92 Pathfinder power locks broken

My Daughter has a 92 Nissan Pathfinder with manual transmission. The problem is the power locks. They are in the unlock position but now the locks will not lock and the vehicle cannot be secured. I have looked through the Chiltons Manual for information on how to troubleshoot this and possibly repair it but cannot find any info on it. Perhaps someone might be able to give me some direction on finding this information or how to repair this issue? I would be grateful. :confused:

I have a 1992 Nissan Pathfinder SE v6. The electrial system is having problems and I wanted to know if anyone has a solution. The Power- door locks do not work. The Fuel guage and Coolant tempature guage do not work. The problem was intermittent but now permanent. I thought it was a short. Do anyone have a schematic for this vehicle. I am looking for the location of the cooresponsing fuses - or relays - none of the three systems with problems are listed to a fuse or relay.

just recieved the keyless remote, programming went fine but still having trouble with the locks. I've tracked it down to a connection in the rear of the vehicle. It's inside the trim on th drivers side about 4 inches in front of the access panel for the lights. If I play with this connection, I can get the locks to work. does any one have a scematic or knows what this connection is?

is what you are talking about called a "door lock timer"?
I'm also in need of the wiring diagrams :1zhelp:

replaced the door lock timer and the power locks are working like new again :grinyes:
