2002 Chevy Trailblazer LS alarm not working

Asked by: 23 views Chassi Question

I am trying to figure out why the alarm wont work because usually when you unlock the door from the inside after locking it the alarm goes off but that doesn’t seem to be happening. I also am trying to figure out how to make the horn chirp and the lights flash when locking it

    The alarm “ecu” probably thinks one door is open, what if you set the roof lights to light up when you open a door, is the roof lights ON all the time then? 🙂

    See 2-16 for some more information 🙂
