You could pull the door panels off and run the motors manually by connecting the leads to a battery to see if it works (P-N window up, N-P will go the other way) and thus eliminate the motors as an issue.
Might check the connectors to the driver door switch as well as the pass-thru on the driver door hinge area.
If there is a break or fault on the driver door, the rear doors still won't work as it is a whole series system.
**I'm using experience from Ford vehicles on this, I haven't wrenched on a Toyota yet, I'm assuming that they're the same type of system. If not- maybe someone else can provide assistance as well.
