Hi i have a 2000 jeep Grand Cherokee with a factury alarm...I've never had any problems with it until last night....When i set my alarm now everything locks but the HATCH??But more importantly my Jeep won't start http://forum.sounddomain.com/images/graemlins/default/mad.gif..I've of a auto shut off for the alarm could this be the problem?I've even trying to lock it manually via the KEY on drivers side door...Also useing the key on the drivers side door..ONLY locks and unlocks the drivers door and not passengers etc. I heard it might be the rear lock motor might be bad??Can i test it..thank for any HELP...
