A good fellow on here named Scott has sent me 2 flashers to test out, I will be testing them today, or tomorrow.
Still no clue's on the other stuff, though I have not fussed much with it. I will wait till the car is on the road, to do any real life diagnostics with the air conditioning.
I am not starting the car right now, so I don't want to kill the battery in attempts to sort these issues out.
