sounds like you need to replace power window master switch
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.
To install a master switch for the power windows on a 1997 Buick LeSabre, first disconnect the negative battery cable to ensure safety. Remove the door panel by unscrewing screws and carefully prying it away from the door frame. Disconnect the wiring harness from the old switch, then connect the new master switch and secure it in place. Finally, reattach the door panel and reconnect the battery to test the new switch.
If none of them are working then you could have a master switch or relay defective.
no power on the power windows switch
a master switch is a switch which is the power to evry thing in the billding or factory
more than likely you will have to replace the drivers side master switch
Power windows I assume. Check the fuse. If it is still good, it is probably the drivers side master switch that is bad.
did you check the fuses first? Do you have power to the master switch?
The drivers side switch is the master switch; all power goes thru this switch. Pop it out and test for power; you may just have a bad connection at the switch. I would also check the window lock switch and bypass it to make sure that is not the problem.
Because the master control on the drivers door has separate areas for all windows. Start by checking power feeds at the drivers door switch.
