Looking for fuse location for the dome light in a 2002 320 ml

There's not likely a relay involved in a dome light circuit. Did this problem start after you changed the headlight switch? I would be looking for a wrong, shorted or swapped connection on the headlight switch (assuming that's where the dome light is turned on from).

Located in under hood fuse/relay center. Owners manual will give fuse locations and identification. Make sure dome light is not turned off by dimmer switch

If your anonymous vehicle still has all of the covers for fuse panels; look on the underside for a sticker that has the layout of what various fuses are for.

There is a short between the dome light and the door switches, this can be caused by something as simple as water damage. check all the wires and switches before you think it is the BCM.

your doomed

You shorted the interior lamps/or it is burned out. get the car manual and look for where the interior lamp fuse is located to check if its the fuse. IF all the courtesy lights on your doors are working, then your dome light bulb is burnt, check modifiedlife.com for the correct size bulb and order it from an online automotive lighting store for a fancy color or go to your local auto store for the standard bulbs they have available.

Hi Oscar. You've more than likely just blown a fuse. Look in your owners manual or fuse box cover for which fuse is for the dome light. It may be listed as curtesy lamps, interior lamps, map light or something along those lines. Good luck.

The manual states the fuse location # for interior lighting is 18 and the amp is15a. I am showing 18 is from far left bottom corner it is the second fuse going up.

does dome light come on when you open door? also look at the dome light switch and see if it has 3 positions

Fuse #26 should be a 10 amp unit that controls among other things, the interior lamps. Good Luck.
