I had auto lights and wipers on my problematic Focus 2.0TDCi Ghia.
I HATED THEM!!!!
- I hated the fact that whenever you started the car (from inside the garage) the headlights came on whilst starting and the wipers gave one sweep.
Hated the fact that the car was trying to start with the headlights on - not too good for the battery me thinks.
Also that single wiper sweep on start up was a pain in the a*s, especially when the car had been washed and polished, only for the wipers to sweep a nice mess over the screen!
Dont know if the Fiesta setup is the same, but I turned the features off on my Focus, I hated them......
Anyway, thats just me......
