Device malfunction

Hi, so a mechanic had moved my headlights and stripped a wire that was connected to my head light and left the bare wire showing. He put headlight back and the wire touched metal and shorted a fuse out and when that happened my headlights stopped working and the dash says device malfunction with a picture of a car with an arrow pointing up in the middle of the car. Then the mechanic went to a fuse on the passenger side under the hood fuse box and he replaced the 40 fuse and when that happened my headlights started to work, but it still said device malfunction. Then I was driving went over a speed bump and headlights went out again. It did this 3 to 4 times until I looked at the wires to my headlights and they were stripped showing copper wire exposed. So it kept shorting out that fuse, but if i'm correct the headlights don't have an actual fuse it has a electronic fuse and it consists of different wires and relays. Well I fixed the bare wiring from touching so the fuse never blew after that. But still said device malfunction so I changed the air compressor relay and still doesn't work but it sounds like the compressor kicks on but doesn't raise the car up or lower it when parked. When I changed one relay when I press the button to raise car it sounds like it is kicking on then stops and before I changed the relay it was really bouncy and now its not but still says device malfunction. Please help. I know there are two relays for the air suspension compressor. I only replaced one. Maybe if I replace the other one it will work?
