How can i manually release my automatic seatbelt which is stuck on its track in the half way position? 93 saturn sl2 4dr.

When a seatbelt locks up it is usually due to dirt or corrosion in the automatic locking mechanism. The mechanism can't release because it is under tension. If you get into the cover that houses the release mechanism for the seatbelt, you may be able to hit it with a little wd-40. You do have to release that tension so that the lock will spring back to the open position and allow the seatbelt to retract. Try the lube. Sometimes the galvanized coating on the internal parts causes a seize.

Check the pink wire that goes to the latch inside the door. It's is likely broken or loose somewhere.

You may have to replace the seatbelt positioner.
Check with Saturn (or their replacement GM division) to find if the warranty is extended for seatbelts (some manufacturers cover seatbelts forever) 800-553-6000

middle seat belt shouldn't have anything to do with it. The seat locks down for stowage in the rear cargo area. you can pull the release handle on the back of the seat to release it back into the up position.

It Needs Either a New Seat belt track assy. on the side that's not working or a new Seat Belt Control module Located under center console (Blk Box With 3 Connectors) One Fuse works both tracks

it is likely the relay that is stuck on .... if it's not labled in the fuse box let me know and i'll find out which one it is

Its probally off the track, you should take the molding off and move it up and down to see if it moves/slides freely,as for them both not moving  does the other functions work proper when the belts are suppose to move because if they don't it may be the ones under the hood (which I cant think of the name of them right now)you know the bigger ones.

You'd need to pickup the need parts at the junkyard. You'll need the "A" to "B" pillar trim, lower "B" pillar trim, front seat belts and seatbelt giude from a 1995 SC1 or SC2.

The treaded hole in the frame of the car where the track of the automatic seatbelt assembly attaches is in a slightly different place than the three point system. Its not a problem though. You just need to drill a 3/4" hole slightly above the existing hole in the trim panel. The existing hole is hidden by the seatbelt and not noticable at all.

Everything else pretty much bolts or snaps into place.

I've done this swap on several 1991-1994 Saturn S-Series.

The motor I believe, is located in the pillar between the doors. Remove the trim and pull the plug on the motor itself.

The fuse is in the center console, left side of passenger footwell. It is labelled PREST. for passive restraints. Possibly check the restraint module located in the center console, just under the E-brake lever.
