Is there a relay for the interior lights that operates when you open any door? when I open a door, fuse 8 blows..but with the door closed it works fine, even the overhead dome light. i think its in the relay ....if there is one.

Re: fuse 8 blows, dome lights
There is no relay, you have a short in the system, I have fixed dozens of dome light problems on the Taurus and it was seldom the same problem from car to car, check the door switch wires first, remove the switch and diconnect it, if the short goes away the wiring is shorted to the door switch. I am sorry but there is never easy solutions to this kind of problem.

Courtesy Lamps - central junction box. fuse # F1.21 that goes to interior lamp relay in the instrument cluster and F.24 this fuse powers battery saver relay .
The interior light system consists of the following:
front map lamp assembly
front door courtesy lamp
generic electronic module (GEM)
glove box lamp assembly
central security module
interior lamp switch
interior lamp relay
illuminated vanity mirrors (Navigator only)
reading lamp assembly
rear courtesy lamp
running board lamp
underhood lamp assembly
The generic electronic module (GEM) illuminates the interior lamps when an unlock signal is received from the remote anti-theft personality central security module. The illuminated entry feature will be canceled when any of the following conditions are met:
25 seconds have elapsed since the illuminated entry feature was activated and the interior lamp control is not activated (door ajar or courtesy lamp switch on).
The GEM receives a request from the central security module (remote transmitter lock button pressed) and the interior lamp control is not activated.
The ignition is in the RUN or START position and the interior lamp control is not activated.
The GEM will illuminate the interior lamps when any door is open or ajar. The interior lamps are; the dome lamp, the rear cargo lamp, the door courtesy lamp and the side rail lamps. The courtesy lamps will shut off when the doors are closed and the illuminated entry feature is not active or when the vehicle speed is greater than 5 mph (8 km/h). The interior lamps will not be reactivated until the vehicle speed is less than 3 mph (5 km/h) and a new door open warning lamp switch is received.
The GEM controls the interior lamps illuminated entry function by activating the interior lamp relay.
You have an electronic control module and relays involved in the operation of these lights also !
great post and first to do fuse checks, for phantom drains.
G16 or J18 engine????
very good work. did you look at car in 100% dark,. all doors open , hood and trunk? called dark current checks.
and you are correct ,most fuses have many loads. some are 20 or more. (now windows ,usually)
DOME (im logged in to alldata.com so can you.....
Dome is doom, LOL called fuse #8 by suzuki.
a RED feed wire..... then white....
TCM, interior lights,trunk light,Radio, keyless,Clock and ECM
a real FSM make this far more easy, especially old cars.
and DC amp clamp meter 100x more easy.
alldata.com has the full set if schematics.
Time delay relay is the relay that allows the interior dome light to remain on for a brief time when you enter or leave the car.Usually the lights will remain on for a few minutes and then dim down and finally off.
It sounds like the daytime running lights were put on that circuit and the relay removed to keep them on constantly.
This sounds like a time and material repair that a shop will have to do. Tracing the wiring installed by the previous owner may be required to find out what was done.
Does your interior dome light work,if it doesnt take the dome lamp assembly out and disconnect the wire harness from there, reinstall the fuse and recheck lights,The possible short is coming from 2 likely areas the dome light or the dimmer light,what you do to the dome light to trouble shoot the short you will also perform on the dimmmer switch
all the lights above the dash do not work ?????? DOME light's ??? No light's come on when you open the door or any door ? Wouldn't think all the door ajar switches bad at one time .
The interior lamps consists of two groups, lamps that can not be dimmed and lamps that can be dimmed. This first group consists of lamps that may not be dimmed. This Includes those lamps that may be manually turned on by placing the interior lamp switch to the DOME position, or by opening a door or a compartment:
• Auxiliary dome lamp (SEO, RPO 6C7)
• Dome lamp
• instrument panel (I/P) compartment lamp
• Inside rear view mirror lamps
• I/P courtesy lamps
• Reading lamps
• Rear compartment courtesy lamp
• Sunshade vanity mirror lamps
Battery positive voltage is applied at all times to the DIC/RKE fuse and to the switched side of the BATT RUNDOWN PROTECTION relay in the right I/P junction block. The DIC/RKE fuse supplies battery positive voltage to the coil side of the BATT RUNDOWN PROTECTION relay. When the ignition is turned to the ON position, the body control module (BCM) provides a ground to the Inadvertent relay control circuit. This energizes the BATT RUNDOWN PROTECTION relay and applies battery positive voltage to I/P BRP fuse and to the TRK/ROOF/BRP fuse. Battery positive voltage is applied from the I/P BRP fuse to the I/P courtesy lamps, I/P compartment lamp and to the I/P compartment feed circuit to the BCM. Battery positive voltage is also applied from the TRK/ROOF/BRP fuse to the:
If the BCM receives a door lock or unlock input signal, the BCM will activate the BATT RUNDOWN PROTECTION relay, which provides battery positive voltage to all interior courtesy lamps. When any door is opened, the door jam switch contacts close and the BCM receives a door-open input signal. The BCM then applies a ground to the theater dimming ground control circuit illuminating the courtesy and dome lamps.
After all the doors are closed, the courtesy lamps remain illuminated for approximately 40 seconds. The courtesy lamps will also turn on and remain illuminated for approximately 15 seconds after the ignition key is removed, prior to any door being opened.
When the headlamp switch is placed in the DOME position, the BCM receives a ground signal. The BCM then applies a ground to the theater dimming ground control circuit. This illuminates the dome and roof rail lamps.
The courtesy lamps will normally turn off using the theater dimming feature. The BCM provides a pulse width modulated ground to all courtesy/reading, dome, and inside rear view mirror lamps for the theater dimming feature. The BCM will immediately turn off the courtesy lamps if a door lock command is received with all the doors closed, or if the ignition switch is turned to either the ON or RUN position.
The BCM activates the interior lighting output 15 seconds after receiving the class 2 message "Airbags Deployed" from the sensing and diagnostic module (SDM). The interior lamps remain activated for 25 minutes.
The door ajar switch is part of the lock actuator inside the door !
Do you has an after market (non-factory) alarm system?
Locate and check the alarm module's inline fuse(s) and relay(s)
Open covers and check every dome light bulbs.
Clean the door and rear hatch electrical contacts.
Some interior lighting system has a "slow dim" or "theater" lighting module.
Check for loose connection at the module.
the short is either in the door switches or the dome / interior light fixtures them selves. I would check your door switches 1 at a time does the fuse blow immediatly upon install or when you open a door.
Did you check the switch next to the interior light on the roof? Honda's have a switch position that turns off the dome light completely, so it won't work when the doors are opened or not shut tightly. There are 3 positions, dome light on all the time, dome light on only when door is opened, or ajar, and dome light off. I must say, I love Honda's, but I find this switch annoying!
