The HRS, the wires always break inside the insulation,(esp on mk4 escorts!!), so a good probe with a test light, first at the connections on the screen for the live, chances are it is broken inside the insulation from constant opening/shutting movement, but easy fix, just use some heatshrink to seal the wire after fixing instead of tape if you can.
