My B-pillar seat belt adjuster does not move when the seat goes back and forth. For those not familiar, it's supposed to raise automatically when the seat is moved backwards to accommodate a taller driver and vice-versa.

The other side works as expected.

(pic from the internet):




I went to my dealership looking for a motor or something that may need to be replaced, but they weren't able to easily see what controls it in the electronic parts catalog. There are a bunch of pulleys there to facilitate the seat belt attachment point going up and down.

Any idea what's going on?

There is a cable which is attached to the seat.
specifically the back part of the bottom rail. Sometimes it gets disconnected.

Awesome! Thanks!

Well that explains why there isn't a code being thrown.

Any clue as to where the cable attached? I had the B-piller apart when I was replacing the sunroof (had to remove the B-pillar trim to drop the head liner), and I didn't notice anything that was disconnected.

Is the connection near the seat bottom?

You were absolutely right. Thanks for teaching me how to do it.

Push the seat all the way forward and as high as it will go. This will give you access to see and fix the item. It's a "claw" that attached to the seat rail. When the seat moves, the cord is pulled and the seat belt adjuster moves.

Here is my passenger side that's working correctly. It's a blurry pic, but you can see two weird things connected. The arrow points to a cable that goes into the B-pillar.




Here is the driver side...see that it's off:



Push up on the seat belt adjuster (it's spring loaded) on the B-pillar and it will release enough slack for you to inspect the "claw". If you don't push up on it, you won't have any slack to pull it out:



Note that it DOES NOT just snap on in the direction that it's designed to be at rest laying along the seat rail. You must insert it PERPENDICULAR to the seat rail then twist it into it's resting position.

My first two tests failed. The claw jumped off both times during testing. I had to use pliers to gently squeeze the two pairs of prongs together as I think they stretched over time. The pic above shows how it looked after I squeezed them together. Notice how wide they were before.

Third time held. Let's hope it stays.

It does??? I didn't know this. I've never been short.

This drove me nuts as the low seat belt was the very first thing I noticed when I test drove the car. I was searching all over for the button.

Apparently there is an ideal place for the seat belt height in relation to torso height. That torso height is estimated based on how far the seat base is from the steering wheel.

It will move like this:


It's subtle, but it's happening.

Also, most cars have a manual adjuster here. Like this:



Some nicer cars have a button for it:
