Thanks for the excellent DIY writeup.

 

Rumor has it that the replacement lumbar mechanism from Cadillac has metal gears.

 

Does anyone have the part numbers for the motor? Mine just broke on my way home from work a day after I bought it, but was purchased without a warranty.

 

Hey there,

We do apologize for this, and we would be happy to reach out to an internal resource on your behalf for the part number. Please feel free to send us a private message along with your VIN. Looking forward to hearing from you soon.

I have a 2012 Suburban and the drivers seat up / down quit working for the seat. Front part of seat up / down works, rear part of seat up / down does not. I removed seat and motor and shaft were spinning to gear box. Disasembled gear box and one of the plastic gears is stripped. Anyone know if this is a serviceable item and if so where to get gear and how to install. Gear box comes apart enough just to see gears, not r & r.
Thanks

Driver side lumbar support just broke.

 

Hi
My name is Bob
I have a 2009 Tahoe LT
Vin # 1GNFK23079R255319
I was working on my failed seat heating elements (a whole other story) and adjusted the power lumbar and heard it pop. I already had the back of the seat off so I took the cover off the cable adjusting motor. As soon as I took the cover off it was obvious that the PLASTIC gear had shattered.
I called my local parts guy, Whom I have gotten to know very well because of the heated seat issue,and he said I would have to replace the whole frame for about $450....For a plastic gear?
I am hoping you can suggest another less expensive option.I have purchased a Chevy every 3 years for the last 30 years.
Thank You!
