Q: Smell of burning wires and smoke in interior on 1990 BMW 535i

I had smoke inside while driving and a very bad smell of burning wires. After shutting down for a few hours and running it again, there is no more smoke but still some continuing smell of wire burning. The heater fan no longer works.

Any ideas on where to start looking?
