jbk,
I had grovel upside down under the dash to see where Mr Morgan had hidden the flasher unit on my 97 +4.
At first I couldn't find it but all that blood to the head gave me an idea & I switched on the hazards.
Tracking down the noise my relay was in that mess of wires behind the central 4 gauges & switches held in place by being wrapped in insulating tape to the loom.
A new relay is now on order from e bay.
