I took my car into the shop for body work and noticed a couple weeks later that the horn doesn't work. I checked the fuses, they are fine. I'm thinking the shop disconnected the horn then forgot to reconnect. Is this something I can check/fix myself?
How do you re-connect the horn? on 2000 BMW 328i
Look and see if the horn has an electrical connection to it - there maybe a couple of different ones - one maybe for the alarm. If the wire was disconnected, it can be easily re-connected
Look for the disconnected wires up near the grill area. If you can't find them then take it back the shop and they will reconnect for you. These little things happen and I'm sure it was just an accident.
