There will be a small lock tab on the switch plug. Some need to be pushedin, some need to be pried out, and I have on some Japanese connectors you squeeze on the sides to release. A small flat screwdriver is the best tool for releasing lock tabs.
Possible causes are a fulty horn relay, faulty horn switch (probably part of the steering wheel SRS module), or a short circuit between the horn relay & horn switch. Quickest temporary fix is to remove the horn relay, but as a horn is part of the required safety equipment on automobiles you need to find the source of the problem & fix it asap.
Need to clarify what you are asking. The Horn Relay is inside the relay/fuse box behind the battery. The Horn Switch is located in the air bag in front of the steering wheel. You must replace the air bag module to replace the Horn Switch. The Horn switch grounds the relay which then powers the horns.
The 1991 Honda Accord horn relay switch can be found mounted to the radiator. The horn relay switch will be on the right hand side of the radiator housing.
Basically, a "relay" is a switch. When you push the horn button you're triggering the relay which in turn feeds power to the horn.
Typically, that problem would only be caused by a faulty horn relay or a damaged horn contact switch inside the steering column. A frayed wire that rubs on a metal part of the vehicle. Since the relay is the easiest part to test, remove the relay and replace it with a similar relay FOR TEST PURPOSES ONLY. If the horn works properly with a replacement relay, put the relay you used for testing back and purchase a new horn relay. If the test relay left the horn ON, you probably have a damaged horn contact switch, in which you will need to replace the faulty component.
