SOURCE: 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.

Do you have access to an amp clamp to check amps going to the glow plugs. Remove the oil temp sender which is on the back of the hi psi oil pump reservior 2 wires. This will make the relay run longer. Then hook clamp over the 2 brown wires on glowplug relay should have about 175 amps if its working right. I have also seen the fuel heater inside the fuel filter housing go bad as well. Might check all the fuses as well incase the fuel heater fuse is blown.

SOURCE: 96 taurus wagon interior lights and power windows

just a guess but Id look for a bad chasis ground. I say this cuz the interior light switch for the door is a normally- open - grounding. The test for this theory would be to run a jumper wire from the neg batt terminal to the body, or from the eng to the body/chasis.

Lube your door latches. One of the door ajar switches are sticking . Use wd40 or some othe spray lube . Spray into the latch and open and close doors several time.

SOURCE: Interior lights will not come on when opening door

You need to check ALL the door switches that make the light come on....chances are ONE of them is defective. When you open ANY of those doors, all you are really doing is connecting a ground to that light, but if one of them is not working, it doesn't matter how many doors you have open, it won't ever come on...
Depending on how difficult it is to disassemble each door post switch, it might be possible to bypass all the switches and then put each one back into the system individually until you find the culprit. You also need to run a long jumper wire to the negative side of the bulb and make sure it is a known good bulb and a good socket FIRST!
Hope that helps!

The 97 Bonneville. That has. The twilight sentinel feature. The dash. Or cluster does not work none of the int light works and the fog lamp all fuses are goods


Twilight feature is used by the BCM to turn on the headlights when light levels diminish. Dash, cluster lighting is controlled by a rheostat near the headlight switch. The rheostat is rolled up for brighter lights. If this does not work the interior module may have burned out or the rheostat may be bad. If interior lights come on when rheostat is rolled fully up it most likely is OK. Interior lighting module is located above the headlight switch beside the cluster on the left side.

Where is the location to replace overhead lights fuse in 2003 oldsmobile aurora


Rear fuse box. INT LP 10 amp . there is also INT LP relay in the same rear fuse box .
Fuse Block - Rear
Under the rear seat, on the left side of the floor pan
The INT LP fuse in the fuse block - rear supplies battery positive voltage to the normally open switch contacts of the INT LP relay. The INT LP fuse also supplies battery positive voltage to the INT LP relay control circuit. The fuse block - rear also supplies battery positive voltage to the relay control circuit for the front courtesy lamp. The door modules communicate on a simple bus interface (SBI). When you open any door, the switch contacts of the door open switch close. When a door open signal circuit is grounded, that door module sends a message to the drivers door module (DDM) in order to indicate that a door is open. The DDM sends a class 2 message to the rear integration module (RIM) in order to indicate which door is open. The RIM activates the INT LP relay in order to provide battery positive voltage to the interior courtesy lamps. When any front door is opened, the RIM will energize the FRT CTSY lamp relay grounding the I/Pcourtsey lamps at G302. Depending on which doors are opened, front or rear, the proper interior courtesy lamps illuminate. The RIM provides a pulse width modulated ground to all interior courtesy lamps for the interior lights theater dimming feature. Some of the courtesy lamps are also used as reading lamps, each reading lamp may be manually turned on or off using it's own respective switch

Where is the interior light relay on 2001 ford windstar


Your interior lights are controlled by the GEM - generic electronic module !
Battery Saver The battery saver relay is controlled by the generic electronic module (GEM) and is located in the fuse junction panel. The battery saver relay is designed to supply B+ voltage to the following:
  • dome and map lamp switches
  • visor lamps
  • glove box lamp switch
  • interior lamp switch
  • interior courtesy lamp relay
  • delayed accessory relay
The function of the battery saver relay is to prevent excessive battery drain by interior lighting circuits. The GEM supplies a ground signal to the battery saver relay anytime one of the wake-up inputs of the GEM is activated to operate the battery saver relay. A wake-up command is sent when:
  • any door becomes ajar or is opened or closed.
  • the ignition key is inserted or removed.
  • the ignition switch is turned from OFF to RUN.
  • the ignition switch is turned from OFF to ACC.
  • a wake-up request is received from the remote anti-theft personality (RAP) module (if equipped).
  • The GEM will maintain the ground input with ignition in RUN or for 40 minutes from the last input activation with ignition in the OFF position. After 40 minutes the ground signal is discontinued.
This de-engergizes the battery saver relay preventing B+ voltage supply to the controlled switches and circuits.
  • Courtesy Lamp On Continuously
  • Short to power.
  • Damaged switch.
  • Generic electronic module.
  • GO to Pinpoint Test AF .
PINPOINT TEST AF: COURTESY LAMPS ON CONTINUOUSLY AF1 PRELIMINARY CHECKS
  • Check connections for clean tight fit.
  • Check for loose or damaged wires.
Do components and wiring check OK? Yes No GO to AF2 . SERVICE or REPLACE as required. GO to AF2 . AF2 CHECK CIRCUIT 53 (BK/LB)
  • Remove interior lamp relay.
  • Measure voltage at interior lamp relay connector Pin 87, Circuit 53 (BK/LB).
Is voltage greater than 0 volts? Yes No SERVICE Circuit 53 (BK/LB) for short to B+. RESTORE vehicle. RETEST system. GO to AF3 . AF3 CHECK CIRCUIT 434 (LB/BK)
  • Measure resistance between interior lamp relay connector Pin 85, Circuit 434 (LB/BK) and ground.
Is resistance 5 ohms or less? Yes No SERVICE Circuit 434 (LB/BK) for short to ground. RESTORE vehicle. RETEST system. REPLACE interior lamp relay. RESTORE vehicle. RETEST system. Interior lamp relay is located in the Instrument panel fuse box .

Need image of a 2001 f250 fuse box diagram


Which fuse box? there are three: The Battery Junction Block (BJB), the Central Junction Block (CJB) and the Bi-Fuel Relay Module.

Please review this article: Where's The Fuse?

Also, the information that you are probably trying to find is covered in the Owner's Manual for your vehicle. (Look under the heading of "Roadside Emergencies")
If you don't have an owner"s manual, you can download a FREE .pdf version at the Ford web site. I have provided a direct link below. You can save this file to your computer for future reference.

The interior lights in my 2000 Ford F250 will not turn off. How can I get the lights to turn off?


Just to get the interior lights off to save your battery, you could pull the fuse. Refer to the service manual to determine the proper fuse.

To fix the problem, i would suspect one of the door switches is faulty.

Interior lights dont work


Will it come on when the passenger door is opened? or at least when you turn the interior light on with the switch on the dash? If not it could be a fuse. If it does then the switch button in the door or door jam is probably the culprit. If it does not.. Then I would suspect a fuse... A broken wire, Or the dome light needs to be replaced.. Meaning the housing itself.. A test light will tell you if you have current to the light or not with the door open... Or find where the wire meets the assembly and test or pierce the wire and see if it has current at the wire... If it has current before the assy but not where the bulbs hot wire comes in then it's the assy. If it has no current before the assemly then check the fuse... then pull the fuse and test the contacts... If none if those contacts light up the test light Then you don't have power to the fuse for that light and your problem is behind the fuse panel or a wire going to the fuse panel... Start at fuse.... If it's good and has power to both sides. Then go to the light assy itself. If it does come on when the passenger door is opened then go to the button in the door jam... If it doesn't check the wires on the back side of the assy. It's a process of elimination... but do it in this order to find it quicker

Interior light and diagnostic plug doesn't work


The data link gets it's power from fuse no. 3(20 amp) in the interior fuse panel,which also is the power for cig. lighter. This fuse gets it's power from fuse no. 103 in the battery junction box (50 amp).

For the interior lights the door adjar switches in the door send a signal to the GEM module.It then grounds the coil side of the interior lamp relay. The switch on the dash that you turn on manually also grounds the coil side of the interior lamp relay so that would mean that everyrhing after the GEM is ok.Are the lights not turning on from any door including the deck lid? If not then problem would have to be in the GEM module.
