I have an A4 1996 Audi.

My high beams and low beams are not working but my parking lights are. My air conditioning is also not working, no lights show up on it and no air comes out.

I checked the fuse and its all good. Any ideas on whats wrong with it?

 

Use the search feature and try the terms "combination switch low beams" or "combi switch low beams" and you'll likely find everything you need.

For the climate control, you may simply have a dead CC unit.
