1999 grand cherokee, chime 3 time after starting.
I recently bought a used 99 Grand Cherokee for my son. We have had quite a few problems. But the latest one has me stumped. After starting the check engine light and alarm turn off as usual. There are no warning lights on the dash everything seems normal except the car chimes 3 times. I noticed if you start with the driver door open it does not chime. I looked through the owners manual and found nothing on this. Any help out there would be appreciated.
