I have the following problem: My right passenger side seatbelt won't retract most of the time. My local dealer shop has told me the problem is with the sensor. But it's the first time I've been to this particular shop, and the mechanic's manner didn't inspire confidence. He didn't appear totally convinced himself this was the problem, though he recommended I order a new replacement sensor. My questions: (1) I've been quoted 0 parts and labor. Is that a fair price? (2) Where is the sensor located? I have a friend who's an electronics whiz whom I could ask to look at it. I've bought and looked through the Haynes guide, but it's a bit lacking in this level of detail. (3) From my googling, this doesn't seem to be a common problem. Is there something else I could suggest might be a problem, so I don't appear to be the total rube that I am? Thanks! Nina Jensen '91 Accord 4-door LX
