    ALL my doors windows work and they can be push up and down individually from their own button.
    3/4 windows can also be controlled by the drivers master switch, but the front passenger side window cannot be controlled by the master switch.

    After a lot of measuring voltage and continuity checks, the wires were all fine. Then i decided to take the plug controlling window A movement out and not putting it power i also did this to the window B on another passenger window now suddenly A work but B doesn't. i did this again an now both A and B doesn't work and then took the wire out and back in now only A works.


    I am confused to what is happening and why they randomly work when i take the wire out and put it back in.
