click.

I got some of these in warm white and they are nice!

 

Instead of bulbs, use a multimeter. That way you can see if its dead or putting out 1.3 volts or something. That will give you clues and help you trace the problem back to its source.
