Does the window switch on the drivers door control all the power to the other windows so if the master switch is bad then no windows work?

Yes, in many vehicles, the driver's door window switch acts as a master control for all the Windows. If the master switch is faulty, it can prevent power from reaching the other window switches, resulting in all Windows being inoperative. However, some vehicles may have separate fuses or circuits for individual Windows, so the exact behavior can vary depending on the make and model. Always check the vehicle's manual or consult a professional for accurate diagnostics.
