PAS, heater fan , rear demister Repair.

[Vollty]

Hi all!

Just brought a saxo scandal (lovely color scheme!!) for my daughters first car.......needless to say the demister & fan does not work!
Have done a test, joining the two brown wires & all is fine.
My question is why do others recommend using a relay in line? I can't even work out why these wires run through the ignition switch. As far as I can see, power does not run through these wires when the engine is not running, so why do they run through the ignition switch? In other words I can see no difference between the original wiring set up or just joining the two brown wires together!
Any thoughts?

This happens to me but while im driving
i figured that if i whack the cover under the steering column it works again. i have checked under the cover and those wires seem fine.
