The first thing to do is clean the contacts on the leading edge of the door and pillar as mentioned in most door threads. If that doesn't do it look at the lock button and see if it is being pulled down when you lock the front door. If not you will probably need a new solenoid or at least clean it.

Got to agree with William, it's either bad/dirty contacts on the pillar/door or thedoor lock motor has died and needs to be replaced.

Thanks for responding.

Before I start this new thread, I've read all previous threads related to the Sliding Door problem, and I've also cleaned all contacts on the pillar as well as the ones on the door.

So, you are saying that a bad door lock motor can cause the sliding door to open even when Front Doors are in the LOCKED position???

 

[Greg Stoddard]

Yeap. The front doors lock status has nothing to do with the operation of the sliding doors. If the door lock solenoid in the rear door doesn't lock then the door is unlocked and when you hit the button it will open. You'll notice with the other door that even with it locked you can hit the open button for the door and hear the door start to try moving and beep as it sees that the door is locked.
