driver window on 1993 Volvo 940

the window won't go all the way up and makes a chatter type of noise when the switch is pushed. Is the panal hard to pull off to see what is going on

this Volvo uses a regulator with motor; they are not sold separately. door panel is fairly easy; replacing
the bad window regulator is hard.
