After fixing my heater matrix and refitting the dash, everything is working fine except that the green warning light, that flashes with the indicator light when a trailer is fitted, is permanently on. The wiring diagram appears to show the connections going to the flasher unit. Could this be the problem ? (and where exactly is it ?).
