eek, here's a quick way to see if any current is being drawn when you try to activate the motor. Get a digital voltmeter, connect it across the battery, turn the key to on position, either you or helper watch the meter, activate the front or rear switch. If the motor is stalled or jammed, you will see a voltage drop. If no voltage drop, then either switch(s) wiring or motor is dead. Windows are fused in opposite corners, ie, left front, right rear, right front, left rear. Make sure the window in front opposite the rear that is not working is functional. If not, replace fuse. If working, then you will have to dig into the door and motor..
