If the light was flashing when it came on, then it means your engine is misfiring.
A solid light can mean anything from a loose/faulty gas cap to a transmission issue.
This light comes on when the computer detects a fault of some sort in its diagnostic tests. If it keeps detecting this issue, the light will remain on. If the light turns off, then it has detected that the issue may no longer be present.
In order to find out what the exact reason was for your light, You need to have your car computer scanned to retrieve the code that the computer would have stored when the light triggered. Most garages will do this free of charge. The code will tell you what may have caused the light to initially turn on.

The problem is in the sunvisor light. You will have to take the light assembly off and you will find wires have become disconnected.

Yes, you are on the right track. More than likely it is a defective flasher relay as one relay controls turn signal and hazard flash. The flasher relay is located behind the left side of the instrument panel.
