On the first picture, the tab to unlock the door moves slightly but doesn't stay and the door stays locked. On the second picture, the unlock button on the remote doesn't work either. You can hear it working and the tab moves back but it doesn't stay, as in the third picture of the driver's side passenger sliding door, and the door remains locked. What you see in the third picture of the driver's side sliding door does not happen to the passenger side sliding door. I can see the red mark appear but then it hides back again like if something is blocking it from sliding all the way. At one time the open door icon on the cluster lights up red and a beeping sound starts meaning a door is ajar. When checking the passenger sliding door from the outside, the door has not locked entirely and will have to push it locked so the beeping sound terminates.
All the doors open by remote and manually but not the passenger sliding door.

Hello,

When these doors have a problem it is usually the motor and cable assembly which wear out. I would remove the door panel and use the diagrams below to check out the motor and replace it. Also please lube the door slides/pivots after replacing the the motor. Can you please shoot a quick video with your phone so we can see what's going on? That would be great. You can upload it here with your response. Check out the diagrams (below). Please let us know what you find.

You wouldn't happen to have photos of the inside panel of the passenger sliding door? The same diagrams you sent me but in color photos.

They don't have color images sorry about that, but I did find more repair information on how to take the door apart. Look at the diagrams to help you if you get stuck in the repair. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

Below is a picture of the driver side passenger sliding door lock, unlock button electronics. My passenger sliding door has locked and can't open it from the inside or outside of the vehicle. The silver coil around the knob could be the reason. What do you think.

It is difficult to see from the picture but is the spring broken? Can you get closer shot?

Oh okay sorry. The picture is from the right (driver's) side passenger sliding door. I couldn't get a straight picture from the defective door since I can only get the cover a quarter opened since I can't get to the screws which are located on the side. The red outline is on the good side and I believe that silver coil going around that knob is misaligned. Can I remove that coil without messing up anything else?

It's hard to say. That service the unit as a whole (replace the part). Can you please shoot a quick video with your phone so we can see what's going on? That would be great. You can upload it here with your response.

I finally fixed the locked door. As in the picture below, the problem was on the 'child lock lever'. It's a long piece that goes all the way down on top of the 'lock/unlock lever'. You can't see it in the picture but inside the 'lock/unlock lever' is a spherical rod. The 'child lock lever' was keeping that rod from sliding up with the 'lock/unlock lever' for the door to open.
The idea I came up with is to disconnect the 'outside door handle lever', take the 'child lock lever' piece and push it in so it would be against 'aluminum #1', it wasn't hitting it before. This cleared the way for the rod inside the 'child lock lever' to go up and open the door. Then I just connected the 'outside door handle lever' piece back. Now everything works perfectly.
