most likely that would be a fuse
Its probably an electrical problem. Sounds like your BCM is the problem, they are pricey. You should bring it to a garage and have it looked at.
One or more fuses have blown.
Most likely your car battery is completley dead.
Loose wire?
the iso plug (black connectors) are wired up wrong, it has given the light circuit a constant live
Your battery is dead and you should probably take it to the repair shop and have them put it in for you. Couldn't it be the starter motor? The lights and radio come on, so there must be some juice and the battery.
Wrong kinda locks. Locks need to be upright.
there is something wrong with the wiring in you car or brain, you might as well take it to the mechanic.
My Jeep liberty fog lamp switch will not pull out unless the control for the headlights is turned on first. Could this be the reason?
Check the fuses
If the dome lights and the radio went out at the same time on a 1997 Isuzu Rodeo, it could be a fuse. There are two fuse boxes on that vehicle. One is on the passenger side in the engine compartment and one is located in the dash on the driver's side. The fuse for the radio is in the dash fuse box.
If it is the illuminating lights you are referring to in all three instances, it sounds like either a fuse to that circuit has blown or the bulbs themselves have burnt out and need replacing.
