Air Bag Light Flases 5 Times...???

[OiDALE]

Ok, this is driving crazy, a couple of weeks ago my air bag light came on in 5 flash burst with a couple seconds between...It flashes 5 times and keeps cycling over and over again while the car is on. Its a 1991 GT. It just appeared one day after the car sat for a couple of days. Its a garage kept car so no outside elements.

But about 4 days ago the light went out and a beep from under the das replaced it with the same sequence. A couple of days ago the tone was replaced by a broken tone like a crackle, seemed like it was breaking up (loose wire)...Today I went underneath the dash and found a little whit box where the tone came from. I moved it around, unplugged it and plugged it back and the tone stopped.

Now the light is back...Please help me out??? Its a 5 flash sequence which goes on and on...

Not a digital tuning question.

Moving to Tech where you should get a better response.

Does your horn work?

It could be a bad clockspring, one of the crash sensors, the safing sensor, the air bag, or some wiring.
Highest probability is the clockspring.

BTW, once you fix the fault, the diag monitor will then flash a code 10 indicating that the internal thermal saftey fuse is blown (on purpose by the diag monitor to prevent an accidental deployment if a main sensor was bad). So, you will then need a new "air bag controller". They are ~$30 from places on car-part.com .
