HELP!! Keyless entry and horn problem!!

[sethsperlik]

The other day I went to lock my Yukon and the second time I pressed the lock button on the fob, instead of tapping the horn it stayed on. Is there another relay for the horn in the cab? I tested the one under the hood by switching it with another relay but it still stays on until you pull the relay. But, when you put it back in it stays on.

Thanks in advance,
Seth

The relays for lock/unlock are in the cab... Not sure that that helps. If it's an 03+ you could just change it to not honk when you lock it, if you don't care about it honking.

The problem was in the key fob receiver. Whatever controls how long the horn honks when you press the lock button twice is broken.
