My brand new Saga came with a malfunctioning air-cond -- blowing only hot air.

The SA led me to a service centre, where the mechanic opened the fuse box under the bonnet and pulled out 2 transistor-looking gizmos. The way he pulled at it looked like the whole part was gonna be ripped out. Then he just swapped their positions in the fuse box and the air-cond started blowing cold air. :\
