Hello

Hello.I'm not sure if my previous question was submitted or not but I will send it again just in case. I am having an electrical issue with my mountaineer. I think they are all related somehow but i'll give you a list of what's happening:

1. When locking the doors (and all are shut) horn chirps twice indicating something is open.
2. Exterior mirror lamps and interior lamps stay on for 10 or so minutes after the door is locked. Once they shut off, if I use the keyless entry code. The alarm goes off.

3. The lock button on the drivers door will only work if the key is in the ignition and the door is closed.

4. Also, when I take the key out and turn the car off without opening the door, the stereo shuts off and I believe it's supposed to stay on.

Do you think this could be a short somewhere? Perhaps in the driver's door jam? Or a fuse issue? I feel like it's all related to one thing and narrowing that down to that one thing is what I need help with! Thank you!
