On my 07 Bravo the safety belt on drivers side is too sloopy, when i put back. I think the seat-belt pretensioner is not good. Could i repair, or i should replace it?
In time the belt gets filled with dirt and sweat and grime.. that makes it retract slower/ get stuck.
Try to clean/wash the seatbelt in place; just pull it out as much as it will come and clean it with warm water and soap/carpet cleaner.
