After checking my master switch, fuse, I decided to check the motors on the rear windows that wouldn't go down. If yours won't, try this. remove the 2 screws holding the speaker grille on, carefully pry back the thin plastic shield over the motor. Thenwith a small hammer tap the motor while someone turns on the ignition and holds that window button down/up.
Some licks later first the drivers window started working fine. The passenger window was sluggish denoting I need to replace it. You might get lucky.

 

Sorry, 92
