Seat belt stuck on 1995 850 volvo - 1996 Volvo 850

I solved this on my 95 volvo 850 glt as follows:

pull the seatbelt pilar cover off from the door jamb. this runs vertically up the pilar between the front an back door (beside the front seats. Once opened loosen the belt by gently pulling the belt upward toward the roof. You'll have to do this sometimes in small increments. Once the seatbelt is pulled out all the way, spray small amount of lubricant into the joint where at the top of the belt spool. Also use a screw driver to push spool upward while pulling the belt. At first it's only going to release a little but eventually the lubricant will work its way into the seam at the top of the belt spool and loosen up the stuck inertia catch. Until it completely loosens you might have to remove the pilar cover again and work the seatbelt out (also use the screw driver technique described above) in order to use the seatbelt. When parking, I would relatch the seatbelt and pull the slack up around the back of the head rest. After a day or so it worked normally.

Remove the the seat belt mechanism, open it up or try to replace it. Before you do this try pulling it fast toward the roof of the car. Good luck

Thank you so so much,as you have just saved me $311 (australian $)
This was the price from Volvo less labour for a replacement seatbelt. I followed you directions and all is now good. Thanks and lots of good karmer in your general direction!!
