While I was driving today, my 2006 driver's seat lumbar support "popped", sunk in and now the turn knob does absolutely nothing (just spins). Has anyone else had this issue and is there a fix?

i have the same yr and model, mine popped on me with in a month of having it cranked up as tense as it can go. I believe the only fix is to take the seat apart i need to do some more reasearch on it myself to get it fixed.

I just got quoted for it today, they told me its a lumbar support actuator. The estimate for this would be $259 + tax. I didnt get it fixed

bump?.. Add another '06 to the list. On a scale of 1 to 10 how aggravating is it to take the top portion of the material off the seat, fix the support and put back together?

Me too... it happened two years ago. I had brought my car to maxxon mazda dealer for an oil change for a road trip and the service writer was so rude to me!

Anyway, i finally get my car back like two hours later. And I sit down and my radio staions were all messed up, basically i had the feelibg this jerk was messing around in my car.... i go to adjust the lumbar and the wheel was spinning and the lumbar was flat. So i go talk to this service jerk and he says oh not me i wasnt messing with your car, im like my stations are switched and the lumbar is broken. Hes like "oh no no it would take like a 200 pound person to pop that. It wasnt us." I look him up and down, he was no petite guy...I say what are you trying to say that i broke and im lying to you?! Hes like oh not me, we can't fix. I say let me talk to service manager, who was another jerk, so service writer guy is just arguing with me going back and forth trying to say im wrong. Finally i say i want the manager i dont want to hear it anymore...

Long story short, Maxxon mazda dealer totally blew me off, said it wasnt them, didnt offer any solutions to me, didnt try to appease me in any way and ever since then i have been driving around with the lumbar support broken... which now i want to try and fix since im fixing the headliner and everything.
