Help please?!!!Do not know if this is a small or big issue.

If the warning light is only on when the park or headlights are on, it's one of those circuits. If the warning light stays on even if you turn off the park and headlights, it's the brake lights at fault.

For park you have front corners, rear corners, tail lights and license plate lights; two bulbs per. It's typical for a rear corner bulb to not illuminate because of a poor design on the bulb holder. For headlights you have the headlights (duh!). For brake lights there are the pair of brake lights in the tail light cluster and the center brake light in the cabin.

When does the warning illuminate?
-- When turning on parking lights (one click to right)
-- When turning on headlights (two clicks to right)
-- When pressing on brake
-- When using turn signals
That will help you to know which bulbs to check. You may have to remove each bulb in turn, checking for corrosion of the base or the socket, loose connections, disconnected filaments, etc.

The circuit also will trip if the two small side marker lights on the rear light assembly are not working. It will also trip if the license plate lights are out.
