The passenger side and rear power windows don't work on 2000 Hyundai Sonata . They will work from drivers main control switch but not individually . Tried the lock out button on drivers side but nothing changed . Can lock out switch be replaced by itself or is it the whole control cluster ? Can it be something other than defective lock out switch ?

You say the driver window works? wouldn't be a main fuse or fusible link then -driver door locks and window wouldn't work either. Each door has a module inside (computer) . The driver door has a circuit breaker power feed an a fuse DDM fuse 10amp located in rear junction block circuit breaker is located in under hood maxi fuse block. The circuit breaker also feeds battery voltage to the other door modules too. PDM - passenger door module fuse 10amp located in the instrument panel fuse box and the RDM - rear door module RDM fuse 10amp located in the rear fuse box - under the back seat.

Each power window is connected to a permanent magnet motor. The motor raises or lowers the glass when the door module applies voltage to the motor. The direction the motor turns depends on the polarity of the supply voltage provided by the associated door module. The 2 front doors have their own separate modules. The rear seat contains a single module, which controls both of the rear power windows.
A serial digital communications link, called the simple bus interface, is used for communications between door modules and the driver's door power window switches. The use of serial digital communications allows the use of a single wire to convey switching information between the power door lock switch and the driver's door module (DDM). The serial communication is also used in order to transmit switching information from the DDM to the other 2 door modules.
The door modules apply battery voltage of the correct polarity to the respective window motor when any local, or power door lock switch, UP switch is operated, driving the window up. Battery voltage is applied to the respective window motor in the opposite polarity when any local, or power window switch, DOWN switch is operated, driving the window down.

Driver Door Module (DDM)
The driver's door module (DDM) directly controls the driver's door window motor and the express down window feature. The DDM sends window UP/DOWN messages received from the power door lock switch to the passenger door module (PDM) and to the rear door module (RDM) over the simple bus interface (SBI) line. The DDM also contains a class 2 data link which communicates with the other vehicle system modules. The left front power door locks and the outside power mirror are also controlled through the DDM.
Passenger Door Module (PDM)
The passenger door module (PDM) controls the passenger's door window motor. The PDM controls the passenger's door window directly from the right front power window switch or from instructions over the simple bus interface (SBI). The right front power door locks and the outside power mirror are also controlled through this module.
Rear Door Module (RDM)
The rear door module (RDM) controls both of the rear door window motors. The RDM controls the rear windows directly from the rear door window switches or from instructions over the simple bus interface (SBI).

Rear Passenger Power Window Operation
The rear passenger power window switches receive battery voltage through the window lockout control circuit if the window lockout function is disabled. Ground for the rear passenger power window motors is supplied through normally closed up and down contacts of both the rear passenger power window switches and the driver power window switch. When the either rear passenger power window switch is placed in the down position, the power window motor down control circuit is switched to 12 volts and is applied to the down side of the rear passenger power window motor. Since the other side of the rear passenger power motor is connected to ground through the normally closed up contacts of both the rear passenger and driver power window switches, the window travels down. By placing the rear passenger power window switch in the up position, the polarity of the power window motor is reversed and the window travels up.
The rear passenger power windows can also be controlled from the driver power window switch.

Did you try pushing the lock out switch on the drivers master switch ?

This fuse box diagram show a power outlet fuse in the inside fuse box. It also shows two fuses and a relay in the engine compartment fuse box.

The relay says for 3 power outlets
One of the fuses says for cigarette lighter
If all the fuses are good the outlet which does not work may have shorted and blew the fuse. Check outlet to see if it has power to it.

Before you replace anything, inspect the connector pins in both the driver's door switch and the passenger door switch. If you don't find any problem with these connector pins, replace the driver's door control switch.

first check to see if the lock out switch on the main power window switch is in the off position ! this will not allow those windows to work if off

Dear kaydynandtri, If you have the owner's manual find the power window relay. They are usually located in the fuse box. Check to see if there is another relay that matches that one and switch places with them. If the windows work or the accessory the relay came from does not the relay is bad. If this does not work I would replace the driver's door power window switch. I have also seen the wire break on older cars where it goes into front of driver's door.

I don't think so as they are working otherwise. So please check if the switches are faulty on the passenger side. this is because the motors work well with the main control and so the errors are on the individual switch control.
Similarly the driver side windows might have the line break ,check all the door hinges wires connection/harness for any break.

No won't be fuse. My guess is there is something faulty with the main controller. You could probably verify this by trying the switch on right rear passenger door. If it works there then the problem is at the main controller in the driver door. Could be a loose wire or the switch itself is broken.

sugest fuse ck 1st thing. Master bypasses individual controls. Power supply to rear windows is interupted. Ck for connevtor under front seats. Fuse may be labrled accessory or per win.

the driver side window switch is the problem.
