Had this issue since i bought the car but didnt managed to figure it out.
On the right side of a car both power windows of both doors do not work. They do not work on both doors localy and dont work from a master controler in left drivers door.
Anybody has a clue where start to look for ?
Thanks.

Lasted long time till i started solving this problem.
I checked the RH heelboard fuses and found that the 15th fuse was missing.
Mounted the new one in and to my disappointment i have only a rear window that started working.
The front right window still doesn't work.
When i push the window button i hear a relay clicking, but window is dead.
Am i having a dead motor issue or is there anything I can check before searching for a spare motor?
If the clicking you hear is in the master switch then it might be that the relay contacts are dirty. I had this on my car.
the contacts would pass voltage but NOT current I removed the master switch and stripped and cleaned the contacts. Then repeat on the inoperative door.
Do not be fooled if the relay ohms out as working!

Disassembled the door panel, all the buttons and connectors.
Checked the motor supplying the direct 12 to the motor. No result- motor does nothing. Measured the resistance with the tester but it shoes no continuity. As if its burned.
Also measured the voltage from the button to motor connector - while not pressing somewhy there is always 12v, when pressing the button down ( relay clicks) voltage goes to 0V
Anyone has a clue, why when pressing button to open the window, voltage drops to 0? or this is normal operation condition.
Window is closed and when i press the button up there is no clicking, only clicks when pressed down.
Maybe someone knows how it should be operating, because know i suspect that failed switch burned the motor supplying in off position the current.
No movement when power direct on the motor shows that the first thing you need to do is find a replacement. I have second hand motors from my XJ40 but not sure if they are the same as the X300 and I am on the other side of the world so probably of no practical use.
What do you think about the voltage in the connector?
Now I have a theory that if I have 12 volts with no pressing the window button, that means motor has a current and load.
Can it be that this constant current burned the motor.
My logic tells me that I shouldn't get voltage with no pressing the button.
Maybe the switch button is defected and burned the motor. What if I replace it and it burns again?
I think there could be a window close relay stuck, that caused the motor to burn.
I wonder are those relays repairable or replaceable or its just isn't wort to do that, simply replace the switch itself is probably simplest solution.
What I found on mine was the locking bar holding the sockets in place was loose , this allowed a socket to migrate and loose contact . Since you have 2 windows acting up I would look at the driver / master position .
In a pinch you can use a battery charger to drive the motor up or down . Just swap polarity on the 2 motor wires . lt's a high current so arcing hazard .

Right side power windows not functioning
