If a light-fan switch worked as one switch up turns on the lights and the other down turns on the fan then why would the fan switch suddenly reverse so up is on?

Sounds like someone has tinkered with 3-way switches (used to control one light from 2 switches).

Try bypassing the reverse light switch that plugs into the transmission. If your reverse lights come on, voila! Problem solved. Buy a new switch.

There is a backup switch in the gearbox. When you shift into reverse, the gear box switch contacts the switch and lights the white reverse lights. If you find that the reverse lights don't work it could be that the switch is not being triggered by the mechanism inside the gearbox. This is providing that everything else is working; wiring,bulbs,etc.

Both a stuck reverse switch and shorted wiring can be causes for reverse lights to stay on. Under normal circumstances, the reverse lights turn off as soon as the vehicle is shifted out of reverse.

Either the reverse switch is defective or out of adjustment.

The reverse lights switch on a Ford Fiesta is found on the transmission. The switch can be seen from underneath the car.
