Short to power. Could be as easy as just pulling a fuse and reinsert it. Sometimes you have to access the plug and do they same thing. Sometimes you have to fix or replace the plug. If your display is the radio, It could be internal radio problems..

Probably bad speaker, but you might check all wiring to it for loose connections.

an if the radio is not playing then does it do the same or is it the radio causing it

Mine did this after kids played with it, just hold the power/volume button pressed down for a few seconds and it will go back to normal.

if the fuse has not blown it could be the ignition control module it controls the dash and a few other things.

There is only one radio fuse. If its playing music, its not the fuse. Your radio has most likely failed internally. You probably need to replace it. Check on used ones if its not a navigation radio.($175.00) If it is buy a reman from a dealer. ($900.00 Exchange) Rough idea on prices.

I don't think it is a fuse.
The warning chimes for this vehicle come through the radio and are play to the speakers and if I remember correctly the chimes play to the left front speaker.
I would check for a faulty speaker or wiring to the speaker.

This color code works for 87-93 mustang factory radio; it might work on yours as well. I'm not sure if it has the same fuses though.
