I replaced the headlight wiring with a relay kit as the existing wiring had melted. Now both headlights are working and they seem to be brighter.
Also removed the front door trim and factory clarions. lol:
Unfortunately I was frustrated in my attempts to clean the blower and resistors. For some reason there's a big piece of molded plastic instead of a metal panel behind the glove box... perhaps a 'feature' of the right-hand drive version? I'll look at it again tomorrow, might have to cut it away or remove the dash entirely to clean out the leaves before they start a fire.
