I'll bet ya a sub at D'Angelo'* it'* the door handle switch.

If we search on this problem, we'll find the right fuse instead of whatever popped into my head as I was aiming to the bar at TGIF'* last night when I got your text.

It'* an obscure fuse with a name that doesn't sound like interior lighting as I recall.

The issue usually is the switch hooked to the door handle went bad and unhooking it will stop it from grounding the circuit and keeping the lights on. The drivers door handle is typically the one that has the issue since it is used the most.

I clicked ye ole search button and punched "interior lights" and the electrical section. Presto..

Here'* a general diagnosis thread that isn't worth much except showing that I answer the same most of the time to this one.

And here'* the thread with the fuse that disables the lights mentioned by it'* location.

What does the door handle switch look like? and the lights wont turn on when I lock my car anymore when I pull it? and my lights will work again, but they just wont work when i lock my car?

Raph..you can always count on me to have had the problem at some point. Although searching on me might return 30K posts..lol
