Anyone have any trouble with their power lumbar support? Mine just went out on my 07 Suburban. I took off the back cover and determined the motor is fine and the (plastic!!) gear on the motor is fine. The assembly that the motor goes into, that the tension cable comes out of, is stripped. I have checked all the local wrecking yards, and online but can't find place to get just the cable assembly. The dealer has the whole lumbar assembly (two motors and two cable assemblies, adjust the lumbar and lumbar height) in stock but they want $275. I wasn't able to get the part number from the guy but I'll try back again.

Just looking to see if anyone has had this issue and how they fixed it, or where they got replacement parts.
