Hyundai Elentra Door Lock Problem

I Installed an alarm system in my girlfriend's Hyundai Elentra about a year ago. Everything was working fine until a few weeks ago when the door locks stopped working. The drivers door works fine since I installed an acutator there origianlly and it continues to work. One of the features of the vehicle was that when the drivers door is locked or unlocked all the doors lock or unlock. Does anyone have any idea how they do this? I assume there is some kind of signal being sent to the factory actuators in the other doors by the drivers door(which makes the exclusion of a lock/unlock switch inside the car somewhat puzzling if the actuators are there). Is it possible that adding an actuator to the drivers door has broken this mechanism? I would assume not since all I am doing is locking or unlocking the door manually with the use of the actuator. Of course a trip to the dealer met with a 'its the alarm' response as soon as they saw some non-factory wiring. I am tempted to remove the alarm in order to force the dealer to make the repair but I don't want it to break again once I re-install the alarm. Does anyone know what wires are being used in the factory setup to lock/unlock the other (non-driver side) doors? Maybe I can just use the lock/unlock pulse from the alarm on these wires to make the other doors work again. Thanks, Alex D.

It's a 2001 Elantra (spelled it wrong in the original post)

Turns out I found a great resource for Hyundai vehicles at Hyundai Web Tech it even has a link to a service bulletin that describes a possible cause of my problem (which the dealer never bothered to address because I had an aftermarket alarm in the car) and a solution to the problem which I will give a try this weekend. Does anyone know of any other car manufacturers that have websites like this available to the general public?

i I,m work for hyunday. I,m see every day elantra with doors lock module inside of drivers doors for lock/unlocks other doors. i tink your problem is switch in driver doors.

Thanks :) I'm going to check the connectors in the door this weekend. I'll be sure to check the switch as well. Alex D.
