A switch is a mechanical device for controlling the flow of current in a circuit, switching the current either on or off.
A fuse is designed to melt safely when a current exceeding its maximum current rating passes through it, thus protecting the service wiring supplying power to the connected load.
For example, if the connected load develops a fault which causes a high short-circuit current to flow in the service wires, if there's no fuse to break the flow of current then the service wires would get very hot and could cause a home fire.
check fuses/relays; I'm pretty sure the 190e has one fuse the 2 rear windows

Start by checking your fuses. Then bulbs. Then switches in that order.
The 1995 BMW 525 fuse box layout consists of two columns of fuses and one column of relay switches. The fuse columns will have 10 fuses each.
The layout for your 1990 Nissan fuse panel will consist of two columns of fuses. There will be 10 fuses in each column. The third column is reserved for relay switches.
