I replaced my 2003 Escalade Ext factory alarm with a Clifford Matrix w/ remote start. In the beginiing the alarm workd fine. After a couple of months I ran into a problem with my battery being drained. I took it back and got it reinstalled with a different passlock module. That seemed to work fine for about a year. The other day I got off of work and the truck wouldn't start battery dead. Took it to shop and had electrical system checked, nothing there. Alternator, charging system ok. Nothing drawing a current. My question, is there something associated with the remote start that is staying on and running my battery down? I really would like to get to the bottom of this!!!!!!
