My passenger side seatbelt fails to retract....sometimes. It'll certainly go in if you help it along, but I'd like it a little safer. Is this a cleaning thing...or a lube thing? Any ideas how I get at it? New GF is very good at placing belt back in car before closing door (swoon!), but she shouldn't have to. Suggestions? Steve Bigelow 84 5000S "Audrey"
