I installed the GMCHIME interface for my 04 Silverado to accept an Alpine cda-9833 hu and it all works except for the delayed locking of my doors. It is suppose to chime 3 times when you hit the door locks and then lock after about 10 seconds, but it starts chiming and doesnt stop unless you put the key in and turn the ignition to the on position. Anybody know of this situation?
