Was told by the previous owner that the air bag light stays on because of clock spring broken, although sometimes when warm light goes out , wanted to know if a clock spring from escort car would work if i cant locate one from a van and also the procedure for fitting it.
Also the rear door only clloses with a massive slam, looks like there maybe a spring broken inside, those star shape bolts are they Torx ?? and what is the size

1 Disconnect the battery negative (earth) lead
(refer to Chapter 5, Section 1).
Warning: Before proceeding, wait
a minimum of 15 minutes, as a

detachable lower facia panel from beneath
the steering column.
3 Disconnect the multi-plug from the module,
by pressing the locking tab upwards and
swivelling the retaining strap.

Regarding ASH comment " it is the front impact censor in the car that rust out on one of the terminals so it thinks the bag is faulty"
