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 .

Have a 2010 fj cruiser. The lights normally automatically shut off after a short period if you leave them on and leave the truck. Now they do not automatically shut off. Trying to figure out why.


Could be the battery saver relay. Swap it first, could be corrosion. If the other thing doesn't work, replace the relay. Could also be the body control module.

2000 FORD EXPLOYER: Power windows, dome lights not working which fuse number controls it?


Hello! In the Central Junction Box is fuse # 26 (10A) which powers the Battery Saver Relay...This relay, in-turn, controls the Power Windows, Electronic Shift Module, Glove compartment Light and Cargo light...If the fuse is good, suspect the relay...The Interior Lamp Relay and the Battery Saver Relay are the same...Either one could be at fault if the fuse proves to be good...See photo of relay below...Relay module Above right of gas pedal or lower left of AC/Heater/radio. It is an ugly place (Behind the center console)...

This is a documented fault if fuse #26 keeps blowing...The wiring on the rear of the relay module has a history of shorted and burnt connections on the socket of the Battery Saver Relay...Keep me posted...................Guru............Saailer

Battery saver relay is on and do not start


One it could be the battery but if your radio and stuff works then it is not the case, the clicking is your starter trying to turn over, so that could be it as well.

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.

  • Central junction box (CJB) fuse 226 (10A)
