I have no idea what year the donor door is from =/ i can live with doors not locking together- but what i just found out is that this is also tied in with the security system. so if i just close the door shut without locking it, the alarm activates and goes off if i open the door. so basically i have to lock the car every time i step out, or deactivate the damn alarm with the trunk key. what a pain this is becoming. any way i can easily disable the security feature without pulling out that 10amp fuse? thanks again.
