How much does a relay switch cost for a 1999 Honda accord?
You have to be more specific on what kind of relay.also prices vary from store to store.
Mine is a 1999 Accord V6 coupe and I don't think there's a horn fuse. There is a horn relay under the hood in the back left in a black plastic box. On mine there are 3 identical relays (2 for headlights and 1 for the horn). If the 4-cylinder has the same arrangement as the V6 you could switch the relays to see if that was the problem.
