I have a 91 Dx 4 dr and the driver seatbelt just quit working yesterday. Any ideas what woulod cause this?

 

The fuse is right at the battery, the fuse holder is part of the battery + terminal. Check that it hasn't been ruined by corrosion, and power is actually reaching the two small wires that go to the seat belts. There is a separate fuse and wire for each side.

If it's not something simple like that, reportedly Honda has a lifetime warranty on the seat belt systems. Inquire at a dealer.

 

Well, I did just that. The fuses were very dirty and one was beyond cleaning and blown. Cleaned up the posts and new fuses. Works fine now.

THANKS!!
