I am hoping someone can give me feedback. For last couple of weeks either when I go to get in my blazer there is a chime going off inside (no key in ignition). it will go for a few seconds and then stop and sometimes starts again. it seems to be very random as sometimes it happens after I've driven and turn off the ignition. Today -- I noticed the dash lights (not warning lights) flash, with the chime as well as the turn signal lights flash outside. Weird. I have an 05 blazer. Any feedback would be appreciated.
