Mazda 2 Dashboard Lights

For the dashboard check you fuses. Sometimes it is that easy.
You will need to repair the dashboard lights to find out if there are any warning lights showing. We're there any warning lights before the dashboard lights stopped working?
What exactly does it do when you crank the engine? Just crank? Crank, try then stall?
Have you had it plugged into a diagnostic scanner to check if it's a faulty sensor?

Sounds like a blown fuse to me. Check your fuse boxes, usually located in the engine compartment, as well as near the driver side of your dashboard, usually near your hood release, or possibly on the passenger side of the dashboard or in the glovebox. Remove the cover for each fuse box and read the diagram on the inside of the cover to find where the fuses are located for each item.

It means one of your side lights is blown. The lighting computer does a periodic check of all the lights and flags it on the the dash if one is bad. Turn on the lights and walk around the vehicle. Also check the blinker lights.

check the fuse box for blown fuses as a first step

All tho the headlights are working do the side lights work also worth checking the dashboard dimmer switch

When the dashboard lights in your vehicle malfunction or cease to operate, the resulting effects can range from being a mere annoyance to posing a safety hazard. Locating the problem and finding a remedy is essential. To fix dashboard lights that won't light, follow these suggestions

Evaluate the problem methodically. Begin the process by trying the simplest of solutions first. Most vehicles have a dashboard lights control switch that will dim the dashboard lights, as well as turn them off. Check the control switch, which should be located on the console near the steering column, make sure its in the correct position to have the lights on.

Check the dashboard light fuse. A blown fuse can disable the vehicle's dashboard light. The fuse box may be under the hood, or on the floor, near the brake pedal, or there may be 2 fuse boxes in both places. Refer to the diagram on the fuse box cover to locate the correct fuse. Replace the dashboard light fuse if necessary.

If all of the above don't fix it, then replace your light switch.

You don't indicate what kind of vehicle you have but my guess is you have a cross feed between the dash light circuit and the ignition circuit. You'll probably have to isolate these two circuits (not an easy task).

I would start at the left brake light. Check the bulb and wiring. Your brake light could be grounding through the blinker circuit.

operate your instrument panel dimmer switch. If this does not rectify the problem replace dimmer switch

does your vehicle have tilt wheel...that is a common problem and your brake light wires run down through the steering column
