Hi i have Cherokee sport 2001 and central door locks not working, at the same time all passenger windows cannot be open only i can open from driver side console. few days back all the door locks start

remove door panel and check linkages

(door lock actuator)all doors have one in them, they weeken, and sometimes work to open, and some times to lock, or not at all. only fix is to replace each of them as they go out, usually cost abt 20 to 40 bucks a piece

There is most likely a break in the connection on the passenger side wiring harness that runs thru the doors jam. Either a wire has broken or there is a bad connection at the module connector. This is a very common problem. Sometimes you can grab the harness, when the passenger door is open, an move it around and the door switch will start to work again. The best thing to do is pull off the panel and check the connection at the module window switch then proceed to the wires that are in the door jam, the ones that bend all the time when the door is opened and closed.

sounds like an open power or ground circuit on passenger side,since the door lock and the window,lost its functioning.Both switches would have to be bad at the same time,which is not probable, to be the fault. Unless there is a saftey lock out switch on the drivers panel,controling the passenger side door lock and window.

turn key twice when opening, ie turn right. once drivers door will unlock, turn twice passengers doors will unlock, and locking is turn anti clock wise once will lock all doors, turn twice will set door dead locks.dead locks will stop openand lock internal button working and handle from opening door. the same actions can be applied to the remote one press drivers door, two press passenger doors, press and hold unlock button for 5 seconds and rear window will open.

2006 Nissan Pathfinder rear passanger doors don't open unless opened from insinde handle first. Then will open all the time until central locking is used then same problem occurs

Lock and unlock both run off the same power supply...I'd be looking for a bad switch or a broken wire in the door harness where the wires go through the rubber boot between the door and pillar.

I have a 2003 chevy silverado and the passenger side power window does not lock or the window wont go down.

the main ground for the switch assembly is open somewhere.

Check the wiring between the drivers door and the A pillar(the body of the car). Sometimes the harness breaks from opening and closing the door.
