mystery buzzer
When I bought my bronco a few months ago, I had a buzzer going off about every 50 miles or so.Had some work done to it and the buzzer did not do it again. The other day driving down the road it started again, but did it once. Coming home to night it seames to do it every 5 min. Cant figure it out. Thanks in advance.

Can you describe the sound or the source? Is it a buzz like an old seat-belt buzzer, or more like a card in bicycle spokes? Is it coming from the L or R side of the dash? Or somewhere else? Next time it happens, slow down and see if the buzz changes with tire or engine speed. Then try changing the fan speed or hitting the dash.

Ha, Ha, self destuct did not think about that. No really the buzzing noise is a buzzer device, not a fan or tires. It's 5 buzzing sounds then a pause then 5 more pause. It does this about 4 times then quits for a while. The repairs done to it before where the clock spring and the manual lever position sensor the noise comes from driver side from what i can tell

Straight off the Ford/Helm service CD:
The supplemental air bag restraint system (SRS) is powered directly from the battery. The supplemental air bag restraint system can function with the ignition switch (11572) in any position, including OFF and LOCK. The supplemental air bag restraint system can also function when the front seat (60012) is unoccupied. The electrical system performs three main functions:
l Detects impacts
l Supplies electric power to the igniter(s)
l Monitors the system to determine system readiness
The electrical system components include:
l Air bag diagnostic monitor (14B056)
l Air bag indicator
l Wiring harness and air bag sliding contact (14A664)
l Sensors:
-- Primary crash sensor and bracket
-- Safing air bag sensor
l The igniter within the driver side air bag module (043B13)
Sensors
WARNING:
VEHICLE SENSOR ORIENTATION IS CRITICAL FOR PROPER SYSTEM OPERATION. IF A VEHICLE EQUIPPED WITH A SUPPLEMENTAL AIR BAG RESTRAINT SYSTEM HAS BEEN INVOLVED IN A CRASH WHERE THE RADIATOR SUPPORT, FRAME RAILS OR COWLS HAVE BEEN DAMAGED, INSPECT THE SENSOR MOUNTING BRACKETS FOR DEFORMATION. IF DAMAGED, THE SENSOR SHOULD BE REPLACED WHETHER OR NOT THE AIR BAG IS DEPLOYED. IN ADDITION, MAKE SURE THE BODY STRUCTURE IN THE AREA OF THE SENSOR MOUNTING IS RESTORED TO ITS ORIGINAL CONDITION.
NOTE:
Undamaged sensors will reset automatically after an accident and can be reused.
The sensors are electrical switches which react to impacts according to direction and force. Sensors discriminate between impacts that require air bag inflation and impacts that do not require air bag inflation. When an impact occurs that requires air bag inflation, the sensor contacts close, completing the electrical circuit necessary for system operation.
Three sensors are mounted in the vehicle. Their locations are as follows:
l A primary crash sensor on the left-hand side of the radiator support.
l A primary crash sensor on the right-hand side of the radiator support.
l A safing sensor at the right B-pillar.
At least two sensors (one primary sensor and one safing sensor) must be closed to inflate the air bag.
The sensors automatically "reset" after a collision and do not need to be replaced unless they are physically damaged. Replace only if proper alignment is not possible due to bent brackets, cut wires, smashed connectors, etc.
Air Bag Indicator
The air bag indicator will light continuously for approximately six seconds whenever the ignition switch is turned from OFF to RUN if the air bag is working properly. If system fault is present, the indicator will either fail to light, remain lit continuously or light in a flashing manner. The flashing manner may not occur until approximately 30 seconds after the ignition switch has been turned from OFF to RUN. This is the time required for the air bag diagnostic monitor to test and verify any and all system faults. If the air bag indicator is inoperative and a system fault exists, a tone will sound signaling that the air bag indicator is inoperative and a system fault exists. Refer to the «Diagnosis and Testing» portion of this section.
Tone Generator
The air bag indicator is the prime means of determining the supplemental air bag restraint system status. However, if the air bag indicator is inoperative and a system fault exists, a tone will sound in a pattern of five sets of five beeps. If this occurs, the air bag indicator will need to be serviced before further diagnosing and testing can be completed. Unless serviced, the supplemental air bag restraint system may not function properly in the event of an accident.
Sounds like the bulb is burnt out. Change it, and you should be able to count the blink code.

I've also read plenty about airbags deploying without warning. Consider that one.
I've never been a big fan of explosions in my face while I'm wrecking a vehicle, but that's just my opinion. I don't think that airbags are going away, however.
