i just bought a 94 saturn sl2 and the automatic seatbelts dont move

 

check fuse

 

The automatic seat belts were problem prone. The cable would jump the wheels that guide it and tear them up. Mine were repaired early on with a factory recall. Today? If the fuse is blown and that is all it is, you are lucky. Usually the problem is only drivers side. That is the highest used one. If both are bad probably the fuse. If that don't fix it and you can verify volage is actually there to run the motor, in fact the motor probably runs, you can hear clicking noises as it tries to move things. Forget it. No parts, extremely difficult to get to. I have no idea how and personally would not bother trying to find out.
I always like the idea. I have owned two cars that worked that way. The Saturn as I say was fixed by the dealer and still works now. The mitsubishi when it quit, it stayed that way. The are a maintainence headache.

 

there is a passive restraint control module under the center console cupholder. usually one spilled pop fired it out. expensive as new, likely impossible to find at a yard at this point. Per unc, not worth it at this point if fuse is not the issue.

Two metal latch plates should have shipped with the vehicle to be inserted in the rearmost position of the door track in the event the motors failed, this giving you the ability to safely latch the seatbelts in the proper position. Check the glove box for them.
