Turn signals rapidly blink and click on dashboard, and they do not work. When I turn the car off -- the blinking and clicking continue for approximately 15 minutes. This is while keys are in my hand and not in the ignition. Also, upon start up, the trunk pops open. The door locks do not work. Emergency lights are OK. Interior dashboard lights get dim when I turn headlights on. Headlights fine from outside view. But dashboard lights go dim. Headlights off, dashboard lights brighter. Fuses OK - not blown. Removed battery. Cleaned terminals. Replaced battery. Then radio would not work. Reset radio. Seemed problem was fixed. Not for long. Trunk popped open and all issues returned. What is going on with my car??

Faulty Body Control Module (BCM)?
