Door Lock Actuators

[Marc Haibeck]

If necessary replace the battery and turn the PKE off by holding the door button for over two seconds or until you hear the locks cycle as a confirmation that the command was received.

If the battery is at 3.0 volts or more it's okay.

The door switch should not have a hair trigger. The switch should be adjusted so that the door moves back about 1/16" before turning on the interior lights.

If the pin at the tip of the switch needs to extend out more, pull the pin out and shim it with washers.

Turn the PKE system off and see if the door lock activity stops. If so, there is a problem with a door switch.

Oh! I wonder if this is why my PKE system seems to be going a little looney. With the doors open or shut and the key in the ignition the locks randomly and continuously unlock themselves even if already unlocked.

This seven-year-old nugget of info may have steered me into a good direction to investigate.

This URL may also be helpful for anyone needing PKE commands.

Not really knowing what your car is doing, door lock actuators being actuated while driving can be caused by faulty door light switch. My 94 was doing this and I tracked it down to faulty door light switch. These switches are self adjusting with plunger. As they age, plunder starts to permanently shorten itself to a point where the car starts to think you have opened and shut the door. With key in ignition, shutting of the door will unlock both doors. Door lights will flicker when this happens also.
