im not sure if the noise that u are hearing is the same as mine, but i had a similar sounding problem with my 89. if u really want to do it urself, ur gonna have to take the door panel off any way. take if off and see what u got. when i had this problem, all that was wrong was the window had come out of the two small clips that hold the window in place. if this is the case, go buy some super strong rubber cement type glue that is ok to use on glass and plastic. clean the window and the clips really good. i even used some sand paper to rough up the spot where the window slides into the clip just for a better grip. place the window inside the clips and roll the window all the way up. try to mark or some how keep the clips in this position while u roll the window back down far enough to where u can see the clips.(the one on the right is going to be harder to get to) lift the window out of the clips and apply the glue to the inside of the clips.(i used a q-tip) slide the window back into the clips(keep in mind the clips need to be in the same position as when the window is completely rolled up. this is because the clips have limited room to move and if you glue the clip too far to one side, when u roll the window up the clip will move and the glue wont be able to hold the window.) once the clips are in place and the window is in roll the window up and keep it up for a few days to let the glue dry.
if this isnt the case, then i apologize for the long message.
