LOCKS NO LONGER WORK

1994 Nissan Pathfinder

Electrical problem
1994 Nissan Pathfinder 6 cyl Two Wheel Drive Automatic 94,000 miles

When I had my mechanic dismantle an alarm system put in by the former owners, the lock system went gaput. At first I got locked out of the truck and couldn't get in and then I got locked in and couldn't get out. (All locks) (The key would not always work) Now after two trips to the mechanic and after he dismantled the auto lock system and removed the door to correct the problem, the driver's side still will not open and the battery keeps having to be jumped. (New battery)

Also, the windows will not work.

Hello .. thanks for the donation .. much appreciated

You will have to ask your tech to do a PIN test of the VSS module to locate any faults on the wiring or module .. hope this helps .. let me know

DESCRIPTION & OPERATION

NOTE:Any time the system is programmed all transmitters to be used should be re-entered to avoid unintentional "bumping".

All Vehicle Security System Transmitters are programmed for an electric module at the factory and installed as a set at the Port. Therefore, when a vehicle arrives with a Port installed Vehicle Security System the remote transmitters must stay in the vehicle or securely attached to the keys until delivery to the customer to avoid separating the transmitters from their corresponding electronic module in the vehicle.
The Nissan system can learn up to 4 different transmitters, (codes). If a fifth transmitter is entered the first transmitter is "bumped out" as only the last 4 to be entered are remembered. If only 2 transmitters are used they should each be entered twice so that all 4 memory locations are filled. The system will remember the transmitter codes even if the vehicle battery is disconnected so that routine reprogramming is not necessary.
Electric actuators are used to lock or unlock doors. Actuator assembly has switches to limit actuator travel. A timer limits current "on time" required to operate electric door actuator.

DOOR LOCK ACTUATOR TEST
Disconnect door lock actuator connector. Apply battery voltage to door lock actuator. If door lock actuator does not operate, reverse battery leads. Door lock actuator should now work.
Reverse battery leads and door lock actuator should reverse direction. If door lock actuator does not work as described, replace door lock actuator.

check the circuit breaker and the window amplifier for the window fault ..
