Lumbar supports not working?

[Honcho]

Hi. I’ve been playing around with the lumbar supports in my seats but the 4x way lumbar buttons only seem to adjust 2x ways - two of the buttons inflate the same spot, two of the buttons deflate the same spot. This is the same in both of my seats. Is this normal?

Same, why I ditched the stock seats.

I’ve noticed the same thing. I can inflate or deflate the lumbar support, but I can’t make it go up or down so it’s in the position where I actually want it.

Do we think this is a fault (ie. it should be able to go up and down) or it designed this way (I’m which case what’s the point of the four buttons)?

Hmmm, it seems the lumbar support is meant to be adjustable up and down according to the manual. Maybe another common fault?!

Ok. Took the seat back apart. There are two air bladders on top of each other so both inflation buttons will move out the same area which is pointless. I positioned one bladder upside down and higher up the seat (circled red) and put a plastic panel (not pictured) behind it just like the lower one (circled green). Now I have lumbar support adjustment in different areas!

To remove the seatback there are 2X torx screws under the logo and 1x inside the seat back recline lever. The rest is held on with clips.

Damn I feel like this needs a tutorial of it's own lol.
