If the sunroof is motorized which is what im assuming by the way the question is worded the part that opens and closes it would be called a sunroof motor. Simply by typing in 1995 saturn sl1 sunroof motor in google search. You might want to do some pricing comparisons on this.

It also might be a good idea to bring your car to someone with an voltmeter before you purchase anything so they can test to see if it is actually the motor that is bad or if your wiring is or something else is fault so you dont spend money repairing it and find out that it wasnt the motor that needed to be replaced.
