2005 4.4 BMW X5 won't start
I need help. Had the battery, starter and alternator checked and all were good. Battery was at 12.5 volts. When I get in the car in the morning it's completely dead. No alarm or light no click. My ac stopped blowing cold air as well and my remote key fob stopped working. Does the key fob have anything to do with the car not starting. I tried reprogramming the key but no results. Do I need to change the battery in the key fob as well. Need help asap. Another thing my sleep mode is working fine and the alarm light is blinking correctly. Any assistance is appreciated.
