I have been having trouble with my keyless remotes & panic botton working to unlock/lock doors. They started not working from more than 10 ft away, then it got down to I had to have the remote right next to the drivers window for the remote to work. Then they just stopped all together. During this time my Navigation stoped working twice to where I had to reenter the code. I have also had other warning lights come on and go off. Can anyone tell me all the things controled by the AAM. Is there any risk of the car failing to run at all if I do not have it repaired right away?
