Question
I have a 1994 volvo 940 wagon my power windows just stop working no fuses blew

Answer
Anthony,
Ok then test at the master window switch for power. If there is power the switch is at fault if no power look more closely at the fuses and circuit breakers.  Wires sometimes break in the door jamb. If when this happens can you "jiggle" the ignition key to see if the power returns and all begins to work. That would indicate the ignition electrical switch is bad.
