Jeep Repair: 96 jeep GC security system not engaging, battery drains overnight, jeep grand cherokee laredo, grand cherokee laredo

Question
Hello and thank you in advance. My 1996 jeep grand cherokee Laredo 4.0 security system has stopped engaging and my battery is dead if not driven everyday. The key fob locks and unlocks all of the doors except passenger side door which works 1 time out of 10. So security system not working, passenger door not properly locking unlocking with key fob, and battery drains overnight. Please tell me how to fix. Thank you

Answer
Well there is noting I can tell u what to do here   Unless u want to just throw parts at this thing.  A scanner will need to be used to get into the alarm system and see what is setting it off  and go from there see if is a module issue  or a switch issue.
