My power lumbar seems to have stopped working recently, I checked the fuses (i think, #8 and #11 under the dash by the drivers left foot, 30amp, purple topped weird looking fuse) Found something that looks like a fuse under the drivers seat, but it's just some kind of junction box/link. Am I missing anything else?
I think the wires are ok. I traced them under the seat (white with black stripe) and don't see an issue or another fuse.
Thanks everyone for the help, the lumbar was killing me as someone else had used my car and cranked up the lumbar. I usually have it at zero so I need to do something. Took matters into my own hands (no warranty left on my car) and opened the back of the seat to gain access. There is a black elastic worked around the seat springs that holds the bottom 4 inch flap, just unwind it for access to the upholstery "hog rings" and cut those (3), then undo the 2 zippers and you are there. My car has factory leather, so i'm not sure if it's the same on the fabric seats. I could hear the motor click slightly when the switch was depressed, so I figured it had power, I gave it a few whacks with some pliers and it worked! Looks like it's a power window motor that runs the mechanics of the lumbar. I used zip ties to replace the hog rings and put it back together. I couldn't find any pics of what the power lumbar system looked like anywhere, so I thought I would add some to the fix description.
My lumbar is air pressure, and I see air hoses in the second picture, but I would think that a window motor would be good for moving the seat in the many directions it moves, not being a wise guy just wondering.
Those aren't air hoses, it's a type of rubber hose used to attach the foam seat cushion. If you look closely you can see it flares out after the hog ring. I'll attach a better picture.
