Power seat question

I just purchased a pair of seats from a Chevy pickup, full power both seats. I hooked the hot wire and ground wire to power source and the driver seat is dead. Nothing from any of the functions,seat bottom, seat back or the lumbar, side bolsters. I don`t think everything went out at once. So my question is is the brain/computer for the seats bad or is there something i`m overlooking? The passenger seat seems to work in all functions when checking the same way except the back/forward function. It went forward but won`t go backwards, so i`m thinking maybe a good switch cleaning may take care of that problem. Any ideas here?

Well it looks like the memory function is the problem. It needs more than just a hot wire hooked up to make it work. I either have to find a seat track without the memory function or try to wire it up, which looks to be a huge pain.
