The front seat passenger side seatbelt on my 1993 500 SEL does not retract as it should. I need to replace or repair it and I know it has a cartridge activated retract mechanism as part of its design. I have read some previous threads which seem to indicate that device may have been activated due to a collision of some sort, and indeed the right front fender has been repainted. I also have seen where someone said the battery power should be disconnected before removing the squib wires on the cartridge device.

I would appreciate any advice on what it takes to remove and replace, or even repair, this seatbelt.
I submitted a PIR at the Partshop page a few days ago.

Thanks.

Scotty
