If the Gauges on your instrument panel have stopped working you may have had a voltage converter stop working. This device mounted to the rear of your instrument panel converts the voltage from your alternator to the voltage that your gauges run off of. You can check the fuses with a multimeter and see if both sides have voltage showing, if so then see about replacing the voltage converter.
The dash light brightness control may be turned off, check the switch.
2002 mazda ,,gauges are still working after taking out key..any ideas
It sounds as if you have a defective ignition switch. The next time it happens you need to turn the key slightly. If it starts working then the ignition switch is bad.
try a switch
I had a 1986 cj that had the same problem. Couldn't find the problem until the dimmer switch on the floorboard went out. Replaced the switch and the gauge lights started to work.
There is no "switch". To cancel overdrive move the gear lever from "D" to "4".
check your ignition switch.

Check your tail lights. If they are stuck on the switch might be bad. The brake switch will cancel the cruise. If a light has a ground fault the voltage will feed back and cancel the cruise. Those are a couple places to start looking. If that's not it, it's probably a little more severe.
Posible relay problem
it does not have a high pressure switch all it has is a evaporator temp sensor/switch.
If the dash gauges in your 1994 Dodge Shadow stop working when you turn the headlights on, it could be due to a faulty ground connection or a short circuit in the electrical system. When the headlights are activated, they may draw power away from the gauges or cause interference in the circuit. Another possibility is a failing dimmer switch that could affect the gauge lighting and overall function. It's advisable to check the wiring and connections for any signs of damage or corrosion.
