Our dash warning buzzer/alarm quit working. This is the buzzer for low air susbensiojn, jacks down, etc. I have looked at many posts regarding this issue but the posts that talk about "repairs" seem to only work for Actia brand gauges and I'm pretty sure I don't have Actia gauges (see photos below).
We do have the Vansco system and other posts, as well as the Vansco Input/Output guide on the ACA Tech site makes me think it is not Vansco related.
Before you say it, yes, I've tried the magic cure-all of turning off the Master House and Chassis battery switches for a few minutes and turned them back on. No help there.
The buzzer sound didn't just quit, it quit, then worked again for a few weeks, then quit for a day, then worked for a few days, and now hasn't worked the last couple of trips.
I have removed the screws holding the burl wood (plastic) dash to look at the back of the gauges and to see if there are any electronic devices (buzzer?) nearby and didn't find anything. There are no little "speaker holes" on the back of the gauges for any sound to come out of. And I looked on the back of the "dash light (idiot light) cluster" and again find nothing that looks like a buzzer.
I have asked another 2004 owner where their buzzer seems to be and they say theirs sounds like it's on the firewall to the right of the steering column. I have looked there and don't see anything that looks like it is designed to make noise (no buzzer, piezo buzzer, black box, etc.) So, now I wonder if any of you 2004 owners know what this gizmo looks like (photos anyone?) and where it lives? Or maybe what it connects to so I could follow some wires leading out of an item I can identify. Thanks all!
Here are a couple of photos of what the dash looks like. These gauges don't have any brand name on them:
