You will have to do some basic electrical troubleshooting to see if the bulb is bad or it's a loose connection. I recall it being an LED, but not sure. Sometimes if work has been done on the door, window regulator grease, window thingie fix, etc. a wire may have come loose.
The way to go is to pull the door panel and check it out. Remember that once you get the 7 screws loose holding the door panel on, the chrome strip DOES NOT come off with the door panel, it stays with the door!
I mention it, since my first time I bend the chrome strip, trying to rip it off with the door panel, cost me an additional $65 for a new one. Learn from my mistake!!
