Turn Signal Flasher Assy Access

[tomp]

My 04 RX300 at 66K miles has been very reliable (apart from rear view camera replaced under guarantee; lower suspension arm bushes replaced last year) but it looks as though the direction indicator flasher assy (pt No:81980-53020?) has packed up. No RHS direction indicator lights Front or Rear flashing with right selected on steering column stalk or with Hazard switch selected. The LHS works as advertised. I've tried to locate the flasher unit which seems to be clicking (with LHS indicator selected) behind the kick panel on lower RHS of driver's foot position. The USA forum provides other alternative locations which I don't trust given LHD and other model differences. This should be a fairly simple replacement job if only I can locate the unit and, if behind the kick panel, remove the panel. I should be grateful if any owner can help to identify the location of the flasher unit and advise on panel removal if necessary.
