What's wrong?
The Weldon V-Mux Vista IV Interface in the 2020-2021 Hi-Tech E.V.S. Spartan Metrostar and Spartan Gladiator is an electronic control panel with an LCD screen. On these emergency vehicles, that display is used to control emergency lighting and HVAC functions, so it is more than a dashboard screen. It is a control point for equipment the crew uses during operation.
The problem starts when the display sees a low-voltage spike outside the range it handles cleanly. The display is designed to restart after that kind of electrical event, but affected units do not always restart successfully. When that happens, the LCD screen locks up or stops working. Differences in vehicle wiring and electrical installation can change how often the display sees those negative voltage spikes.
There is no warning sign before failure. The screen can work normally until the electrical event occurs, then lock up or go nonfunctional without a prior alert.
