Power seat issues, weird reclining problem.

Hi guys. I recently purchased a 2010 (my first Tundra). An hour after I purchased the vehicle I tried adjusting the seat forward, back, up and down and it all seemed to work. Then I tried to recline the seat and the button (missing cap) would not budge. It was just frozen. Then I kept messing with the forward and back and the more I messed with it, the more the seat would recline. No matter how I moved the seat the seat just kept reclining and reclining until it was all the way back. I drove the truck from Miami to Naples (2 hour trip) with no seat to my back. My first though was to replace the switch. I replaced the switch and I got the seat to recline but again no control. It just reclined all the forward and now it's stuck in that position. This is a weird one. Any thoughts? Thanks guys. Going nuts on this one.
