Auto shoulder belt will not close on 1989 Toyota Cressida?
the automatic shoudler seat belt module (one for driver and one for passenger side) went bad and needs to be replaced. try the junk yard for the cheaper price.
The knock Sensor in a 1989-1992 Toyota cressida is located under the intake manifold, closer and under the cold start injecter. Behind the alternater. i had to use a small mirror to see it, or you can put your hand under and search for it.
