I have a 1998 Mazda MPV with an Autopage 700LCD alarm. All of the sudden the Auto door locks stop controling the driver side door.  It will lock all the doors when I arm the alarm.  But it will unlock all the door except for the drivers side when I disarm the alarm. What seems to be the problem?

Does the lock switch still work all the doors including the driver's door ?

Yes, when I arm the alarm it will lock all the doors.  But when I disarm the alarm it unlocks all the doors except the drivers side.

Velocity Motors, I just wanted to clearify your question.  If I do not use the alarm and just push the drivers side lock down, it will lock all the doors.  And if I pull the drivers side doorlock up, it will unlock all the doors. So, it doesnt' seem to be something with the doorlocks.  It seems to be something with the alarm.

Sounds like you have a central door lock system. Here is the wiring information for the van, you will need to go into the alarm CPU harness and test the wires going to the door lock wires:

|       POWER LOCK|gray                |-  |DKP or timer below AC blower|
|     POWER UNLOCK|lt. green           |-  |DKP or timer below AC blower

You will need to use a ground wire to toggle the lock wires and see if they still only do all doors except the driver's door.

All of the sudden it works now.  There must be a loose wire somewhere.  Thanks.
