Where is the Window Screen Washer fluid reservoir for the rear window, on a 1995 Nissan Sentra Wagon?

From the 2013 operators manual;

Push the windshield wiper lever forward to spray washer fluid on the rear window. The lever returns to its starting position when released.

The windshield washer reservoir is used for the windshield and the rear window. Check the fluid level in the reservoir if either washer is not working.

Yes it does and the washer fluid reservoir under the hood is for both the front and rear. The following is a diagram of the washer pump and hoses so you can check for operation or leaks.

Just one.Check the lines and the pump at reservoir,

WINDSHIELD WASHER FLUID RESERVOIR
Part #: JLM12455 RESERVOIR, WINDSHIELD WASHER FLUID, FITS 1995-1997 XJ6. This is the large lower reservoir the top filler tube will need to be removed from your old reservoir ITS ABOUT 155.00

normally one reservoir does front and rear

the front reservoir is the same reservoir for the front and rear, you should see two pumps on the reservoir

they share resivor. if you cannot find it trace the hose from your washer fluid nossle.

Assuming the reservoir has washer fluid in it - when you activate the washers with the key on do you hear a hum from the pump? When you activate it do you see fluid coming out under the car? If any of the lines are damaged the fluid may not be travelling where you want it to. If the pump is not working altogether check to make sure the wire is plugged onto it. Check the tubing from the pump to the connector under the hood. If your fuses are good and the pump is not working at all have the plug checked for power. Pumps go out, but the cause is usually something more simple and less expensive.

the pump motor likely is bad. get a used washer fluid reservoir at a pick n pull yourself or at car-part.com. page with * is lowest cost.
