My driver side seat belt does not get back so qick, actually it stops somewhere and before it gets stuck when closing the door, I push it back into the B-pillar.
Cleaned cpl. belt with detergent some time ago, then after drying sprayed it with silicone spray, helped a bit to retract a bit better, but not as good as I expected.
Seems the spring is getting weaker.
Can imagine that while tinkering with that spring it suddenly gets lose and goes off like a rocket.
Any experience?
