The fan speed is controlled by a 4 position rotary switch - very inacessible and has died. I have the connector off the back with 4 cables. White/grey black blue and green(?). White has power on it.
Anyone help with how to get me home ? It's raining hard and the windscreen steams up.
White to blue - speed 1 , white to green - speed 2 , white to black - speed 3 ??
thanks

You should have a live on the light blue and the 1-4 speeds are: blue; grey/red; white/black and orange respectively.

You'll just have to wing it; both my data sources give the same colours - but Fiat are notorious for changing these things.

the blower on my car doesn't work either - yes it gets misted up standing still but clears after a while under way. Be careful what you wipe the window with; a sleeve or glove may just leave you with a dripping wet window just as hard to see out of - you need to dry it to see out of it. Any towels you could 'nick' from work.

Looking at a truly terrible diagram in a "Lyndsay Porter" 6 car book - it shows the wiring, but not the colours inside the blower unit, only external wire colours.
I don't think they intended you to delve there.
However, if you have the 4 wires off the fan switch it should cause no harm to dab the power on to each of the other three wires in turn - that's all the switch would do. One of the wires is direct to the motor - for maximum speed (the other two are via dropper resistors for the slower speeds).
If there is no joy, the motor is open circuit, or has lost its earth connection - the earth being a black wire going GOK where.
