So... I think I may have caused a problem under the dash of my truck.
My truck has vinyl interior, and vinyl mat floor. Every time I've washed the truck, I've sprayed out the floor in the interior. Never had an issue doing this... until now. I know, I know... I'm an idiot.
Since I sprayed it out, I now have a beeping sound that's coming from under the drivers side of the dash. The truck will still start and drive fine, but whenever I shut the truck off, the beeping begins. I think I've found the source of the sound, but I can't be sure. It seems to be coming from a black box with blue connecting plugs.
The beep sounds like a slow alarm clock... beep..(1 second of silence)..beep..(1 second of silence)..beep.. and so on in this fashion. It beeps about 5 times, then stops for about 5 seconds, then beeps again in the same pattern. It does this about 3 times before it silences for a long time.
I suspect the beep is coming back periodically as the truck sits because I've heard it beeping in the middle of the night, plus my battery is no longer holding a charge, so I think it's running it down.
It could be your airbag sensor. If i remember correctly if the bulb was pulled or blown for the airbag light in the dash it would beep instead of flash.
100% correct on the airbag light being blown. If its removed or blown out, it'll beep instead so as to alert the driver. I believe this will also happen if the CEL is blown too, but I'm not sure.
We either make ourselves happy or miserable.
The amount of work is the same.
my truck does this if i turn my ignition between the run and on position (like in between the two when i shut it off) kinda wonderd what it was but i believed it was because of my worn out key switch. My airbag light works btw

Recently a black box started beeping under driver side dash only when truck is off. My air bag light flash and is fine. Does anyone have anything else on how to stop it , can I disconnect the box or will it mess with air bags, driver bag hasn't worked in couple year, so not worried if they won't work.
Only when the key switch is off you say? The airbag module should only squawk at you with the key ON. Unless it failed or something.
Where exactly is this black box? The only box I know of that is capable of making noise deliberately is the airbag diagnostic monitor, but that's a BLUE box. At least it's blue on every older Ford that I've seen, before they started using the newer data recorder type.
Thanks but figured it out, I didn't know the air bag light gave off a code too. It says I have code 32 -Driver Side Air Bag Circuit High Resistance or Open. You wouldn't know how to fix that would ya? I don't get why it's just now started beeping, driver side air bag never worked lol, had it checked out over 4-5 years ago cause cruise cont and horns didn't work and we were told it was the airbag and it wouldn't go off if in a wreak,and we never got it fixed. my truck never been in a wreak luckily. Family owned since 94. Is there way to clear code?
No , it's a black box with green front, bout twice as big a black box for door tones, which is behind black and green box. I fixed it tho, just unplugged the air bag module and no more beeping but airbag light stays on when key on but it all good
