Just noticed my 3rd row seat sometimes will not raise unless I lift it a bit to get it started. I'm wondering if there is anything that needs lubed? Battery seems fine.

The 3rd row seat on my '07 chattered noticably and would labor when raising. The vehicle was still under warranty so the dealer replaced the lift mechanism as the fix. There isn't any scheduled service but seems like I was able to look under the seat by removing "something" like a trim piece along the bottom. That would give you an idea if there's any lub on the mechanism or something has lodged causing the problem

NoJive, would you consider going to a dealer (as n7don did) for your seat concerns? As always, please feel free to email me for further assistance ([email protected]).

Katie,

I would take it to my local Cadillac dealer, however, bring that it is out of warranty, I will probably take it to the GM dealer that I purchased it from. They gave me a 30 day warranty, as well as a 10 year, 100,000 powertrain warranty. I was just hoping it was something I could do myself.

I can definitely understand that perspective, NoJive. Let me know if you do end up involving the dealer and would like any further assistance.

I had a chattering sound from mine.The 3rd row seat is moved by 2 cables from the L and R rails to the motor which is in the center of the 3rd row seat.
The lube dries out over time and the cable makes noise or gets stuck, so I took the cables out "very easy" cleaned them and used a syringe with bicycle cable lube and injected the lube into the cable case which in turn forced all the old dry lube out and then I lubed the cables put everything back together and the 3rd row seat works perfect. took about a 1/2 hour to fix. Good Luck

Excellent advice! I lubed what I could see, and saw the cables, just had no clue how to get them out to lube them. Any ideas?

Hi Jive, the cables are held in by a little screw I believe, one on each end. I did not have to take out the electric motor if I remember right. Once the cables are out they slide out easily. I did this about 2 years ago and do not remember exactly how they are held in but it is not difficult by any means. And the seat still works great. I think it is a lot easier if you unhook the seat cushion for access not 100% sure though I will check mine if you have problems. Good Luck

Thanks for the info, and the picture. I'll lube the cables on mine, and hopefully that will fix the issue. It's funny though, that once I get the seat raised, I can then raise and lower it without any problems. The other day, I lubed all the pivot points I could see, and it was working very smooth. But the next day, it wouldn't raise at all without help. I may end up pulling the seat out, and going over everything.

Those cables go from the electric motor to the little gear box on the outer rail on both sides and mine was also stuck and then when it would finally move, it sounded like a sick moose call from the dry lube in the cables . I believe the problem comes from minimal use of the 3rd row seat and the cables get dry and corroded and get seized and then we have our problems but once its lubed up its fine. I do not think it is a motor issue, it is the motor under strain from not being able to turn the dry cables which move the seat. you should not have to remove the seat as I did not to lube the cables and solve the problem. I forgot to mention just make sure the seat is raised if you can. I hope you can see how easy it is to fix because once you see it you will go, that's all there was to fix this. Good Luck

Ok, I'm gonna try and work on this today. I did give them a quick look the other day, and could not see how to disconnect the cables. I see where they go into the gearbox on the ends of the rails, but didn't see any screws there. I thought maybe if I could remove the bottom seat cushion, I'd have better access.

 

[NoJive]

I may have fixed it, time will tell. I could not figure out how to unscrew the cables at the rail end. I ended up removing the three bolts from the back seat, and tilting the seat up for access. From there I was able to unscrew the cables from the motor, and the cables themselves were gunked up pretty bad. I cleaned/lubed them, and the seat is a lot quieter now. I believe that the cables only control the seat sliding forward, and do not actually lift the seat. There is a 2nd motor that drives gears on either side that probably raises the seat. I lube those as best I could. Got my fingers crossed! Here is a pic of the cables going to the motor.

Hi Jive, glad to see you got to those cables. From your pictures that is what I remember the setup looks like, and like I said before I did mine 2 yrs ago and still works like new so you will not have to worry about it for sometime or maybe never. Great Job, Hope this solves your problem.
