Accessory delay relay

Bad relay more then likely .
Power Window Operation
The power window system operates under the control of the accessory delay relay. The instrument cluster module (ICM) grounds the relay coil to provide power to the power window system & the radio .

Symptom Chart Condition Possible Sources Action

• All power windows are inoperative

• Fuse(s).
• Circuitry.
• Instrument cluster module (ICM).
• Accessory delay relay.
• Driver window control switch.

• Go To Pinpoint Test A .

The first step to diagnose this problem would be to hook up a factory scan tool an check for DTC'S - diagnostic trouble code's in the ICM . If no codes do pin point test A

What's FX4 ? How many door's ? Do the other door switches have battery power ? Can you test this with a volt meter ?

Principles of Operation
The left front window switch may be used to raise or lower all windows, or each individual side window may be controlled by the control switch located on each door panel.
The instrument control module (ICM) controls power to the power window system by activating or deactivating the delayed accessory relay.
The one-touch down feature will completely lower the driver side window when the master control is fully depressed, then released. The one-touch down feature is integrated into the LF window control switch.
There are 2 modes of LF window down operation: manual mode and auto mode. The manual mode is selected by pressing the LF window control switch to the 1st (DOWN) position. In manual mode, the window will move downward only while the switch is depressed. When the LF window control switch is pressed to the 2nd DOWN position, it enters auto mode and the window will open completely with a momentary press of the switch.
When the one-touch down feature has been activated, it will stay on until one of the following conditions is met:

• The LF window control switch is pushed to the UP position.
• The LF window control switch is released (OFF position) and then moved to the DOWN position (1st detent) or ONE-TOUCH DOWN (OTD) position (2nd detent).
• 7 seconds have elapsed since OTD was initiated.

Window operation is enabled whenever the delayed accessory is active and the LF window control switch is pressed to the UP or DOWN position. The switch provides delayed accessory power to one side of the motor and ground to the other side. The one-touch down feature is not active when the LF window control switch is in the UP position.
Passenger windows may be raised or lowered using the LF window control switch or the appropriate passenger window control switch. Passenger window control switches receive power when the delayed accessory relay is active and the LF remote lock-out switch is in the UNLOCK position. When in the LOCK-OUT position, the passenger windows are deactivated.
The delayed accessory relay provides power for the operation of the power windows and the power roof opening panel. The delayed accessory relay is active whenever the ignition switch is in the RUN or the ACC position, or when the ignition switch is changed from RUN or ACC to the OFF/LOCK position and the LF and RF doors are closed.
The ICM will deactivate the delayed accessory feature when:

• The LF door is ajar and the ignition switch is in the OFF/LOCK or KEY-OUT position.
• The RF door is ajar and the ignition switch is in the OFF/LOCK or KEY-OUT position.
• 10 minutes have elapsed since the ignition switch was changed from ACC or RUN to the OFF/LOCK position.
• Symptom Chart Condition Possible Sources Action
  • All power windows are inoperative
  • Fuse(s).
  • Circuitry.
  • Instrument cluster module (ICM).
  • Accessory delay relay.
  • Driver window control switch.
  • Go To Pinpoint Test A .

All the other windows work ? Not a fuse , one fuse powers all the windows . Test for B+ voltage at the switch an the window regulator would be the proper diagnostic procedure . Do you own a volt meter ? know how to read a wiring diagram ? how to do basic automotive electrical testing . The Faint click you hear is probably a relay , which means the GEM - genaric electronic modual is energizing the window relay . The windows are computer controlled .

The GEM will activate the OTD Relay until one of the following conditions is met:

• The LF regulator control switch is pushed to the UP position.
• The LF regulator control switch is released (OFF position) and then moved to the down position (first detent) or one touch down (OTD) position (second detent).
• Seven seconds have elapsed since the OTD was initiated.
• A window regulator electric drive stall condition is detected on the one touch down sense line inputs.

The UP window operation is not controlled by the GEM. The feature is activated when the delayed accessory is active and the LF window regulator control switch is pressed to the UP position. The switch provides delayed accessory power to one side of the motor and ground to the other side through the one touch down relay. The one touch down relay is not active when the LF regulator control switch is in the UP position.
Passenger windows may be raised or lowered using the LF master control switches or the appropriate passenger window switch. Passenger window switches receive power when the delayed accessory relay is active and the LF remote lock-out switch is in the UNLOCK position. When in the LOCK-OUT position, the passenger windows are deactivated.
The GEM controls manual down and auto down window movement with the down window relay. The relay is activated by applying ground directly to one side of the down window relay coil, and deactivated by removing the ground signal.
The delayed accessory relay provides power for the operation of the power windows and the power moon roof. The delayed accessory feature is active when the ignition switch is in the RUN or the ACC position, or when the ignition switch is changed from RUN or ACC to the OFF/LOCK position and the LF and RF doors are closed.
The GEM will deactivate the delayed accessory feature when:

• the LF door is ajar and the ignition switch is in the OFF/LOCK or KEY-OUT position.
• the RF door is ajar and the ignition switch is in the OFF/LOCK or KEY-OUT position.
• 10 minutes have elapsed since the ignition switch was changed from ACC or RUN to the OFF/LOCK position.

Feature inputs:

• LF door open warning switch (open circuit with door closed, grounded with door ajar).
• RF door open warning switch (open circuit with door closed, grounded with door ajar).
• Ignition switch RUN position (battery potential on both the RUN and RUN/ACC inputs).
• Ignition switch ACC position (battery potential on the RUN/ACC input).
• Ignition switch OFF/LOCK position (absence of battery potential on the RUN, RUN/ACC, and START inputs).

Left Front Power Window Switch
The battery voltage is applied from the WINDOWS circuit breaker through CKT 42 (RED) to the accessory time delay relay. The accessory time delay relay supplies voltage through CKT 70 (PNK) to the left front power window switch under the following conditions:
?€¢
The ignition is in the RUN position.

?€¢
The retained accessory power (RAP) is active.

When an UP switch on the left front power window switch is operated, the battery voltage is applied to the power window motor. The power window motor is grounded through the DOWN contacts of the left front power window switch to G204. The motor runs in order to drive the power window up. When a DOWN switch in the left front power window switch is operated, the battery voltage is applied to the power window motor in the opposite direction. The power window motor is grounded through the UP contacts in the left front power window switch to G204. The motor runs in order to drive the power window down.
Accessory Time Delay Relay
On the left front of the passenger compartment, taped in the body harness

Check that there is power at the switches and check body control MODULE Check relays.

You need a wiring diagram to
learn the circuit your working on,
& find places to do your testing

According with the Explorer Owner Guide, I suggest...
1. Check for power on the Light Blue/Black (LB/BK) wire at the master window switch.
2. Check for a good ground to the master window switch on the Black (BK) wire. This wire provides the ground circuit for all of the window motors.

If both of these are good you probably have a bad master switch(drivers master switch).

The Light Blue/Black (LB/BK) wire gets its power supply from the accessory delay relay in the Central Junction Box (CJB) located under the instrument panel. The Generic Electronic Module (GEM) controls activation of the accessory delay relay. Fuse 2.17 is a 15 amp fuse in the CJB which supplies power to the relay. Fuse F1.6 is a 60 amp fuse in Battery Junction Box (BJB) which also supplies power to the accessory delay relay. G400(ground) is located at the driver side rear of the vehicle near the tail light assembly. This connection provides a ground for the master window switch (click image for zoom).




For additional details, i suggest try to look and obtain this 2002 Explorer Owner Guide 6th Printing (English).

Hope helps.

There is a black rubber flex boot between the body an the door ,power and ground wire's for the switch run through it . Opening an closing the door over time can cause the wires to break . Pulling the door inside trim panel to get to the switch wiring connector to test for B+ voltage an ground is the way to test electrical . Looking at a wiring diagram to see what wire is what should be done also. Do power lock's work ?

Window Operation
The window system operates under the control of the accessory delay relay. The smart junction box (SJB) will ground the coil side of the accessory delay relay when the ignition switch is in the ON position. When the accessory delay relay is active, power is supplied to each window control switch. The window control switches direct power and ground to the appropriate power window motor.

If the other windows work ,it's not a fuse problem . Broken wire's ,master switch !

the window relay is at fault

If you checked the fuses and they are fine, try this. With the key on and the window button down or up, open and close the door holding in the up or down position. If the window moves, there is a wire(s) are broken in the wire harness that goes from the door jam to the door. This is a common problem that we find with window and door operating problems. You may find 1 bad or broken wire, or 4-5 broken wires. Let us know if this help you find a repair, for this concern. Craig
