Vanity light inop/glove light inop. - 1991 Honda Accord

My thought would be room lamp, 15 amp. Interior fuse box.

Check the fuse marked "courtesy"

Do a draw test on the battery and then start pulling fuses while you watch the amp meter.. Also check for lights left on like glove box light, vanity mirror lights left on in sun visors, these are the most common source of draws.

Looking at a wiring diagram the dome light and rear reading lights operate through the body control module. Check the BCM 2 fuse, BCM 1 fuse and BCM cluster fuse they may all be in the circuit. These fuses are in the engine compartment fuse box.

Dome glove box trunk vanity map lights all out 2003 Saturn L300

a battery should not discharge overnight check for drains on battery. items like lights ,vanity mirror glove box. also have battery checked ,it may be bad .

Interior lights blink off and on ????? As in dome lamps, dash light's etc...??? An what the heck is this mean We were told to hinge the module?????? I have been an automotive technician over 30 yr's an never heard the term hinge the module. The interior lighting on your vehicle is controlled by the smart junction box , ford's BCM body control module . ( Electronic's ) Who checked the vehicle ? Dealer ?
Interior Lighting The interior lighting system consists of the following:

• Smart junction box (SJB)
• Interior/map lamp assembly
• Rail lamps (if equipped)
• Glove compartment lamp assembly
• Dimmer switch
• Illuminated vanity mirrors (if equipped)
• Rear cargo lamp
• Puddle lamps (if equipped)
• Door ajar switches
• Liftgate glass ajar switch

The interior lighting system consists of 2 subsystems:

• Courtesy lamps
• Demand lamps

The courtesy lamps are controlled by the SJB. The courtesy lamp subsystem consists of the ajar switches, the interior dome lamps, the puddle lamps, the roof rail lamps, the cargo lamp, and the overhead console lamps (if equipped). The SJB supplies voltage to the courtesy lamps when the SJB receives the required input.
The demand lamps subsystem consists of the glove compartment lamp, the dimmer switch, the cargo lamp, all map/reading lamps, the roof rail lamps, and the LH and RH vanity mirror lamps.
The SJB supplies power to the interior lighting system. The SJB sets DTCs if certain circuit failures exist with the interior lighting system.

1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.

1. NOTE: Make sure to use the latest scan tool release software. If the cause is not visually evident, connect the scan tool to the data link connector (DLC).

1. NOTE: The vehicle communication module (VCM) LED prove-out confirms power and ground from the DLC are provided to the VCM. If the scan tool does not communicate with the VCM:
   • Check the VCM connection to the vehicle.
   • Check the scan tool connection to the VCM.
   • Refer to Section 418-00 , No Power To The Scan Tool, to diagnose no communication with the scan tool.

1. If the scan tool does not communicate with the vehicle:
   • Verify the ignition key is in the ON position.
   • Verify the scan tool operation with a known good vehicle.
   • Refer to Section 418-00 to diagnose no response from the powertrain control module (PCM).

1. Carry out the network test.
   • If the scan tool responds with no communication for one or more modules, refer to Section 418-00 .
   • If the network test passes, retrieve and record the continuous memory DTCs.

1. Clear the continuous DTCs and carry out the self-test diagnostics for the SJB.

1. If the DTCs retrieved are related to the concern, go to the Smart Junction Box (SJB) Diagnostic Trouble Code (DTC) Chart or the Power Liftgate Module Diagnostic Trouble Code (DTC) Chart. For all other DTCs, refer to Section 419-10 .

1. If no DTCs related to the concern are retrieved, GO to Symptom Chart .

check the fuses.
what interior lamp , name one, there are like over 25.
doom, dash,park, idiot, blinker, vanity. glove, cig , etc.

The SJB supplies power to the interior lighting system. The SJB will set DTCs if certain circuit failures exist with the interior lighting system.
