Nissan Repair: 91 Maxima GXE locks and windows, fuse panel, volt ohm meter

Question
My locks and windows suddenly stopped working, they don't work with the master switch, the key pad on the door or with the key (the key just opens the drivers door instead of all of them).  The trunk release on the door panel doesn't open the trunk either.

From prior posts it would appear you might direct me to the door master switch (although the others didn't seem to have both Windows and locks at the same time)?  If so is it possible to check it before replacing it?  Also, I couln't find a fuse marked doors/windows, should it be under the dash or in the engine compartment

Appreciate any help, this forum is excellent.

Answer
Check to see if the circuit breaker on the fuse panel is good for the locks and windows.  If it is good then it is the master switch.  There is really no good way of checking the master switch unless you have a volt ohm meter and have the skill to back probe the circuits going into the master switch and out of it.  But, since you say all the windows and door locks are not working I would really be looking at the fuse panel first.
