My radio won't go off when my car not running dome light won't come on when I opened the door but about 5 to 10min it goes out

As for the dome light, on your steering column, either your blinker switch or yeah, I would say your blinker switch, there should be a little dial that just turns left and right, it might also be where you turn on your headlights, in fact that's where I would actually start LOL sorry just dawned on me what we were talking about, where you turn on your headlights there should be a little knob that's attached to it that just twist to the left and to the right or up and down that is or should be setting your dome light timer. I'm not sure about your radio.

Alarm won't work the roof door do not light on accord 1994

Check the dome light override switch lockated on the dome light itself, then check the fuse for "CTSY Lights" and finally, check the ground attachment by removing the lens cover of the dome (roof) light, an removing the plastic housing of the dome light by either removing a screw, or simply prying on the sides of the plastic housing, you should see a wire screwed into the roof metal.

The interior lights will not come on when door opens, the visor lamps will NOT light no matter what, radio lights work normally the turn signal lamps blink fast, but all bulbs light

For the turn signal flashing fast - MAKE SURE you have all bulbs flashing that are SUPPOSED to be flashing. The front side marker lamps are part of this equation.

As for the interior (dome and visor) lamps, there is a fuse labeled "CTSY LAMP" in the fuse block. The lamps themselves are controlled by the body control module (BCM). The CTSY LAMP fuse only provides input power to the BCM. I would start with a scan of the BCM to see if it can shed any light (No pun intended) on your problem.

Fuse labled ctsy what does it service

Hello swatem1: My name is Roger and I will help. You did not specify a specific year car you were looking for. This is for a 1988 thru 1991. They do change things from time to time. The ctsy fuse carries power for the inside lights,power antenna,automatic safety belts (1991) and the warning and alarms (1991). Should you need more specific to d different year please just ask. Please rate the answer. This way I know it was helpful. Thank You for using Fix Ya. Roger
