i have a 2005 ford explorer xlt. last weekend when i was driving a light came on and said "check charging system" i drove for about 10 minutes and the car died. i jumped the explorer and it was running. i began to drive again and i noticed that once i slowed down the battery level went down. i replaced the alternater and the battery. the explorer was running great until 6 days later wheni went to start it. it was dead. so once agian i jumped it. and some codes came up on the message center: D900, 9318, and 9352. i can not seem to find out what these codes are. the next morning it was dead again! i have also noticed that when i turn the dome light on the message center says "door ajar' i have checked all doors including the rear door and read glass. still nothing has changed. also if i leave the headlights in the auto position they do not turn off....when i turn my done light on and it says door ajar i can not lock or unlock the doors. this is very frustrating. if anyone has any answers or suggestions please let me know. thanks for all your help.
