sun roof on 1998 Chevrolet Cavalier

my sunroof does not open but it has power to it and seems to be jamming.

If you can remove the sunroof motor from the track assembly then do so and see if the motor will run ok. If it does then chances are that the cables in the track assembly are stuck, the complete track assembly may need to be replaced.
