Interior lights not working


Sounds like you have a bad fuse, and or maybe a bad relay in your dash panels. Start by looking up the fuses that affect your sunroof, then work out to the other issues. On my Ford, there is a bad relay that affects my power windows, my radio, and my interior lights. Sometimes more than one fuse is related to a system, so check all the fuses before trying relays.

The interior lights on my father-in law's 2000 Safari are all inop (6 spots plus two dome lights) I can't find a fuse in the engine box for them. Is there another fuse box. The van has a dome overr


Does the van have remote keyless entry (RKE) system ?
Interior Lighting System Description
Vehicles with the optional remote keyless entry (RKE) system have interior lighting controlled by the body control module (BCM).
This vehicle uses a delayed interior lighting system.
The system functions as follows:
• The dome lamps will illuminate when any door is opened.
• The dome lamps will remain on for 20 seconds after the last door is closed.
• The delay is canceled and the dome lamps will go out when the ignition switch is turned to the ON position.
• The illuminated entry function will not operate when the dome lamp defeat switch is in the OFF position.
• The interior lighting system is protected from battery rundown by the retained accessory power (RAP) system. The RAP system functions by shutting down interior lights after 10 minutes (when ignition is OFF).

Interior Lights Circuit Description
When the interior lamps circuits are closed/enabled, the courtesy lamp relay is activated by the two following coil circuits:
• CKT 690 (GRY/BLK) which is the courtesy lamp enable output of the body control module (BCM) driving the coil side of the relay.
• CKT 1732 (ORN) which is the coil output side of the relay going to the potential grounding switches/sources.
When the courtesy lamp relay is enabled, CKT 156 (WHT) (courtesy lamp output) is enabled by the closed contact at the relay and then grounded by CKT 750 (BLK) at G110.
Some of these circuits can also be activated with the headlamp and panel dimmer switch. When this happens, the coil output side of the inadvertent power relay is grounded to the body control module (BCM) via CKT 1393 (DK BLU)
CKT 40 (ORN) from the courtesy fuse drives both input sides of the inadvertent power relay. When the contact is pulled closed, CKT 1732 (ORN) is supplied power, thus driving any lamps/circuits attached that circuit and providing ground.
The body control module (BCM) also monitors the following four door inputs:
• CKT 49 (DK BLU) -- LH door jamb switch input
• CKT 54 (ORN) -- RH door jamb switch input
• CKT 775 (PNK) -- Side door jamb switch input
• CKT 656 (YEL) -- Rear door jamb switch input/liftgate strut switch input (depending on option content)
When the doors are closed, the body control module (BCM) is in a floating state of 0-2 volts. When the doors are opened, the courtesy lamp relay is activated, sending power to the courtesy lamps.
The headlamp and panel dimmer switch also activates the following interior courtesy lamps when the switch is placed in the PARK or HEADLAMP ON positions:
• RF power window switch
• RH power door lock switch
• LH power window switch
• LH power door lock switch
• LH outside rearview mirror control switch
• Rear radio control head
The dome lamps can be disabled by closing the dome lamp defeat switch located on the headlamp and panel dimmer switch.

99 corolla passenger window wont roll up


Turn the ignition on but don't start the engine. Operate the windows from the master control switch. If none of the windows work, check the main fuse or breaker for the whole power window circuit. If only one of the windows is inoperative, go to Step 3.

  • 2 Check the main circuit relay using a test light. If voltage is coming out of the relay, there is an open or short at the wire feeding power to the other switches. If no voltage is coming out of the relay, use the test light to make sure voltage is reaching the relay. If voltage is reaching the relay, replace it. If there is no voltage reaching the relay, there is an open or short at the wire between the relay and the main fuse.
  • 3 Check the circuit fuse or breaker at the inoperative window. If the fuse or breaker is okay, go to the next step. If you can hear a humming sound as you press the switch but the window does not operate, either the motor is bad or its gearbox may have broken teeth. Go to Step 7.
  • 4 Turn the ignition on but don't start the engine. Using a multimeter, check the master control lockout switch for continuity. If there is no continuity, replace the lockout switch. With some vehicle models, problems at the lockout switch can cause both rear windows to fail.
  • 5 Try the switch at the inoperative window and check for continuity using a voltmeter. If there is no continuity, replace the switch.
  • 6 Check for voltage at the switch using a test light. If voltage is not reaching the switch, there is an open or short between the incoming wire and the fuse or breaker for that circuit power window.
  • 7 Take off the trim panel from the inoperative window. Check for voltage at the motor with a test light while pressing the switch. If there is no voltage, there is a short or open at the wire between the switch and the motor. If the circuit is equipped with a relay, test for voltage reaching and coming out the relay. Make sure the relay is working properly. If voltage is reaching the motor, go to the next step.
  • 8 Detach the window from the regulator and inspect the regulator mechanism by moving the window up and down by hand. Make sure nothing restrains the mechanism. Also, inspect the motor gearbox. Replace any parts as necessary.

    Fuse or what


    Your multifunction switch on the steering column controls your exterior lights. The GEM module controls the interior lights and other stuff. If bad, it would not blow fuses. WHich fuse blows?
    Your Ford dealer might be familiar with this issue, so call the service dept and ask them and get a quote. It may be wiring.
    reoprt back.

    • The high beams are inoperative
    • Circuitry.
    • Multifunction switch.
    • Go To Pinpoint Test C .


    --------------------------------------------------------------
    Principles of Operation
    Generic Electronic Module (GEM) The generic electronic module (GEM) receives inputs from the following:
    • door ajar switches
    • liftgate ajar switch (wagon)
    • liftgate glass switch (wagon)
    • headlamp switch
    • keyless entry keypad switches
    • the powertrain control module (PCM) (vehicle speed signal)
    • ignition switch
    • remote keyless entry transmitter
    The GEM uses these inputs to control the output to the battery saver relay and interior lamp relay. Both relays are integral to the central junction box (CJB) and cannot be accessed directly.
    Interior Lighting Systems The GEM grounds the battery saver relay and interior lamp relay coils when any door ajar switch or the headlamp switch is closed. The interior lamp relay then supplies power to the interior lamp circuit. Vehicle speed must be less than 15 kph (9 mph) for the GEM to ground the interior lamp relay. The interior lamps will remain illuminated for a period of up to 25 seconds after all doors are closed or until the ignition is switched from the OFF position, or the GEM receives a vehicle speed signal. Actuating the interior lights from the headlamp switch will operate at any time.
    Illuminated Entry Illuminated entry is activated when a keyless entry keypad switch provides ground on the GEM input or when the GEM receives an unlock signal from the remote keyless entry key fob. The GEM then provides ground to the battery saver and interior lamp relay coils. Illuminated entry is deactivated when the GEM receives a lock signal from the remote keyless entry key fob or if the GEM receives ground inputs from the keyless entry keypad switch lock code. Illuminated entry will also be deactivated when the GEM receives input voltage from the ignition switch.
    Battery Saver The battery saver is activated when the GEM is not receiving voltage input from the ignition switch (off position). The GEM will then provide ground to the battery saver relay coil for a maximum of 30 minutes depending on the state of the interior lamp switch inputs to the GEM. The energized battery saver relay switches voltage to the demand lamp circuit and the interior lamp relay coil. After time-out, the GEM removes ground to the battery saver relay disabling the demand lamp circuit.
    Puddle Lamps The puddle lamp relay operates reverse from the battery saver relay and the interior lamp relay. The puddle lamp relay coil receives voltage when the ignition switch is in the START or RUN position, which disables the circuit to the puddle lamps.
    Inspection and Verification
    1. Verify the customer concern by operating the system.
    1. Visually inspect for obvious signs of mechanical and electrical damage.
