Daewoo tacuma 2 Lt I opened window then tryed to close it but did not close then tryed to open the rest of the windows nothing worked on all doors I tryed all door switches nothing. I tested for power on drivers door there is power. The switch makes a humming sound when I operate the drivers window.

BCM is bad or has no power.

Which window switch ? RT DOOR CB-circuit breaker , do you know what a circuit breaker is ? 25A (System power for right rear window)
LT DOOR CB 25A (System power for left 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.


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)

If you not sure about any of this I suggest you take your vehicle to a ASE certified repair shop .

then the Switch is Probably the Problem. But You Need to check the Wires AT the Door since they are bending all the time and they will Break Useally in the Harness between the Door and the Car body

pinched wire..

This sounds like the dirvers door master window control switch is bad, remove the switch, this is done by prying the front of it up and the whole unit comes out, make sure the connector to switch is in all the way, a matter of fact remove the connector from the switch and then plug it back in and see if the windows work, if not then replace that switch, what happens is the contacts in the switch wear out and burn and all switches run through the drivers switch, good day,

chance are you have a pinched wire in the door jam and when you shut the door its grounding out...

NO COST and fast PROCEDURE TO try to FIX IT:

1. Sit in vehicle, on seat next to problematic window
2. Ignition key is on
3. Door in question is opened (in case you closed it)
4. While door is open, press and hold power window button in desired window travel, keep button pressed !!
5. SLAM hard the door closed with one hand while other hand holds button as per #4.
6. Watch window operate as it should.

7. Repeat 3-6 if necessary, but usually the first try works!

open rear hatch and remove 3 screws down edge of lamp assembly gently pull assembly out and then you can remove globe sockets from lamp assembly to change globe

driver side lock and window switch... if its all one unit... i had a 95 cherokee laredo that did that... changed the switch and it fixed my problem...

Open the drivers door and look between the door and the door pillar(just above or below the hinge) you should see a black rubber ribbed covering. This has all the wires for the door locks,power windows, etc. in it. Good possibility that there is a wire or wires broken in there from all the door opening and closing of the door over the years.
