the only thing I think it could be is the ignition wire or accessory/blower wire. But I put a multimeter to the ignition wire and pressed the start button and no voltage was read through that wire (Both accessory/blower and ignition wire are connected at bcm, not ignition if that could make a difference?). Could the remote start module just be bad? This is puzzeling me. The starter wire is not connected because I read that it doesn't need to be wired for the cobalts.
