For most vehicles it is on the inside front of the door, where it is pressed down if the door is shut.
check the drivers door jam area you should see a little tab sticking out it pushes in and out when opening and closing the door that triggers the light
The dome light switch on the dash is on.
Put the dome light switch on door located on the headliner to the side of the light
The switches for the dome light on each door of a 2004 Olds Alero are at the front of the door. They are on the door frame where the door meets the frame when it is closed. If the dome light is staying on, try checking the dome light control by the headlight switch, also. It may have gotten bumped when entering the vehicle.
a relay does not control both dome light and the radio.
the dome light fuse...any other questions
is the switch on the dome light set to doors! if so, one of the door switches are stuck. spray all door switches with a good lubricating spray. and push on buttons with hand to free them up. if not that, then one of the door switches are bad. or the dome light bulb is burnt out.
By pass the door mode. The Dome light should have a 3 way switch OFF - Door open on - Constant on Move the switch to the off mode, and light should not come on when door is opened.
The dome light switch has 3 positions. Off-On-On when the door is opened. Put it in the proper position.
Usually under the Steering wheel there are fuses for the Radio and Dome Light. Check and make sure they aren't blown. The Dome light fuse controls Time/Clock, and sometimes stuff like Door Lock controls, Keyless Entry Systems, Dash Cluster Lights, and maybe even headlight controls.For the Radio there will be Radio No.1 and No.2 fuses check both of these.
A door switch may be broken or out of adjustment or the dome light switch on the dash is turned on.
