The shop tested the battery and alternator and said the alternator is dead.

My 2095 Mercury mariner premier doors used to lock when ignition turned on and unlock when ignition turned off. They stopped. How do I fix?

At any given time, while driving, the message center beeps and says rear passenger door ajar. This causes the interior lights to flash. The door is closed and locked while i'm driving. I can't lock the car when it's parked, the alarm will sound at any unpredictable time, so I have to leave my car unlocked.

Thought 4wd was on all the time can't find problem with Abe and 4wd service lights on any problem to keep driving
