I just purchased a 1998 Grand Cherokee Limited. Driving home, the
Drivers door ajar display was flashing on and off, and the dome lights would come on as well. I made sure the door was closed all the way, but it still does it.

Also, when I use the key fob to lock the doors, the horn 'chime' starts to sound. I imagine it is related to the door ajar sensor.

Any ideas? Thanks.
