Question
I HAVE A 1995 BUICK REGAL,LAST NIGHT I ROLLED THE BACK PASSENGER WINDOWS DOWN NOW IT WOULD NOT GO BACK UP.THE OTHER WINDOWS ROLL UP FINE IT IS JUST THE BACK WINDOW

Answer
Hi Gloria,

It is very difficult to diagnose your problem without more information.  There could be several reasons why the window will not go up.  For example ....

1.  a bad window motor

2.  a bad window switch (either single or master)

3.  a faulty connection at the single switch and the vehicle wiring harness

4.  a broken wire between the master switch and the right rear window motor

5.  a corroded ground wire in the electrical system

Because there are so many possibilities I think you may need to take the vehicle to an experienced mechanic to uncover the problem.

If you have a bit of mechanical aptitude and a 12V test light or electrical meter I will do what I can to give you some guidance.  Just send a follow up question letting me know how I can help.
