The car horn sits at the front of your car where grime, dust, oils, and other small particles can build up over time. This can lead to build up or corrosion on the connector, resulting in poor conductivity. Sometimes, all you need to do is clean the wire connector and reattach it (good ol’ WD-40 will do thee trick).
Can you drive without a working horn? Your horn is a safety feature, so it stands to reason that it should be in good working condition. Most problems with your horn would only result in a minor fault on your MOT, but if your horn is not working at all, your vehicle will be deemed unroadworthy.

Why is my horn blowing fuses?
if it only blows fuses when the horns are plugged in, then the horn itself has shorted internally and has to be replaced. if you have a ground problem, the horn(s) will either not work at all (broken wire) or be blowing constantly (shorted wire).
If you remove the horn fuse and don’t replace it, that circuit will be “broken,” so the horn won’t work. If you removed the fuse for the radio, the radio wouldn’t work. If you removed a fuse or breaker for the ignition or fuel injection systems, the car wouldn’t start (assuming it’s a gasoline-powered vehicle).
