Just fixed mine today. The dom light fuse in the engine fuse compartment was blown. The radio/power locks will go out as well if this fuse blows.
a relay does not control both dome light and the radio.
need location of fuse for dome and radio.
I just had the same problem with my 02 Lancer. I found a bad fuse 10 amps, enclosed in a yellow plastic holder, cap, ...There are 2 10 amp fuse in this holder. The fuse is located under the hood, driver side fuse box. Hope this helps...Good luck
Non-factory installed radio? Installer might have used that circuit for memory on radio
remove the broken one and replace with a new and working bulbs.
You can replace the dome light bulb in a 2002 Chevy Cavalier by first prying the dome light cover off of the light. Then, remove the bulb and replace it by twisting the bulb from the socket.
In a 2004 Mitsubishi Lancer replacing the rear light bulb is relatively easy. First remove the plastic cover from the dome light. Unscrew the light bulb and insert the replacement.
The circuits have nothing in common. The dome light works whether or not the key is on, the radio only works with the key on.
Check fuses
Blown fuse.
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.
If the dome light will not shut off on a 2002 impala, check for a water leak in the roof that might interfere with the operation of the light. Also check for a bad connection with the ground wire or a short in the wires.
