Yukon Horn chirps when key is turned on

[ewisman]

On my 2003 YukonXL, when I turn the ignition key to on, the horn chips three time very rapidly. There are no warning lights displayed. I tried reprogramming the remote key fobs but that did not remedy. Any words of wisdon out there. Thanks

Do you know the history of your Yukon? It may have an aftermarket alarm or remote start hidden on it....from a Dealer or a previous owner...

I purchased this Yukon one month ago from a dealer so I don't know the original owner. I have no idea if the previous owner installed a remote start. The chirping began yesterday.

well after reading you question, I went looking. There appears to be some typy of small receiver, about 1 inch square, installed (aftermarket) below the steering column. I did the typical newbee attempt at fixing by jiggling the wires. To my surprise, it worked. Horn chirping is gone. My question now is, can I just disconnect that devise, or if I wanted to use it, is there some way to get a remote device to activate it. Thanks for your help.

See if you can a name on the box and a model number- and see if there are any switches or lights attached. This will help us identify it...
