Is this the module under the drivers side dash?
Can my module be repaired, or better to outright replaced with used one from ebay? 1995 E-150 conversion van, 5.8 auto tranny w/ overdrive

 

It's often a broken circuit trace in the clock-spring tape (maintains circuit during steering wheel rotation) Certain years are very expensive to replace or even find. The clock-spring for my 94 sells for $340. I rebuilt with new ribbon for $20 but discovered the problem was elsewhere. Probably in the control module under dash as you have identified. I went no further and drive it as-is.If you decide to remove the bulb in the instrument panel you will soon start hearing a screeching tone. Sometimes sounds like morse code. That's the miniature speaker in the Control Module acting as a redundant alert when the bulb has failed. I desoldered and removed mine. Sometimes it takes a lot of work to live a dangerous life. I guess we just didn't notice it as much in 1964.

 

My airbag lite does the same thing, i replaced the seat belt on drivers side. But havent gotten around to re doin the wires. The cable got frayed then broke. Its a air bag they didnt have them in the 80s.

A piece of electrical tape over the light in the dash fixed it for me.

 

Bottom line, I did that first and should've stopped at that point.

 

My cable on the drivers side snapped too, so much for technology, never have I had a belt snap, not even those in the junkyard. I bought a junkyard replacement, that ram looking thing on the belt must be expensive, new is almost $200, it has electronics in it linking to the airbag I think, wonder if it's why my light is on.
