96 park avenue none of my windows work, do you think this could be a main window switch issue

check all fuses and relays associated with the power windows first. and check the wiring especially where it goes into the doors where the doors close.

some brute pushed the buttons....perhaps someone carrying something like a guitar case placed the weight on the buttons...and now the can had undone itself...someone must carefully take the door apart and the switch is held together with tabs that bend...and no longer connect the switch...so with a big pliers put them back together...put the door on and you're done~
