    No, I am not good with that stuff. Extended warranty to the rescue!!!!! My trusted mechanic is the backup if I ever get into a bind and don't have the time to drop the SRX off at the dealership.

    Re: No Lumbar, can be a easy fix!

    I'm glad to learn of this... My Lumbar has stopped working twice, and both times the dealer replaced something.

    I thought it odd that it broke, considering I only weigh 165, and I never move it except by accident.

    this will be handy to know, once the warenty is gone.

    Re: No Lumbar, can be a easy fix!

    What I am thinking is the motor continues to turn till it reaches the end and twists off the head, are there an GM mechanics on this forum that can explain the sync of this system. Is it suppose to have a torque limit so it does not break off the head?

    yes, but the teeth on the motor end would make it expensive to make, I am sure the thread and a dimple indention on the head could be easy for him

    Re: No Lumbar, can be a easy fix!

    I did not give up yet, I super glued the head again, this time I drilled a hole before the head to stop before it gets to the head, the pin should take the force,which may be what breaks the head when glued, worth a try since they do not sell the plastic screw

    I was able to repair mine even easier than that, dropped it off at the dealer, picked it up fixed

    If it breaks again I will give your solution a try.

    Re: Lumbar repair, quick and permanent fix using a metal pivot!

    I have come up with a fast, easy, and permanent fix to the broken plastic lumbar positioning screw.

    Parts: 1/4" x 1" bolt, nut and washer.
    Time: after removal, abut 10 min.

    1) Take out the lumbar assembly. (see above posts)
    2) Cut the plastic tie and remove the motor, screw and broken screw end.
    3) Cut off the white plastic nipple that acts as the pivot for the screw. I used a box cutter.
    4) Drill out a 1/4" hole in the same spot as the nipple was.
    5) Insert a 1" x 1/4" bolt to act as a new pivot for the screw. (the screw is hollow, so this is an easy fit)
    6) Tighten up the nut and bolt, then place the washer on the bolt (past the nut) to act as a smoother screw stop.
    7) Wrestle the screw / motor assembly back into the housing
    8) Put on a new tie.
    9) I drilled out two additional holes for a smaller tie near the top of the motor, as I didn't trust the clip, which was distorted after the screw broke.

    Re: No Lumbar, can be a easy fix!

    AN FYI:
    I can get my hands on all sorts of lumbar motors, screws, plugs, etc. However; I'm not too sure how many of the parts they have now will work with the SRX.
    But if anyone needs anything please take a clear picture of what you need and I will try to get it for you. You just pay shipping.

    Re: No Lumbar, can be a easy fix!

    Hi
    So if I understand the treaded part on the new bolt goes insidee the lumbar screw. I assume the bolt is a tight fit in the lumbar screw? whats to prevent the lumbar screw from just spining on the new bolt? I think these motors have a high torque, hence why the breaking of the srew heads, seems like it keeps trying to turn even when it hits the dead spot. By the way mine is still holding up from the mod above, the pin stop. but I could use a couple of lumbar screws if you have them. PM me and I can send my address.

    Re: No Lumbar, can be a easy fix!

    I need a picture of what you're talking about.
    This is what I have as of right now. I was trying to get one of the motors to work with my cutout.
    Sorry for blurry pic, but you get the idea.
