Default Interior light Issue

Basically, when I turn the **** there's only one spot in about the middle that the interior lights will actually work and they're very very dim. The headlights work fine, but I'm not sure what's wrong with the interior lights. Any idea?

Sounds like the rheostat in the head light switch is bad.

By pulling the dash forward a little to access the back of the headlight switch you will see the rheostat (little coil looking thing) when you turn the switch the arm move across the coil providing different resistence. Check that the arm is in contact with the coil thru the entire movement of the switch. You can pry the arm to make better contact but dont use much pressure or youll break the arm. Otherwise you might just want to buy a new switch.

I'd rather just replace it so I don't have to worry about it anymore. Where can I get one from?

Do you even know if the bulbs are good? ...or if power and/or ground are getting to them? That would be the place to start. Changing the headlight switch is the last resort.

Well I mean like I said I can turn it to the exact right spot and they'll come on but they're dim. I think that's because the only spot they come on is around the middle. So yes, the bulbs work.
