I have a 2000 honda prelude and the drivers' side seat belt SAGS LIKE CRAZY! Everywhere I've looked online they say to leave seat belt repairs to the pros. After all...your messing with your safety! But I took my shit apart anyway! Haha, I got it back together, but I had no luck whatsoever in tightening the tensioner. does anyone have any suggestions or am I doomed to take it to the dealer? Also does the dealer usually cover any repairs on the seatbelts?
