I have been having trouble with getting my aspen to start. from time to time it will just not crank. sometimes i can get my key fob to start but that has been not working lately. i have noticed that while driving my security light will come on and make a chime that is when i know i am going to have trouble over the next couple of days. also i have noticed that sometimes when this happens one of my inerior light will start flashing. could this be due to the BCM "body control module".

 

I am having the same problem with my 2007 Aspen. Did you ever figure out what was causing your problem?
