Probable broken wire in the harness in the drivers door jamb.
There probably is only one cause for your interior lights to go on when you apply the brakes. There probably are brake light wires and interior wires that have warned together.
poor ventilation
probably the fuse is blown.
ford van 2013 E250 inide lights wont work
On your light switch there is a dimmer for the dash lights . if you turn it all the way to the left your interior lights should come on , turn it to the left and see if that works otherwise it might be a door switch .
Press dome override button 3 or 4 times till you here a beep to put headlights and interior lights back on auto
The dimmer switch when turned just past high, turns on the interior lights. There are switches in the door opening that turns the lights off when the door is closed. Either one of these can cause the lights to stay on if they fail.
A blown fuse or a damaged computer would cause the turn signals, interior lights, and door locks not to work in the Mazda 3. The fuses are located under the dash on the driver's side of the car.
i have the same problem my dash light turns on when i turn on the interior lights but when i turn on only ........the dash light they wont turn on but they work when the interior lights are on ........so they do work .,...is there a separate fuse ?
probably the heat on the drive ways or some cord in the car is just messed up.
