A couple of days ago I unlocked vehicle, started and alarm horn constantly blows. It will blow until I stop vehicle and then lock and unlock doors several times. Today i continue to troubleshoot the issue to find that the battery was dead with just a clicking starter motor. Jumped it off and again the alarm horn blowing. I removed the anti theft 20a fuse and still blows. I too disconnected the hood anti theft switch and still blows. Any thoughts or ideas to chase, I do not have the skills or expertise with checking volts and signals. So I am hoping that this rings a bell with someone. Thanks in advance to all.
