Alarm stopped working on 01 Yukon SLE. Not sure if its factory. It has shock sensor (could be aftermarket ) and valet mode. The fob locks/unlocks doors but no sound and led doesnt come on. Wiring looks like it goes to ecm. When you lock doors with interior button and doors open. It'll beep three times and lock when you shut the door. (Used to !). I recently had lower dash apart to fix the tow/haul broken wires and noticed the led indicator/ button wires had damaged insulation. I checked fuses but am stumped. Can this be reset with key in door lock or some other way? Didnt see any fuses for alarm. Ideas? Thanks
