So driving along listening to radio when suddenly the dashboard emits a piercing shriek, continuing while i drive a few blocks to the next red light and shift out of Drive and back. Then while rolling along a few blocks later, a momentary shriek for 5 seconds stops on its own. No check engine light, normal temp, plenty of fuel, nothing odd on the radio screen, AC off, lights off, etc. Van is vanilla with regard to theft alarm pats and such bells & whistles.

Wazzat all aboot?

perchancetodream,

Have you ever watched video of building implosions ?
It's Ford's version of the imminent explosion siren.

I’d look at the HVAC system, the actuators that operate the dampers can make some weird noises, and blower motor bearings can fail in a very noisy way.

Otherwise I’d guess the AC clutch is causing a loose serpentine belt to slip.

It’s definitely an electronic noisemaker, sound is not coming from the engine compartment and the HVAC was off.

Apocryphal story from Whole Earth Catalog days. Guy went to surplus auction in San Diego. Bought a big cabinet with lots of knobs switches gauges and rotary number readouts. Got it home, found a cord, plugged it in and the thing powers up! He starts flipping switches and fiddling knobs. Something clicks and a bell starts ringing. More switch and knob fiddling, but bell keeps dinging. Then a klaxon starts up AHOOGA AHOOGA. Guy gets scared, runs out of garage. His house blew up. It was a submarine captain’s code safe, complete with self-destruct armament.

I finally was able to pull over while the beeper was shrilling and tracked it down to the monitor for the rear view driving camera system. Not a Ford thing. Not sure what's bothering the monitor. Maybe a semiconductor board going bad. Pushed its buttons and it shut up. Worst case scenario I open up the case and snip snip.

Look for loose connections / debris on or near the sensors in the rear of the van? Maybe some interference with anything on the hitch? Just some ideas. If not I would probably clip or unplug the beeper too, it is plenty annoying when backing up.

No rear sensors, just sealed cameras. It's an aftermarket rear view dual camera system with narrow and wide angle views. Blackbird by ICU Car Cam Systems. https://www.fordtransitusaforum.com/984986-post1.html

I contacted Dave Ruiz at https://www.carcamsystem.com/ about the beeping from the mirror-mount monitor. He replied he really don't know why it would do that other than a short defect, and offered to send a replacement monitor at no charge. That's service!

Be glad it's not a shrieking child in there! Hope you get it figured out.
