A commen problem on 3dr's is that the fuse box melts where the fuse is for the fans.

I cured this with a seperate fan loom.

Indicators are on fuse 9, this also does brake lights and reverse lights.

My heater fan has also stopped working since the car was off the road, am just going to replace this as i checked the wiring on mine and there is power in positions 1-2-3 so i assume it has to be the fan unit itself

I know i have not answered all your questions but i hope this is of some help to you
