Door locking not working

1997 Maxima SE, Power everything.
It began with the passenger door not locking with the other doors (the knob shows almost locked). To lock it, it had to be "manually" locked. Now, it won't lock or unlock, with power or manually. Can "unlock" with manual lock knob but the door stays locked, and now we can't open it because it stays perpetually locked! Felt the lock mechanism move up and down with slim-jim so I think the rod from the knob to the pivot point is working, from there down to the lock, I can't tell. NOW, even when the power locks are used, the knobs show "locked", the "locking noise" is made, but the driver's door will still open anyway; but not the passenger's! In case it was a power problem, which I think it is (tell you why in a sec), I removed all "battery" fuses, since none said they were for the door locks, but none killed the power to the locks. I think it is a power problem because I noticed that when I lock the driver's door with the knob, it stays in the "locking" mode for a second or two, instead of just locking and releasing (like you were holding down the lock button too long and it was still getting power). Long story but I tried to pre-answer as much as I could! P.S. - I made a donation, as anyone who uses you should! I didn't know you guys were here and even if you can't fix this problem, there have been many more times I could have used you! This is an excellent idea!

HAHA! No, forgot about the ones under the hood! Thanks, I'll try that tonight - at least it will let me know if it is a power problem or not. Thanks!

OK, here is where I am. I pulled the fuse and the power was cut for the locks. The passenger's door is still locked, the driver's door is still unlocked, no matter what you do with the knobs. Putting the power back to the locks does this: Doors "lock" but are still in the same configuration as stated above (the rear doors seem to be working as they are supposed to). When I unlock the doors, with the remote, the doors unlock but then quickly relock, although they aren't really locking and unlocking! (Except for the rear doors!) I am about ready to pry the freakin' passenger's door open just so I win! I don't mind bringing it to a mechanic but I should be able to do what they would have to do to get the door open! As stated in my original post, a "slim-jim" doesn't do it, the mechanism (at the pivot point) is moving but doesn't affect the door. I pulled the driver's door panel off and played with it, the door lock seems to be working fine but, of course, it is not! All the rods move when moved but the door is not locked.

The windows and door locks do not work on all doors and windows the sunroof and the automatic seat still work the fuses have been checked and are all okay please help point me in the right direction.

Electrical problem
1995 Nissan Maxima Automatic 130000 miles

The power locks, power windows, radio, and the lights in the visors stopped working before replacing the alternator and battery. What else could it be?

Start with the interior fuses under the dash, then get a book and look for the fusible links

Hi,
I have a 1995 Nissan Maxima base model, V6, with 150,000 miles. When someone shuts the passenger side front door, all other doors automatically lock except the front passengers side. It doesn't always happen, but most of the time that door is shut, it will lock all others. Sometimes when I push up the switch (on drivers side door control panel) to unlock the doors from the inside of the car, they all automatically lock right back. I can do it again to unlock and then they will usually stay inlocked. I can also double turn the key to unlock all doors (from the outside of the car) and sometimes they will all lock right back. Do you have any ideas what might be wrong?
Thank you

I have a 98 Nissan Maxima SE. I am experiencing the same exact problem as you, except I have the problem whenever someone shuts the front driver side door. Also whenever I try to lock the locks, they lock for half a second and unlock bac. However, it only happens to me during the winter time (in cold temperatures). Every late fall, the problem comes back and stays until early spring. I don't know what the solution is either.

Hi, thanks for the reply. I haven't fixed my problem yet. MY husband took the door panel off and unplugged and re-plugged everthing back in. It seemed to help for a few days, but it started back. I dread taking it to the dealer because I know it will cost a small fortune to get it fixed. Good luck to you.

My 1993 Nissan Maxima GXE criuse control will no longer function (on same relay as horn & the horn does work). The automatic door locks worked intermittently and now doesn't work at all either. The car (256k miles) has automatic trans & works very well except for these 2 issues. Any suggestions?

I bought my Maxima recently and the power locks were out when I purchased it. So I took it to a car audio and alarm shop and they checked it out, but the only thing they checked was the driver side master switch and the fuses and I already knew that wasn't the problem. Also when I push the power lock switch there's a clicking noise coming from underneath the steering wheel, it some sort of relay that says " power door lock timer" it is a little black box. But I went to a junk yard to replace the power door lock timer and it did the same clicking sound. Also my car has a keypad right below the outside handle on the driver and passenger side that has a code to lock and unlock your car without the key, so I don't know if maybe that has something to do with it because it doesn't work either. If anyone has an idea I would appreciate any type of feedback. I've heard anywhere from the door lock motor to a relay or even some sort of fuse.

I m having the same problem. We had to change the ignition switch it came with new key. Does that have something to do with it. Also master switch works just wont lock from the master. Everything else works like windows.
