Sliding door locks
When I use the lock switches on the driver-side and passenger-side doors, they do not unlock nor lock the sliding doors. The key fob does not work on the sliding doors, either.
UPDATE: Periodically the automatic locks on the sliding door will work with the key fob and the front switches. Usually this is in cold weather. When the weather warms up, they stop working and I have to unlock them manually.
You need to replace the door-lock actuator motors.They lock and unlock the doors. O'REILLY has a competitive price on this. Auto Zone tends to be a little higher.
The electronic actuator motors/really a push pull wrapped magnet assembly are probably done.They are cheeply available at any local auto supply.Just be careful removing the door panel.
You have a bad connection somewhere. Check the door jam first before removing and replacing $100 in parts.
I agree with budman. The problem with mine I believe to be in the connection at the door jam. Clean the terminals and see if that cures your problem. It's funny to me that my problem happened in COLD weather instead of warm weather. They would lock up in the winter then as the weather warmed they start working again.
Clean the terminals on the door too.... !!
