Fix seat belt retractor

You never attempt to fix a seat belt retractor, you replace the seat belt. This is due to the fact it may save your life.

of course it possible to access this retractor , you just need to locate the small round circles in the lower part of trim and gently pry the covers off , screws will be evedent , you will need a 6 mm star (five sided) drive socket wrench to remove the retractor though

Please check if your seat belt has "Retractors" or "Automatic Retractor".

Follow these steps to determine if you have a retractor system that will hold car seat securely or your seat belt won't retract as should be:

A. Pull belt all the way out.

b. Allow belt to retract about 6 inches (15 cm).

c. Pull out on belt again.

If belt is locked and you cannot pull the belt out any further, you have an Automatic Locking;

If you pull the belt again all the way out and won't return to normal operation, then the mechanism is damaged, but try first the "retractor" lock to be sure. By Federal Law, nobody will sale a seat belt in a junk yard, try the dealer or order thru the dealer the whole seat belt or the mechanism. I hope that is just a matter of the automatic retractor; you can see this information in your car's manual. Try and we will see.

need to remove the plastic trim where belt retracts to slide up out of way and inspect seat belt retractor drum for debris jamming ratchet or against locking mechanism check belt is not twisted and last look for rust

Seat belts are not fixed they are only replaced.

2005 Towncar SRS Code 33 (3 flash + 3 flash, repeat this set for twice. then Beep 5 times pause x 5 = 25 beeps every 30min).

This means you have problem with left (Driver) side pretentioner (Seat belt retract system).
It doesn't mean physical belt or retract mechanism.It is just bomb wiring which is part of airbag system.
When airbag deploy, passenger must stay tight in seat otherwise body lean to front then slam back to seat by airbag.
if belt is loose or delay to lock, passenger's body rocks back and forth.So, system use small bomb (Fire power) to lock and retract seat belt when airbag deploy.There is small bomb and igniter in part of Seat belt retractor.
Code 33 is warning for this part on 2005 Towncar.(older model is different meaning in Ford/Lincoln, it's possibly passenger side airbag system for earlier model)
Before you work for any part of Airbag system and touch any "Yellow connector", * *Disconnect battery (negative side is good enough) and wait at least 5 min to clear all power in system**.(Airbag store back up power for few minutes to be able to deploy even in case if power disconnected)
by the way, you should move your driver seat most forwarded position before you disconnect battery to make it easy to work with seat belt.
locate driver side seat belt retractor (in center pillar between front and rear door, you may have to fight with weather strip)

Locate Yellow connector on bottom of Seat belt retractor (it's called "Pretensioner")it is located on very bottom of rear side of retractor.
only one yellow connector. (make sure your battery is disconnected)
Check its physical connection or looseness.if connection looks fine, you may have to replace whole seat belt ($180-$200 in Lincoln dealer)
You can check if pretensionor is good or bad by regular tester, but unless you know how, I won't tell (because I don't wan't you to blow out pretentionor).

Are you trying to say the seat belt retractor is stuck? This is in the front seat?
If it's anything like my Tahoe, you need to remove the plastic panel that covers the retractor (carefully - don't break the clips or you won't be able to put it back on). Take a large flat head screwdriver and slide it under the part where the seat belt coils up, and find a little tab - push it with the screwdriver. As long as the seat belt is not twisted up, it should retract.

You will most likely need to replace the seatbelt retractor. The best place to find a replacement is usually your local self service auto salvage lot. I replaced mine last year and it ran me $10 for the retractor and u pull and pay.

the springs inside the seat belt retractors wear out over time. remove the trim from over the retractor and make sure nothing is rubbing the belt, and if it all looks alright, replace the seat belt.

I would not try to repair a seat belt. It is a safety issue and the only real fix is to replace the seat belt retractors as an assembly. $250 is a reasonable price compaired to possible medical/hospital costs. A dealership is going to replace the complete retractor because it is the only real fix, and because of the liability involved it your safety. Good Luck
