Just wanted to follow up with this thread. I fixed my intermittent power seat in my 2007 tahoe ltz and it was simple. I just took off the plastic cover on the side of the driver's seat, then I unplugged all the connections that I saw, then reached under the seat and jiggled all the wires a bit, then plugged everything back in, and voila, I now have a 100% working power seat. Must have been a loose or corroded connection somewhere. It's been at least 3 months since I fixed it and it has worked 100% of the time. Hope this helps.
