From the Driver's window switch cluster (4 switches), the electrical link to the windows is through the multiplex network (body control data bus). Since the network is reporting errors, that may be why you cannot operate the windows.
Check if you can operate the rear windows from the individual switches located on the rear interior door panels (vehicle must be on, but engine does not have to be running). These switches bypass the data bus and connect directly to the local window control circuit.
I now realize my Post #16 was based on a false premise . While the rear window switches do connect directly to the motor driver, a functioning multiplex bus is still required to operate them. Refer to the attached left rear window schematic. The only source of power is the 20A "Door R/L" fuse, which connects directly to battery. I know this wire is powered at all times, because I tapped it to add courtesy lights to my NX. The courtesy light turns on whenever the door is open, even with the car turned off. However, the power window does not function until the vehicle is turned on (Ignition or Accessory). This means an Enable signal must be provided over the LIN bus before the window can be operated.
Conclusion: the rear windows do not operate because the multiplex bus is not active. Until the defective nodes are addressed, numerous systems will not function.
After assembly headlamps, DRL's, Radar in one piece all windows suddenly started to work! Do not ask me why
Now I have one message - "Parking assist unavailable" but it probably jut information saying that parking sensors are blind for some reason. On this forum I found that it should disappear after some drive (Car is not registered so no one trip yet done). https://www.clublexus.com/forums/es-...available.html
Still I have glowing that yellow rectangle with exclamation sign. Need to scan for errors this weekend.
Happy New Year 2022 !
