Hello, I have a 1999 Grand Prix GT and it has started to unlock itself randomly while I am driving and after car is shut off. Both doors will unlock and the interior lights come on and dim every few minutes when key out of ignition. I have removed fuse from locks saving actuators though still hear relay engaging every 30 seconds or so. Further I have found hitting lock once on key FOB after key out of ignition stops lights from cycling on and off. Please advise after review. Thank you.
