OK, i think its because i took it to GM and they installed some recall thing for the ignition....i really wasnt listening.

But, for 2 days, my alarm siren has been going off. Might sound like a big deal, but its really really quiet, I only noticed when i opened the hood. I cant get it to shut off no matter what (besides pullin the fuse).

I have a siren on the inside of the car, and always have...that one seems to be functioning as it always did. It chirps normally. I cant get the big one under the hood to do anything....except for keep doin its thing(quietly)
