Alright, so my rear demister, and heater blower haven't worked since I bought the car.
And the other day I knocked the keys whilst they were in the ignition and the car was running, and the heater blower came on. Trying this again a few times to see if it always happened or was just a fluke, proved that it always happened.
So this inspired me to have a look at how to fix it.
I did so and ended up joining the two brown wires under the steering wheel.
Now my demister works, but my heater blower does not.
All fuses seem fine.
Any suggestions?

Turned the engine on today and voila... the blower came to life too.
Now I know there must be some dodgy wiring.. but where? Which are the heater wires?
