2011 Yukon power seat troubleshooting

My power drivers seat on my 2011 Yukon is malfunctioning and I'm hoping for some help to troubleshoot. The motor is not available as a replacement part and the dealer only sells the entire seat rail for +$600.

 

The motor will operate but is sluggish and stops after a few seconds of operation. The switch clicks regardless of the motor moving. The worm gear doesn't appear to be bound and moves when the motor operates. After recently moving the seat to the full forward position, the motor completely stopped working requiring manual movement of the seat to get it back to normal driving position. The power seat will work but slows and eventually stops even with the switch engaged.

 

I shot a quick video to capture the grinding noise:

 

This was taken from the floor looking under the seat with the worm gear on the left in the video frame.

 

Any advice is appreciated.

Bump. Does this sounds like a bad/failing electrical seat motor for those with electrical motor experience?

The seat motor on my 2011 GMC Sierra does the same thing. The back low to high function does the same thing as the video above. The front low to high function didn't move at all. I noticed the worm gear was moving. I opened up the little gear box and noticed the gear teeth were broken. I am pretty sure that is what is wrong with mine. I have found replacement one on eBay but seems expensive so I am currently looking for a cheaper alternative.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      4 low is really nice on steep boat ramps.

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
