2004 Crown Vic had right rear door replaced, they didn't hang hinges carefully and door wouldn't open easily. I unbolted the front seat belt pretensioner from the door post to access the lower hinge bolts and when I put everything back together the seat belt won't extend. Unbolting the pretensioner again allows it to retract even further but it won't extend.
Is there a quick fix or do I have to buy another pretensioner? And what to I do to keep from causing the same problem on the replacement?
