Windows cannot go up or down

The fuses and relays cover all the windows, so the likely culprit is the door switch module.

After I verify both driver window control switch and the passenger wdo control switches don't cause the window to operate, I turn off engine and go on ACC Mode and listen for a relay clicking in the door or the BCM while you operate the switch. If you hear a click, then it's a bad wdo motor.

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).

The Trainer 24 Power Window Troubleshooting

Are all windows not working ? Two separate circuit breakers left & right . Both in rear fuse box . Fuse Block - Rear Beneath the left rear seat
Check for broken wires inside the rubber boot from body to doors.
Do you know about electronic control modules ?
The power window system consists of the following components:
?€¢
Driver door module (DDM)

?€¢
Passenger door module (PDM)

?€¢
Body control module (BCM)

?€¢
LR power window switch

?€¢
RR power window switch

?€¢
Window up and window down relays in each of the rear passenger window switches

?€¢
Window lockout switch

?€¢
Reversible power window motors in each of the doors (circuit breaker protected)

?€¢
LT DOOR CB 25A (System power for left rear window)

?€¢
RT DOOR CB 25A (System power for right rear window)

The power window system will operate anytime the retained accessory power (RAP) system is active or when the ignition switch is in the ACCY or ON position.
The DDM contains 4 power window switches which are integral components. Closing any of the normally open, rocker type switches provides the DDM with a request for power window operation. The switches for the 2 front windows have 3 positions Up, Down and Express Down, while the switches for the rear windows have only 2 positions, Up and Down. Each of these switches and their positions is a direct input into the DDM. Upon receiving a request for power window operation, the DDM, transmits a class 2 message indicating the switch and it's changed position.
The PDM contains a single power window switch that is an integral component. Closing of this normally open, rocker switch provides the PDM with a request for the front passenger power window operation. The switch for the front passenger window has 2 positions Up and Down. Each of these switch positions is a direct input to the PDM.
The 2 rear passenger doors have there own switches. Each of the switches contain a power window up and down relay. A switch activation alone can control the up and down functions of the rear windows. However the BCM, upon receiving a class 2 message from the DDM, can control the set of relays which will activate the rear window motors.

Check

Sorry but there is no relay switch ! Go to www.bbbind.com free wiring diagrams .Check it out ! Your regulator is probably bad ! Is there B+ voltage at the switch , at the motor ?
Left Front Window Switch Operation
Place the ignition switch in the RUN position in order to supply battery voltage to the left front door lock and side window switch through the POWER WINDOW circuit breaker and the CKT 1001 (DK GRN). Press the left front window UP switch in order to supply battery voltage to the left front side window regulator motor through CKT 164 (DK BLU). The window motor is grounded through CKT 165 (BRN) and the window switch DOWN contact.
The regulator motor runs to drive the window to the UP position. Press the DOWN window switch in order to provide battery voltage to the window regulator motor in the opposite direction through CKT 165 (BRN). The window regulator motor is grounded through the CKT 164 (DK BLU) and the window switch UP contact. The motor runs in order to drive the window down.

You can't put up the front passenger window with it's own switch ? Did you check the POWER WINDOW RELAY in the instrument panel fuse / relay box ? An you checked POWER fuse 30amp same fuse box ? All window switches have direct power from power window relay !

at all stations?
all fuses, in both boxes. (did you read the operators guide to find them,
some cars have a circuit break (thermal) for windows,
and is located in the fuse box.
all this info is at alldata.com
ill look. ill respond , as you are a pro DIY person, can read schematics. if not , its just a guessing game.
IT IS a FUSE, not a breaker. but each motor in door has CB.
UNDER HOOD 40am Fuse #13
then fuse 23 underdash and fuse 8 same.
then the relay.same place.
and the relay is controlled by, master station (drivers)
the driver location doesnt need the relay to work.
the relay feeds power to all other window controls
so the master station is unique.
log in to alldata.com and see the pages on power windows.
here are some tid bits.
battery pull warning

Resetting the power window control unit is required after performing the following procedures: Disconnecting the battery, Removing the No. 6 (7.5 A) and/or the No. 23 (20 A) fuses from the under-dash fuse/relay box or disconnecting the driver's door wire harness.
and
window relearn/reset.
Control Unit Reset

1. Turn the ignition switch ON (II).
2. Move the driver's window all the way down by holding the driver's switch firmly down; when the window reaches the bottom, hold the driver's window switch firmly down for 2 seconds.
3. Move the driver's window all the way up by holding the driver's switch firmly up; when the window reaches the top, hold the driver's window switch firmly up for 2 seconds.
4. If the window does not work in AUTO, turn the ignition switch OFF and repeat the procedure.
5. Check the window and power door lock operations

Cannot be window switches. 4 of them do not all go bad at same time. but they all have in common the power that feeds them and is obviously not getting there. Using schematic trace voltage to the switches. Gtranted you changed the relay but is power getting to the relay for it to switch?

use owners manual to find location of window motor relays or look foward to changing all motors and regulators

Try the relay under the steering wheel, behind the panel that is held by two bults hidden under removable covers. Also two screws at bottom of panel. power goes to the fuse before the relay.
