Lumbar seat adjustment broken

[Sir Dan]

Just wondering how many GMT900 people have a lumbar seat adjustment that doesn't work? My dads '10 escalade and my brother's '07 silverado both have passenger side in/out lumbar adjust that just makes a clicking noise when the button is pushed. Up/down works fine but not in/out. Seems like there must be a common issue there. How complicated is it to get to the problem part for a fix?

My dad had to replace his on the passenger side and it was a little over 150 and he did it himself

my 2007 escalade has the same issue. The replacement part is outragious as it is a whole unit and you cannot buy individual motor. On mine it appears the cables sliped off the whell in the motors transmission. I will be taking mine apart when I get gome after the holidays and will post up info

Thanks for the info guys. Interested to see if this really is a common problem and how easy it is to access and fix.

I read on another forum that the plasitc gears break and the replacement ones have metal gear. A module come with both mototrs and it you have a pop rivit gun to attach the motor to your original assembly you can use the up down motor to fix the other.

[hzhardy]

the whole assembly comes out. Yoy can see in the second pic it is only held on by a rivet

[Sir Dan]

Thanks for the pics. Maybe a trip to the u pull junkyard would turn up a cheap replacement.
